NAME
FUNCTION
1
V
DD
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.
2
GND
Ground.
3
VSET1
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.

VSET3
6
RST/MR
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.
