X4003 - CPU Supervisor

General Description

These devices combine three popular functions, Power-on Reset Control, Watchdog Timer, and Supply Voltage Supervision.

This combination lowers system cost, reduces board space requirements, and increases reliability.

Key Features

  • Selectable watchdog timer.
  • Select 200ms, 600ms, 1.4s, off.
  • Low VCC detection and reset assertion.
  • Five standard reset threshold voltages nominal 4.62V, 4.38V, 2.92V, 2.68V, 1.75V.
  • Adjust low VCC reset threshold voltage using special programming sequence.
  • Reset signal valid to VCC = 1V.
  • Low power CMOS.
  • 12µA typical standby current, watchdog on.
  • 800nA typical standby current watchdog off.
  • 3mA active current.
