MicroPowerâ¢ Microprocessor Reset Circuit

Function

Ground connection.

RESET output remains high while VCC is below the reset threshold

and remains so for a fixed time period after VCC raises above the

reset threshold.

RESET output remains low while VCC is below the reset threshold

and remains so for a fixed time period after VCC raises above the

reset threshold.

Supply voltage (+1.2V to +5.5V). Due to extremely low operating

current, place a 10nF capacitor between VCC and GND.
