Description

Regulated output voltage.

Input supply voltage.

CMOS compatible Watchdog input. The watchdog function monitors the falling edge of

the incoming signal.

Ground connection.

ENABLE control for the IC. Positive logic. If ENABLE control will not be used, connect

this pin to VIN via a 20k current limiting resistor. Internal ESD protection structures will

clamp the maximum ENABLE voltage to approximately 21 V.

CMOS compatible output RESET goes low whenever VOUT drops by more than 7.0%

from nominal, or during the absence of a correct watchdog signal.

Buffered reference voltage used to create timing current for RESET and Watchdog

threshold frequency from RDelay.

No Connection.

Continuously generated signal that interrupts the microprocessor from sleep mode.

Connect to Ground potential or leave unconnected.
