4 / 7 page 3-Pin, Low-Power µP Reset Circuits 4 _______________________________________________________________________________________ VCC VCC GND MAX6802 RESET VCC GND RESET MOTOROLA 68HCXX μP 100k Ω Applications Information Interfacing to µPs with Bidirectional Reset Pins Since the RESET output on the MAX6802 is open-drain, this device interfaces easily with µPs that have bidirec- tional reset pins, such as the Motorola 68HC11. Connecting the µP supervisor’s RESET output directly to the microcontroller’s (µC’s) RESET pin with a single pullup resistor allows either device to assert reset (Figure 1). Negative-Going VCC Transients In addition to issuing a reset to the µP 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 Comparator Overdrive graph. The graph shows the maxi- mum pulse width that a negative-going VCC transient may typically have without issuing a reset signal. As the ampli- tude of the transient increases, the maximum allowable pulse width decreases. Figure 1.
