HT7022-1

1.Description
UMW HT70xx series is a three-port low voltage dete
ctor implemented with CMOS technology. This series
of detectors can detect fixed voltages of 2.2V~7V.
The detector consists of 4 parts: high-precision and
low-power standard voltage source, comparator, hys
teresis circuit, and output driver. CMOS technology
ensures low power consumption. Although the dete
ctor is mainly designed for fixed voltage detection, it
can also detect the threshold voltage specified by the
user through peripheral components (only for NMOS
open-drain type).

2.Features
Low power consumption, typical value: 2.0uA
Wide operating voltage range: 1.5V~12V
Low temperature drift detection voltage:
typical value ±50ppm/°C
Built-in hysteresis
High-precision voltage detection: ±3%
Small package: SOT89-3, TO92, SOT23-3

3.Applications
Battery detector, level selector
Power failure detector
Microcomputer reset
Non-volatile RAM signal storage protector
Battery storage backup
