Overview

AF70XXM series Low Power Voltage Detector Features  Low power consumption  Low temperature coefficient  Built-in hysteresis characteristic  High input voltage (up to 10V)  Output voltage accuracy: tolerance ±1% or ±2%  TO92, SOT89, SOT23-3 ,SOT23 and SOT23-5 package Applications  Battery checkers  Level selectors  Power failure detectors  Microcomputer reset  Battery memory backup  Non-volatile RAM signal storage protectors General Description The AF70XXM series devices are a set of three terminal low power voltage detectors implemented in CMOS technology.
Each voltage detector in the series detects a particular fixed voltage ranging from 0.
9V to 5.
0V.
The voltage detectors consist of a high-precision and low power consumption standard voltage source as well as a comparator, hysteresis circuit, and an output driver (CMOS inverter or NMOS open drain).
CMOS technology ensures low power consumption.
Although designed primarily as fixed voltage d...
