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 output.
Seven standard reset voltage options are available, suitable for monitoring 5V, 3.
3V, and 3V supply voltages.
With a low supply current of only 15µA, the MCP809/810 are ideal for use in portable equipment.
The MCP809/MCP810 are available in the 3-pin SOT23 package.
