Pin Function
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.
Ground
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
Reset (Output): Push-pull output. This output is asserted and latched when
