HT7022A

HT7022A 2.2V Voltage Detector Features · Low detectable voltage 2.2V · Low power consumption · Low temperature coefficient · Built-in high-stability reference source · Built-in hysteresis characteristic · TO-92 and SOT-89 package Applications · Battery checkers · Power failure detectors · Microcomputer reset · Battery memory backup · Non-volatile RAM signal storage protectors General Description The HT7022A is a three-terminal low power voltage detector implemented in CMOS technology. It detects a particular fixed voltage 2.2V. The voltage detector consists of a high-precision and low power consumption standard voltage source, 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 (NMOS open drain type only).
