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 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 ponents to detect user specified threshold voltages (NMOS open drain type only).
