GENERAL DESCRIPTION
The ADCMP671 voltage monitor consists of two low power, high
accuracy comparators and reference circuits. It operates on a
supply voltage from 1.7 V to 5.5 V and draws 17 μA maximum,
making it suitable for low power system monitoring and portable
applications. The part is designed to monitor and report supply
undervoltage and overvoltage fault. The low input bias current
and voltage reference allows resistor adjustable UV and OV
threshold down to 400 mV. 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 overvoltage. This output combination allows
users to window monitor N supplies with an N + 1 processor
input/output (I/O). Each output is guaranteed to sink greater
than 5 mA over temperature.
The ADCMP671 is available in 6-lead TSOT package. The
device operates over the 40°C to +125°C temperature range.
