Data Sheet 10 Rev.1.3.1, 2011-06-27 TLE 6270 R Quad Low Side Injector Driver Functional Description 5 Functional Description 5.1 List of Functionalities The device performs the following functionalities: * * * * * * Load control - 4 low side power transistors driven by 4 parallel CMOS compatible inputs. Output current control - output current comparators and logic circuit to generate high side switches control signals NCTL2 and NCTL3. - current thresholds programmable by external resistor. Diagnostic of defective or missing injector connections and overtemperature - comparators and logic circuit to interpret unexpected current, voltages and HSDiag input status as short circuit or disconnection of the injector. - 4 thermal sensors for independent overtemperature detection on the 4 channels. Protection - all inputs/outputs: protection against ESD (all input and output pins) - T1, T4, internal power transistors: protection against overvoltage and Transients (Schaffner test pulses)... - external transistors connected via NCTL2 and CLT3: protection against overvoltage and Transients (Schaffner test pulses)... Reset - external reset (reset pin) - internal reset (undervoltage reset) Electro Magnetic Compatibility (EMC) These functionalities are described in the next chapters. 5.2 Load Control Each output transistor is switched on and off by an individual control signal (NON input). In normal operation, when NON is low, the transistor is ON and when NON is high the transistor is OFF. Also after power up, the outputs must have the status defined by the NON input. The logic level of the input is CMOS compatible. As there is an internal pull-up, the output transistor is switched off when the input is not connected. It is possible to drive two separate loads simultaneously as far as they do not belong to the same bank. Data Sheet 11 Rev.1.3.1, 2011-06-27 TLE 6270 R Quad Low Side Injector Driver Functional Description 5.3 Output Current Control From the output current comparators and inputs signals, a logic circuit controls the 4 current levels IPC, IP, IH and ID by commanding the high side drivers T2 and T3 via NCTL2 and NCTL3 (see Chapter 8). T2 and T3 are OFF when NCTL2 and NCTL3 are at high level. * * * * * IPC level is controlled between high and low values IPC value can be programmed through Pgr_IPC pin IP level the transition from IPC to IP is controlled by PCh pin IP value can be programmed through Pgr_IP pin IH level is controlled between high and low values the transition from IP to IH starts when peak level is reached IH value can be programmed through Pgr_IH pin ID level is controlled between high and low values. ID is equal to IH. the transition from IH to ID is controlled by NON1 or NON4 and PCh pins the damp pulse is not present if there is no damp pulse command at NON1/4 Currents values according to programming resistors (see also graph in Chapter 7) - R_Pgr_IP = kP / IP - R_Pgr_IPC = kPC / IPC - R_Pgr_IH = kH / IH The theoretical Design calculation leads to kP = 140000 = 8 x kPC = 4 x kH. Note: If Pgr_IPC pin has no resistor and is connected to VCC then there is no pre-charge and no damping. Then the Pch signal is not used and the output is controlled directly by the NON input.

It is also informed of too high current in the high side transistors via the HS_Diag pin. According to these comparator outputs and the NON signals, a logic circuit defines the failures (failure detection). When the failure is dangerous for the ECU, the engine management system, the vehicle or the car driver, all transistors T1, T2, T3, T4 are immediately switched off for protection (failure protection). Then, for limp home and for repairing, the failures are read by the microcontroller via SPI (failure information).

For the correct functionality of this feature a 5K resistor has to be connected in parallel with the freewheeling diode of each bank. OFF State Overvoltage Functionality: * * Comparator: - There is one comparator for two channels. A low level on the comparator output (called VOFF) means no failure. - The voltage on OUT1 (resp. OUT4) is checked at the OFF state between OUT1 and OUT4 ON states (resp. between OUT4 and OUT1 ON states). Filter time: For OUT1 (resp. OUT4), the filter time starts: - at H L transition on IN1 (resp. IN4) - if VOFF is high when this first filter time is finished - at every L H transition on VOFF HS Diag Filter Functionality: Min. 50ns , max.250ns Figure 12 HS Diag Filter Functionality (optionally only one out of NCTL2 or NCTL3 can be on at the same time) Diagnostic Control Circuit Functionality: The SC1 (resp.4) and OL1 (resp.4) failures are transferred in the SPI on IN1 and IN4 positive edges.

The SPI contains a failure register, a coder, a shift register, and a SDO driver: D7 CLK SDI SDO SDO DRIVER SHIFT REGISTER INJ1A_SC_stored INJ1A_SC INJ1A_OL_stored INJ1A_OL D6 INJ4A_SC_stored INJ4A_SC D5 INJ4A_OL_stored INJ4A_OL D4 D3 CODER INJ1B_SC_stored D2 FAILURE REGISTER INJ1B_OL_stored D1 INJ1B_SC INJ1B_OL D0 INJ4B_SC_stored INJ4B_SC FSL INJ4B_OL_stored INJ4B_OL NCS DIAGNOSTIC_CONTROL Figure 13 Failures Information Failure Register Each failure is stored in an individual register (this cannot be done directly in the shift register because a failure can occur while the shift register is being read). If the failure occurs, it remains until the SPI is read. The failure register is cleared when the SPI is read (FR_CLEAR signal). Output Coder The SC and OL failures of the 4 outputs are coded on an 8 bit word described hereafter: Data Sheet 17 Rev.1.3.1, 2011-06-27 TLE 6270 R Quad Low Side Injector Driver Functional Description D7 D6 D5 D4 D3 D2 D1 D0 FSL Failure indicator bit (only valid during NCS = LOW to the first L to H CLK change ) 1 = failure stored 0 = no failure Status INJ4B 11 = no failure 10 = short circuit 01 = shortcircuit Status INJ1B Status INJ4A Status INJ1A Figure 14 Output Coder Table 3 Failures Coding and Priorities valid for i=0 or i=2 or i=4 or i=6 Failure SPI Bits SC OL FSL Di+1 Di 0 0 0 1 1 0 1 1 0 1 1 0 1 1 0 1 1 1 1 0 The first bit of the shift register (FSL) is set to high level if there is a failure stored in the failure register. Input Coder t1 and t2 times are coded on 3 bit and 5 bit respectively as described hereafter: Data Sheet 18 Rev.1.3.1, 2011-06-27 TLE 6270 R Quad Low Side Injector Driver Functional Description D7 D6 D5 D4 MSB D3 D2 D1 LSB MSB D0 LSB t1 time 000: default value = 192 s LSB = 32s 111 = 416 s t2 time 00000 : default value = 0s LSB = 2s 111 = 62s Figure 15 Input Coder Table 4 describes the time coding: Table 4 Time Coding D7 D6 D5 D4 D3 D2 D1 D0 Time X X X X X 0 0 0 X X X X X 0 0 1 t1 = 192 s t1 = 224 s ... ...

The serial input is SDI. With the H/L change on NCS the first bit of the diagnostic shift register is transmitted to the SDO output. The CLK pin clocks the diagnostic shift register. New SDO data will appear on every CLK's rising edge and new SDI data will be latched into the shift register on every CLK's falling edge. With the first positive pulse of the CLK the failure register will be cleared by FR_CLEAR. There is no bus collision at a small spike at the NCS. The CLK is always LOW, while the NCS signal is changing. SPI Control The SPI control block monitors the data transfer from failure register to shift register and clear these register. This is done with the FR_SR_TRANS and FR_CLEAR signals as described in the following diagram: Data Sheet 19 Rev.1.3.1, 2011-06-27 TLE 6270 R Quad Low Side Injector Driver Functional Description NCS CLK SDO FSL SDI D0-OUT D1-OUT D2-OUT D3-OUT D4-OUT D5-OUT D6-OUT D7-OUT D0-IN D1-IN D2-IN D3-IN D4-IN D5-IN D6-IN D7-IN SPI Internal signals FR_SR_TRANS note: FR_SR_TRANS means failure transfer from the failure register into the shift register FR_CLEAR note: FR_CLEAR means clear of the failure stored of the failure register Figure 16 SPI Control SDO Driver The SDO driver drives the data on the diagnostic line. SDO is tri-stated when NCS is high.

Note: The protection latches are reset when the NON input is at high level. * * Protection against overvoltage A clamping circuit limits the output voltage to a defined value (Vclp) in order to avoid the breakdown of the output transistor when the solenoid load is switched off. Protection against turn on due to fast voltage ramp on output. A very fast voltage slope on the output can turn on the power transistor (capacitive effects) especially when the normal gate pull-down structure is not active (IC not supplied, VCC too low ...). In this case, the transistor is turned off immediately. This function is guaranteed for VCC between 0 and 5.5 V. 5.6 Reset There are two different reset functions: * * Undervoltage reset NRES reset pin If one or several of the following conditions are present: * * VCC lower than VCCRES, NRES pin at low level, the low side T1, T4 are switched off, NCTL2 and NCTL3 set to high level, all diagnostic registers are reset and the SDO is tri-stated.
