Pin Descriptions
PIN SYMBOL
DESCRIPTION
1 GND Ground pin. Sets the Comparator output low level.
2
V- Negative Supply Input for Voltage Reference and
Comparator.
3 IN+ Comparator non-inverting input pin. Range: V- to
V+ -1.5V.
4 IN- Comparator inverting input pin. Range: V- to V+ -1.5V
5 HYST Comparator Hysteresis input. Accepts a voltage divided
from the Reference output. Range is VREF - 50mV to
VREF. Connect directly to VREF for zero hysteresis.
6 REF Reference output. Source 2mA and Sink 10µA.
7 V+ Positive Supply Input for Comparator and Reference.
Range is 2.0V to 11.0V
8 OUT Comparator output, CMOS push-pull. Output swing
referenced to V+ and GND.
