5 Power Stage
The power stages are built by an N-channel vertical power MOSFET (DMOS) with charge pump.
5.1 Output ON-State Resistance
The ON-state resistance RDS(ON) depends on the supply voltage as well as the junction temperature Tj. Figure 4
shows the dependencies for the typical ON-state resistance. The behavior in reverse polarity is described in
Chapter 6.4.
Figure 4 Typical ON-state resistance
A high signal (See Chapter 8) at the input pin causes the power DMOS to switch ON with a dedicated slope, which
is optimized in terms of EMC emission.

5.3 Inductive Output Clamp
When switching OFF inductive loads with high side switches, the voltage VOUT drops below ground potential,
because the inductance intends to continue driving the current. To prevent the destruction of the device due to
high voltages, there is a voltage clamp mechanism implemented that keeps the negative output voltage at a certain
level (VS-VDS(AZ)). Please refers to Figure 6 and Figure 7 for details. Nevertheless, the maximum allowed load
inductance is limited.

5.3.1 Maximum Load Inductance
During demagnetization of inductive loads, energy has to be dissipated in the BTS4130QGA. This energy can be
calculated with following equation:
Following equation simplifies under the assumption of RL = 0Ω.
The energy, which is converted into heat, is limited by the thermal design of the component. See Figure 8 for the
maximum allowed inductivity.

Protection Mechanisms
6 Protection Mechanisms
The device provides embedded protective functions. Integrated protection functions are designed to prevent the
destruction of the IC from fault conditions described in the data sheet. Fault conditions are considered as “outside”
normal operating range. Protection functions are designed for neither continuous nor repetitive operation.
6.1 Loss of Ground Protection
In case of loss of the module ground, where the load remains connected to ground, the device protects itself by
automatically turning OFF (when it was previously ON) or remains OFF, regardless of the voltage applied on IN
pins. In that case, a maximum I(OUTGND) can flow out of the output.
6.2 Undervoltage Protection
Below VSUV_max, the under voltage mechanism is met. If the supply voltage is below the under voltage mechanism,
the device is OFF (turns OFF). As soon as the supply voltage is above the under voltage mechanism, then the
device can be switched ON and the protection functions are operational.
6.3 Overvoltage Protection
There is a clamp mechanism for over voltage protection. To guarantee this mechanism operates properly in the
application, the current in the zener diode ZDAZ has to be limited by a ground resistor. Figure 9 shows a typical
application to withstand overvoltage issues. In case of supply greater than VS(AZ), the power transistor switches
ON and the voltage across logic section is clamped. As a result, the internal ground potential rises to VS - VS(AZ).
Due to the ESD zener diodes, the potential at pins IN and ST 0/1/2/3 rises almost to that potential, depending on
the impedance of the connected circuitry. Integrated resistors are provided at the IN pins to protect the input
circuitry from excessive current flow during this condition but an external resistor must be provided at the ST0/1/2/3
pins.

Protection Mechanisms
In the case the supply voltage is in between of VS(SC) max and VDS(AZ), the output transistor is still operational and
follow the input. If at least one channel is in ON state, parameters are no longer warranted and lifetime is reduced
compared to normal mode. This specially impacts the short circuit robustness, as well as the maximum energy
EAS the device can handle.
6.4 Reverse Polarity Protection
In case of reverse polarity, the intrinsic body diode causes power dissipation. The current in this intrinsic body
diode is limited by the load itself. Additionally, the current into the ground path and the logical pins has to be limited
to the maximum current described in Chapter 4.1, sometimes with an external resistor. Figure 10 shows a typical
application. The RGND resistor is used to limit the current in the zener protection of the device. Resistors RIN and
RST are used to limit the current in the logic of the device and in the ESD protection stage. The recommended value
for RGND is 150Ω, for RST 0/1 = 15kΩ. In case the over voltage is not considered in the application, RGND can be
replaced by a Shottky diode.

6.5.1 Current Limitation
At first step, the instantaneous power in the switch is maintained to a safe level by limiting the current to the
maximum current allowed in the switch IL(LIM). During this time, the DMOS temperature is increasing, which affects
the current flowing in the DMOS. At thermal shutdown, the device turns OFF and cools down. A restart mechanism
is used, after cooling down, the device restarts and limits the current to IL(SCR). Figure 11 shows the behavior of
the current limitation as a function of time.

Diagnostic Mechanism
7 Diagnostic Mechanism
For diagnosis purpose, the BTS4130QGA provides status pin.
7.1 ST 0/1/2/3 Pin
BTS4130QGA status pins are an open drain, active low circuit. Figure 12 shows the equivalent circuitry. As long
as no “hard” failure mode occurs (Short circuit to GND / Over temperature or open load in OFF), the signal is
permanently high, and due to a required external pull-up to the logic voltage will exhibit a logic high in the
application. A suggested value for the RPU ST01 is 15 kΩ.

Diagnostic Mechanism
7.2.1 Diagnostic in Open Load, Channel OFF
For open load diagnosis in OFF-state, an external output pull-up resistor (ROL) is recommended. For calculation
of the pull-up resistor value, the leakage currents and the open load threshold voltage VOL(OFF) has to be taken into
account. Figure 13 gives a sketch of the situation and Figure 14 shows the typical timing diagram.
Ileakage defines the leakage current in the complete system, including IL(OFF) (see Chapter 5.4) and external
leakages e.g. due to humidity, corrosion, etc... in the application.
To reduce the stand-by current of the system, an open load resistor switch SOL is recommended.
If the channel is OFF, the output is no longer pulled down by the load and VOUT voltage rises to nearly VS. This is
recognized by the device as open load. The voltage threshold is given by VOL(OFF). In that case, the ST 0/1 signal
is switched to a logical low VST01(L).

7.2.2 ST 0/1 Signal in case of Over Temperature
In case of over temperature, the junction temperature reaches the thermal shutdown temperature TjSC.
In that case, the ST 0/1 signal is toggling between VST01(L) and VST01(H). Figure 15 gives a sketch of the situation.

8.1 Input Circuitry
The input circuitry is CMOS compatible. The concept of the Input pin is to react to voltage transition and not to
voltage threshold. With the Schmidt trigger, it is impossible to have the device in an un-defined state, if the voltage
on the input pin is slowly increasing or decreasing. The output is either OFF or ON but cannot be in an linear or
undefined state. The input circuitry is compatible with PWM applications. Figure 16 shows the electrical equivalent
input circuitry. The pull down current source ensures the channel is OFF with a floating input.
