5V μP Power Supply Monitor and Reset Circuit
January 2005
rev 1.5
Notes
1. PBRST is internally pulled HIGH to V
CC
through a nominal 40k
resistor.
2. RESET is an open drain output.
3. RESET remains within 0.5V of V
CC
on power-down until V
CC
falls below 2V. RESET remains within 0.5V of ground on power-down until V
CC
falls below 2.0V.
4. Must not exceed the minimum watchdog time-out period (t
TD
). The watchdogcircuit cannot be disabled. To avoid a reset, ST must be strobed.
