Description
General part information
MCP809 Series
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 VCCsupply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 240ms after VCCrises above the threshold. The MCP809 has an active-lowRESEToutput, while the MCP810 has an active-high RESET output.
Seven standard reset voltage options are available, suitable for monitoring 5V, 3.3V, and 3V supply voltages.
