ADM6384 - Microprocessor Supervisory Circuit

Description

The ADM6384 is a supervisory circuit that monitors power supply voltage levels in microprocessor-based systems.

A power-on reset signal is generated when the supply voltage rises to a preset threshold level.

Features

  • Precision power supply monitoring 31 reset threshold options 1.58 V to 5.0 V Four reset timeouts 1 ms, 20 ms, 140 ms, 1120 ms Manual reset input Reset output stage Push-pull active-low Guaranteed reset output valid to VCC = 1 V Power supply glitch immunity Specified over.
  • 40°C to +125°C temperature range 4-lead SC70 package.
