Additional Details:
The AME8809CEHA operates by comparing the input voltage to an internal reference voltage. When the input voltage falls below the threshold, the open-drain output is activated. The threshold voltage is typically fixed but can be selected from a range of options depending on the specific model. The open-drain output requires a pull-up resistor for proper operation. Refer to the Analog Microelectronics datasheet for detailed specifications, application examples, and recommended operating conditions.
