ME7044A Datasheet | Unknown Manufacturer

Description The ME70XXA series is 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 2.4V to 5V. The voltage detectors consist of a high-precision voltage divider circuit, band gap voltage source, a parator and an output driver. CMOS technology ensures low power consumption. Although designed primarily as fixed voltage detectors, these devices can be used with external ponents to detect user specified threshold voltages (NMOS open drain type only). Features - Low power consumption - Low temperature coefficient - Built-in high-stability reference source - Built-in hysteresis characteristic - TO-92 and SOT-23 package Applications - Battery checkers - Level selectors - Power failure detectors - Microputer reset - Battery memory backup - Non-volatile RAM signal storage protector Selection Table Part No. ME7027A ME7044A Detectable Voltage 2.7V 4.4V Hysteresis Width 0.13V 0.22V ..
