G657 - Microprocessor Reset IC

Download the G657 datasheet PDF. This datasheet also covers the G656 variant, as both devices belong to the same microprocessor reset ic family and are provided as variant models within a single manufacturer datasheet.

Description

The G656/G657 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems.

They provide excellent circuit reliability and low cost.

Features

  • Precision Monitoring Voltage of +2.2V and +3.7V.
  • Fully Specified Over Temperature.
  • Available in Three Output Configurations Push-Pull RESET Output (G656L) Push-Pull RESET Output (G656H) Open-Drain RESET Output (G657L).
  • Reset Deassert Time Smaller than 100µs when VCC Higher than Monitor Voltages (CD Pin Floating).
  • Externally Programmable Time Delay Generator.
  • 27µA Supply Current at VCC=3.3V.
  • Guaranteed Reset Valid to VCC = 0.8V.
