FUNCTION
Supply Voltage and Monitored Input. The V DD pin is the IC power supply terminal and also the
monitored input. The voltage at this pin is compared against the programmed voltage trip point, V TP .
A reset is first asserted when the device is initially powered up to ensure that the power supply has
stabilized. Thereafter, reset is again asserted whenever V DD falls below V TH . The device is designed
with hysteresis to help prevent chattering due to noise and is immune to brief power-supply transients.
Ground.
Voltage Trip Point Select Pins 1, 2 and 3. These inputs are either tied either to GND or V DD or left
floating in various combinations to program the falling voltage trip point. See Voltage Trip Point Setting
Table on following page for programming configurations.
Proprietary TwinPin? technology combines Active-Low Reset Output and Manual Reset Input
Functions into one pin. This dual function pin functions as both the reset output and a manual reset
input. The RST output pin has an integrated 100k pull-up resistor to V DD that is pulled to GND (LOW)
when reset is asserted, V DD < programmed voltage trip point. The MR input is an active-low
debounced input to which a user can connect a push-button to add manual reset capability.
