The ADCMP671-1YUJZ-RL7 is a low power high accuracy adjustable UV and OV monitor Comparator and Reference Circuit. It operates on a supply voltage from 1.7 to 5.5V and draws 17μA maximum, making it suitable for low power system monitoring applications. The part is designed to monitor and report supply under-voltage and over-voltage fault. The low input bias current and voltage reference allows resistor adjustable UV and OV threshold down to 400mV. The ADCMP671 has two open-drain outputs, the PWRGD output indicates that the supply is within the UV and OV window and the OV output indicates that the supply is over-voltage. This output combination allows users to window monitor N supplies with an N + 1 processor input/output. Each output is guaranteed to sink greater than 5mA over-temperature.
