FP6809 - 3-Pin Microprocessor Reset Circuits

General Description

The FP6809 and FP6810 are cost-effective system supervisory circuits which are designed to monitor micro-processor voltage and VCC in digital systems.

They provide a reset signal to the host processor when necessary.

Key Features

  • Precision Monitoring of Power-Supply Voltage.
  • 140ms Guaranteed Minimum Reset Output Duration.
  • Low Supply Current.
  • VCC Transient Immunity.
  • Small SOT-23-3 Package.
  • No External Components.
  • Guaranteed Reset Valid to VCC=1V.
  • Available in Three Output Configurations Open-Drain Output (FP6809-N) Push-Pull Output (FP6809-C) Push-Pull RESET Output (FP6810-C).
  • RoHS Compliant.

FP6809/6810 3-Pin Microprocessor Reset Circuits Description The FP6809 and FP6810 are cost-effective system supervisory circuits which are designed to monitor micro-processor voltage and VCC in digital systems. They provide a reset signal to the host processor when necessary. These circuits assert a reset signal whenever the VCC supply voltage declines below a preset threshold. They keep reset signal asserted for at least 140ms after VCC has risen above the reset threshold. The FP6809-N has an open-drain output stage which requires a pull-up resistor while FP6809-C and FP6810-C have push-pull outputs. The FP6809 has an active-low output while the FP6810 has an active-high RESET output.
