MCP130 Microcontroller Supervisory and Reset Circuit
The 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.
