HTH

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

level on this pin initially rises above V

/RST remains low or RST remains high for a minimum of 140ms.

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

is latched until V
