Fiti FP6809
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.| Part No. | FP6809 |

DESCRIPTION
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. The FP6809 and FP6810 are optimized to reject fast transient glitches on the VCC line. Low supply current makes these devices suitable for portable equipments.FEATURES
