MICROCHIP MCP121T-450E/TT Voltage Detector, 1V-5.5V Supply, 4.38V Threshold, 120ms Delay, Active-Low, Open-Drain, SOT-23B-3

Product Overview

The MCP121T-450E/TT is a MicroPower Voltage Supervisor with active-low open-drain output. It is designed to keep a microcontroller in reset until the system voltage has reached and stabilized at the proper level for reliable system operation.

  • Resets microcontroller in a power-loss event
  • 1.75?A Ultra-low supply current (steady-state maximum)

Applications

Computers & Computer Peripherals, Sensing & Instrumentation, Portable Devices

Warnings

Market demand for this product has caused an extension in leadtimes. Delivery dates may fluctuate. Product exempt from discounts.
