19-1294; Rev 4; 12/05 3-Pin, Ultra-Low-Power SC70/SOT P Reset Circuits The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/ MAX6348 microprocessor (P) supervisory circuits monitor the power supplies in P and digital systems. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.5V, 3V, 3.3V, and 5V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 100ms after VCC has risen above the reset threshold. The only difference between the devices is their output. The MAX6326/MAX6346 (push-pull) and MAX6328/ MAX6348 (open-drain) have an active-low reset output. The MAX6327/MAX6347 have an active-high push-pull reset output. All of these parts are guaranteed to be in the correct state for VCC down to 1V. The reset comparator is designed to ignore fast transients on VCC. Reset thresholds are factory-trimmable between 2.2V and 4.63V, in approximately 100mV increments. Twenty-one standard versions are available. Contact the factory for availability of nonstandard versions. Ultra-low supply currents (1A max for the MAX6326/ MAX6327/MAX6328) make these parts ideal for use in portable equipment. All six devices are available in space-saving SOT23 and SC70 packages.

Connecting the P supervisor's RESET output directly to the microcontroller's (C's) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 1). VCC VCC MAX6328 MAX6348 VCC P MOTOROLA RESET 68HCXX INPUT RESET Negative-Going VCC Transients In addition to issuing a reset to the P during power-up, power-down, and brownout conditions, these devices are relatively immune to short-duration, negative-going VCC transients (glitches). The Typical Operating Characteristics show the Maximum Transient Duration vs. Reset Threshold Overdrive graph, for which reset pulses are not generated. The graph shows the maximum pulse width that a negativegoing VCC transient may typically have when issuing a reset signal. As the amplitude of the transient increases, the maximum allowable pulse width decreases. GND GND Figure 1. Interfacing to Ps with Bidirectional Reset Pins Table 1.
