Overview
MCP809/MCP810 3-Pin Microprocessor Reset Circuits June 2001 MCP809/MCP810 3-Pin Microprocessor Reset Circuits General Description The MCP809/810 microprocessor supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems.
They provide a reset to the microprocessor during power-up, power-down and brown-out conditions.
The function of the MCP809/810 is to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold.
The reset signal remains asserted for 240ms after VCC rises above the threshold.
The MCP809 has an active-low RESET output, while the MCP810 has an active-high RESET o...
