PAK SO−16L
7 1 8 V
OUT
Regulated output voltage 5.0 V ± 2%.
8 2 9 V
IN
Supply voltage to the IC.
9 3 11 WDI CMOS/TTL compatible input lead. The Watchdog function monitors the falling
edge of the incoming signal.
3−5,
10−12
4 4, 5, 6, 12, 13* GND Ground connection.
13 5 14 Wake Up CMOS/TTL compatible output consisting of a continuously generated signal used
to Wake Up the microprocessor from sleep mode.
14 6 15 RESET CMOS/TTL compatible output lead RESET goes low whenever V
OUT
drops by
more than 6.0% from nominal, or during the absence of a correct watchdog
signal.
1 7 16 Delay Input lead from timing capacitor for RESET and Wake Up signal.
6 − 7 Sense Kelvin connection which allows remote sensing of the output voltage for im-
proved regulation. If remote sensing is not required, connect to V
OUT
.
*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.
