MCP809-3 pin microprocessor reset circuit
The MCP809/810 microprocessor supervisory circuit is used to monitor the power supply digital system of the microprocessor. They provide a microprocessor reset during power-up, power-down and brown-out conditions. The function of the MCP809/810 is to monitor the VCC supply voltage whenever this assertion reset signal voltage falls below the factory programmed reset threshold. The reset signal is still asserted as 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 voltages are available, suitable for monitoring 5V, 3.3V and 3V supply voltages. With low supply current of only 15µA, the MCP809/810 are ideal for use in portable equipment. The MCP809/MCP810 are available in a 3-pin SOT23 package.
