M51954B Overview

Description

M51953A,B/M51954A,B are semiconductor integrated circuits designed for detecting supply voltage and resetting all types of logic circuits such as CPUs. They include a built-in delay circuit to provide the desired retardation time simply by adding an external capacitor.

Key Features

  • Few external parts
  • Large delay time with a capacitor of small capacitance (td ≈ 100 ms, at 0.33 µF) (M51953, M51954)
  • Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage): 0.6 V (Typ) at RL = 22 kΩ
  • Wide supply voltage range: 2 V to 17 V
  • Wide application range
