Pin Name

Pin Function

1

HTH

High-Voltage Theshold (Input): Analog input to a comparator. When the

level on this pin initially rises above V

RST remains low for a minimum of 140ms.

2

GND

Ground

3

LTH

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

voltage monitor input assigned to detect a low voltage condition. When the

level on this pin falls below V

latched until V

4

RST

Reset (Output): Active-low, open-drain output. This output is asserted and

latched when V

remains latched until V

5

VDD

Power Supply (Input): Independent supply input for internal circuitry.
