HT7033 - three-port low voltage detector

Download the HT7033 datasheet PDF. This datasheet also covers the HT7020 variant, as both devices belong to the same three-port low voltage detector family and are provided as variant models within a single manufacturer datasheet.

General Description

UMW HT70xx series is a three-port low voltage detector 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, hysteresis circuit, and output driver.

Key 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 Non-volatile RAM signal storage protector Battery storage backup 4.Pinning information Pin number TO-92/SOT89-3 SOT23-3 1 1 2 3 3 2 Symbol OUT VDD GND.

UMW HT70xx Ver 2.0 1.Description UMW HT70xx series is a three-port low voltage detector 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, hysteresis circuit, and output driver. CMOS technology ensures low power consumption. Although the detector 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). 3.Applications Battery detector, level selector Power failure detector Microcomputer reset 2.Features Low power consumption, typical value: 2.0uA Wide operating voltage range: 1.
