AF7040H Datasheet | AFSEMI

Features - Low power consumption - Low temperature coefficient - Built-in hysteresis characteristic AF70XXH series Low Power Voltage Detector - High input voltage (up to 15V) - Output voltage accuracy: tolerance ±2% - TO92, SOT89 SOT23-3 and SOT23 package Applications - Battery checkers - Level selectors - Power failure detectors - Microputer reset - Battery memory backup - Non-volatile RAM signal storage protectors General Description The AF70XXH 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 2.2V to 7.0V. The voltage detectors consist of a high-precision and low power consumption standard voltage source as well as a parator, hysteresis circuit, and an output driver. CMOS technology ensures low power consumption. Although designed primarily as fixed voltage detectors, these devices can be used with external...
