G681 - Microprocessor Reset

Download the G681 datasheet PDF. This datasheet also covers the G680 variant, as both devices belong to the same microprocessor reset family and are provided as variant models within a single manufacturer datasheet.

General Description

The G680/G681 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems.

High- and Low- voltage thresholds can be adjusted independently, allowing for wide hysteresis.

Voltage detection thresholds are accurate to 2%.

Key Features

  • High ±2% Voltage Threshold Accuracy.
  • Independently Adjustable High- and Low- Voltage Thresholds.
  • Fully Specified Over Temperature.
  • Available in Three Output Configurations Push-Pull RESET Output (G680L) Push-Pull RESET Output (G680H) Open-Drain RESET Output (G681L).
  • 140ms min Power-On Reset Pulse Width.
  • 4µA Supply Current.
  • Power Supply Transient Immunity.
  • 5-Pin SOT23-5 Packages.
