Microchip Voltage Supervisor 3-Pin TO-92, MCP130-475DI/TO

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.

Holds Microcontroller in Reset until supply voltage reaches stable operating level
Resets Microcontroller during power loss
Active low RESET pin
Open drain output
Internal 5 kΩ Pull-Up Resistor
Holds RESET for 350 ms (typical)
RESET to VCC = 1.0V
Accuracy of ±125 mV for 5V systems, ±75 mV for 3V systems over temperature
45 μA typical operating current
