HT7033A-1 - (HT70xxA-1) Voltage Detector

Download the HT7033A-1 datasheet PDF. This datasheet also covers the HT7044A-1 variant, as both devices belong to the same (ht70xxa-1) voltage detector family and are provided as variant models within a single manufacturer datasheet.

General Description

The HT70xxA-1 series devices area 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 8.2V.

Key Features

  • Low power consumption.
  • Low temperature coefficient.
  • High input voltage range (up to 30V).
  • Quiescent current 3μA.
  • Output voltage accuracy: tolerance ±3%.
  • Built-in hysteresis characteristic.
  • 3-pin TO92, 3-pin SOT89, 3-pin SOT23 and 5-pin SOT23 package.
