REAR56957BG - Voltage Detecting / System Resetting IC

Download the REAR56957BG datasheet PDF. This datasheet also covers the REAR56957A variant, as both devices belong to the same voltage detecting / system resetting ic family and are provided as variant models within a single manufacturer datasheet.

Description

REAR56957A,B are semiconductor integrated circuits for resetting of all types of logic circuit such as CPUs, and have the feature of setting the detection voltage by adding external resistance.

Features

  • Few external parts.
  • Large delay time with a capacitor of small capacitance (td ≈ 100ms, at 0.33μF).
  • Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage): 0.6V (Typ. ) at RL = 22kΩ.
  • Wide supply voltage range: 2V to 17V.
  • Wide.
