RT9818 - Micro-Power Voltage Detectors

Description

The RT9818 is a micro-power voltage detector designed to supervise the power supply voltage levels for microprocessors (P) or digital systems.

It provides internally fixed threshold levels with 0.1V increments, ranging from 1.2V to 5V, covering most digital applications.

Features

  • a low supply current of 3A. The RT9818 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal persists until VDD recovers and surpasses the threshold level, at which point the reset signal is released after a certain delay time. The RT9818 is available in SC-82, SC-70-3, SOT-23-3, SOT-23-5, and SOT-89 packages. The recommended junction temperature range is.
  • 40C to 125C, and the ambient temperature ra.
