SOIC−8 EP
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 V
clamp the maximum ENABLE voltage to approximately 21 V.
CMOS compatible output RESET goes low whenever V
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 R
No Connection.
Continuously generated signal that interrupts the microprocessor from sleep mode.
Connect to Ground potential or leave unconnected.
