1

HTH

High-Voltage Threshold (Input): Analog input to a comparator. This is the

voltage input assigned to detect a high-voltage condition. When the level on

this pin exceeds V

V

2

GND

Ground.

3

LTH

Low-Voltage Threshold (Input): Analog input to a comparator. This is the

voltage input assigned to detect a low voltage condition. When the level on

this pin falls below V

until V

4

OUT (“N” Version)

Output: Active-high, open-drain output. This output is de-asserted and

latched when V

remains latched until V

OUT (“H” Version)

Output: Push-pull output. This output is de-asserted and latched when V
