FP6809/6810

3-Pin Microprocessor

Reset Circuits

Description

Features

The FP6809 and FP6810 are cost-effective system

supervisory circuits which are designed to monitor

micro-processor voltage and V_CCin digital systems.

They provide a reset signal to the host processor

when necessary.

 Precision Monitoring of Power-Supply Voltage

 140ms Guaranteed Minimum Reset Output

Duration

 Low Supply Current

 V_CCTransient Immunity

 Small SOT-23-3 Package

 No External Components

 Guaranteed Reset Valid to V_CC=1V

 Available in Three Output Configurations

These circuits assert a reset signal whenever the

V_CCsupply voltage declines below a preset

threshold. They keep reset signal asserted for at

least 140ms after V_CChas risen above the reset

threshold.

Open-Drain ꢀꢁꢀꢂ Output (FP6809-N)

Push-Pull ꢀꢁꢀꢂ Output (FP6809-C)

Push-Pull RESET Output (FP6810-C)

 RoHS Compliant

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 ꢀꢁꢀꢂ output while the

FP6810 has an active-high RESET output.

Applications

 Computer

The FP6809 and FP6810 are optimized to reject

fast transient glitches on the V_CCline. Low supply

current makes these devices suitable for portable

equipments.

 Battery Powered Equipment

 Microprocessor Power Supply Monitoring

 Embedded System

 Automotive
