PIN(S) NAME DESCRIPTION
1 GND Negative reference for all signals.
2 RESET
Active low reset output. When the sence threshold has been exceeded, the RESET signal will remain
active for an additional 140ms(min.) after which it is taken inactive. During a "brownout" condition,
RESET
will immediately be taken active. Internal circuitry ensures RESET will remain active even when
the supply voltage is as low as 0V.
3V
CC
Supply input signal which is monitored by the sense comparator. This input is compared to the 2.93V or
4.63 reference to determine the state of the output.
