M51954B - Voltage Detecting / System Resetting

This page provides the datasheet information for the M51954B, a member of the M51953A Voltage Detecting / System Resetting family.

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.

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.
