FUNCTION
Supply Voltage and Monitored Input. The VDD 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, VTP.
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 VDD falls below VTH. 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 VDD 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 VDD that is pulled to GND (LOW)
when reset is asserted, VDD < 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.
