PIN SYMBOL
FUNCTION
VOUT
Regulated output voltage 5.0 V ± 2%.
VIN
Supply voltage to the IC.
WDI
CMOS/TTL compatible input lead. The Watchdog function
monitors the falling edge of the incoming signal.

Wake Up CMOS/TTL compatible output consisting of a continuously
generated signal used to Wake Up the microprocessor from sleep
mode.

15
RESET CMOS/TTL compatible output lead RESET goes low whenever
VOUT drops by more than 6.0% from nominal, or during the
absence of a correct watchdog signal.

Delay
Input lead from timing capacitor for RESET and Wake Up signal.

Sense
Kelvin connection which allows remote sensing of the output
voltage for improved regulation. If remote sensing is not required,
connect to VOUT.
*Pin 6 GND is not directly shorted to the fused paddle GND. The fused paddle GND (pins 4, 5, 12, 13) is connected through the substrate.
Pin 6 must be electrically connected to at least one of the fused paddle GND’s on the PC board.
