描述 Description

The FP6811 and FP6812 are cost-effective system supervisory circuits which are designed to monitor the power supply status
in micro-processor (μP) and digital systems.  In addition, they provide a de-bounced manual reset input pin to initiatea reset. 
These circuits assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for
at least 140ms after VCC has risen above the reset threshold.  The FP6811-N has an open-drain output stage, while FP6811-C and FP6812-C have push-pull outputs.  The FP6811-N’s open-drain output requires a pull-up resistor.  The FP6811 has an
active-low  output while the FP6812 has an active-high RESET output.  The FP6811 and FP6812 are optimized to reject fast transient glitches on the VCC line.  A low supply current makes these devices suitable for portable equipment.  Each device is available in SOT-23-5, SC-82 and SOT-143 packages.
