SGM891B Datasheet Voltage Detector

Manufacturer: SG Micro

Overview: SGM890B/SGM891B Voltage Detector with Separated Sense Pin and Delay Capacitor Pin.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The SGM890B and SGM891B are low-power and high-accuracy voltage detectors.

The adjustable threshold range is 0.8V to 5.0V with increments of 0.1V, which greatly provides application flexibility.

Since the sense pin (VSEN) of the device is separated from the power supply pin, it can monitor other power supplies.

Key Features

  • Operating Voltage Range: 1V to 6V.
  • High Accuracy Detection: ±1% (TYP).
  • Low Power Consumption: 0.3μA (TYP) at VIN = 1V.
  • Detection Voltage Range: 0.8V to 5.0V (0.1V Increments).
  • Detection Voltage Temperature Coefficient: ±40ppm/℃ (TYP).
  • Adjustable Release Delay Time (SGM890B Only).
  • Sense Pin Separates from Power Supply.
  • N-Channel Open-Drain Output.
  • -40℃ to +125℃ Operating Temperature Range.
  • Available in a Green SOT-23-5 Package.
