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.

Features

  • Precise monitoring of 3V, 3.3V, and 5V supply voltages
  • Fully specified over temperature
  • 140ms min. Power-On Reset pulse width, 240ms typical Active-low RESET# Output (MCP809) Active-high RESET Output (MCP810)
  • Guaranteed RESET Output valid for VCC>=1V
  • Low Supply Current, 15µA typ.
  • Power supply transient immunity

Applications

  • Microprocessor Systems
  • Computers
  • Controllers
  • Intelligent Instruments
  • Portable/Battery-Powered Equipment
  • Automotive
