FP6808
Description
The FP6808 is a cost-effective system supervisor circuit designed to monitor microprocessor voltage and VDD in digital systems. This device provides a reset signal to the host processor when necessary.
The circuit asserts a reset signal whenever the VDD supply voltage declines below a preset threshold. It keeps reset signal asserted for at least 20ms after VDD has risen above the reset threshold.
The FP6808-N has an open-drain active-low output stage, while FP6808-C has a push-pull active-low output. The FP6808-N’s open-drain output requires a pull-up resistor.
The FP6808 is optimized to reject fast transient glitches on the VDD line. Low supply current makes this device suitable for portable equipment.
