H70xxA-1 Low Power Voltage Detector H70xxA-1 General Description The H70XXA-1 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 highprecision and low power consumption standard voltage source as well as a comparator, 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 components to detect user specified threshold voltages . Features ● Low power consumption ● Low temperature coefficient ● Built-in hysteresis characteristic ● High input voltage (up to 15V) ● Output voltage accuracy: tolerance ±1% or ±2% ● TO92, SOT89 ,SOT23 and SOT23-3 package Applications ● ● ● ● ● ● Battery checkers Level selectors Power failure detectors Microcomputer reset Battery memory backup Non-volatile RAM signal storage protectors 上海矽朋微电子有限公司 V2.0 第 1 页 共 19 页 H70xxA-1 Order Information Part No Detectable Voltage Hysteresis Width Tolerance H7022A-1 H7024A-1 H7027A-1 H7030A-1 H7033A-1 H7036A-1 H7039A-1 H7040A-1 H7044A-1 H7050A-1 H7070A-1 2.2V 2.4V 2.7V 3.0V 3.3V 3.6V 3.9V 4.0V 4.4V 5.0V 7.0V 0.11V 0.12V 0.135V 0.15V 0.165V 0.18V 0.195V 0.2V 0.22V 0.25V 0.35V ±2% ±2% ±2% ±2% ±2% ±2% ±2% ±2% ±2% ±2% ±2% Package TO92 SOT89 SOT23-3 SOT23 Manner of Packing Devices per bag/reel Bag 1000PCS/bag Reel 1000PCS/reel Reel 3000PCS/reel Reel 3000PCS/reel Note:H70①②A-1③④⑤ Designator Symbol ①② Integer ③ ④ ⑤ 上海矽朋微电子有限公司 Description Output Voltage(2.2~7.0V) N NMOS C CMOS T Package:TO-92 P Package:SOT89 M Package:SOT23-3 N Package:SOT23 R RoHS / Pb Free G Halogen Free V2.0 第 2 页 共 19 页 H70xxA-1 Block Diagram and Pin Arrangement Diagram Pin Assignment Pin No. Pin Name 1 VOUT 2 VIN Supply Voltage Input. 3 GND Ground connection. 上海矽朋微电子有限公司 Description Output.
