DESCRIPTION
The ADCMP671 voltage monitor consists of two low power, highaccuracy comparators and reference circuits.
It operates on asupply voltage from 1.7 V to 5.5 V and draws 17 μA maximum,making it suitable for low
power system monitoring and portableapplications. The part is designed to monitor and report supply under
voltage and overvoltage fault. The low input bias currentand voltage reference allows resistor adjustable UV
and OVthreshold down to 400 mV. The ADCMP671 has two opendrain outputs: the PWRGD output indicates
that the supply iswithin the UV and OV window, and the OV output indicatesthat the supply is overvoltage.
This output combination allowsusers to window monitor N supplies with an N + 1 processorinput/output (I/O).
Each output is guaranteed to sink greaterthan 5 mA over temperature.The ADCMP671 is available in 6-lead
TSOT package. Thedevice operates over the −40°C to +125°C temperature range.
