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 application range

Description

The REAR56957A IC is used for the resetting of all types of logic circuits, such as CPUs, and has the feature of setting the detection voltage by adding external resistance. The device includes a built-in delay circuit to provide the desired retardation time simply by adding an external capacitor. These ICs find extensive applications, including battery checking circuits, level detecting circuits, and waveform shaping circuits.
