ADCMP671 - Adjustable UV and OV Monitor

General Description

The ADCMP671 voltage monitor consists of two low power, high accuracy comparators and reference circuits.

Key Features

  • Window monitoring with minimum processor I/O Individually monitoring N rails with only N + 1 processor I/O 400 mV, ± 0.275% threshold at VDD = 3.3 V, 25°C Supply range: 1.7 V to 5.5 V Low quiescent current: 17 μA maximum at 125°C Input range includes ground Internal hysteresis: 9.2 mV typical Low input bias current: 2.5 nA maximum Open-drain outputs Power good indication output Designated over voltage indication output Low profile (1 mm), 6-lead TSOT package.
