Pin Function
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
Ground.
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
Output: Active-high, open-drain output. This output is de-asserted and
latched when V
remains latched until V
Output: Push-pull output. This output is de-asserted and latched when V
< V
