V_IN

Supply voltage to the IC.

WDI

CMOS/TTL compatible input lead. The watchdog function

monitors the falling edge of the incoming signal.

Ground Connection

Delay

Input lead from timing capacitor for RESET and WAKE UP

signal.

RESET

CMOS/TTL compatible output lead RESET goes low when-

ever V_OUTdrops by more than 6% from nominal, or during

the absence of a correct watchdog signal.

WAKE UP CMOS/TTL compatible output consisting of a continuously

generated signal used to WAKE UP the microprocessor from

sleep mode.

V_OUT

Regulated output voltage 5V ± 2%.

Sense

Kelvin connection which allows remote sensing of the output

voltage for improved regulation. If remote sensing is not

required, connect to V_OUT
