MCP130 Microcontroller Supervisory and Reset CircuitThe Microchip MCP130 is a Voltage Supervisor that holds a Microcontroller or other device in Reset during under-voltage conditions. During Start-Up and Brownout events the MCP130 asserts a Reset signal via an active-low Reset Pin. Integrated into the MCP130 is an internal 5 kΩ Pull-Up Resistor.FeaturesHolds Microcontroller in Reset until supply voltage reaches stable operating levelResets Microcontroller during power lossActive low RESET pinOpen drain outputInternal 5 kΩ Pull-Up ResistorHolds RESET for 350 ms (typical)RESET to VCC = 1.0VAccuracy of ±125 mV for 5V systems, ±75 mV for 3V systems over temperature45 μA typical operating currentSupervisory & Reset Circuits - Microchip
