Features & Applications

The MCP130 series of voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level.

MCP130 features an open drain output with internal 5K ohm internal pull-up resistor. MCP130 has active low reset and is available in a choice of seven different trip voltages. It operates over the extended industrial temperature range (-40°C/+85°C). MCP130 is available in a TO-92, SOT23-3, and SN packages. 


  • Holds microcontroller in reset until supply voltage reaches stable operating level
  • Resets microcontroller during power loss
  • Precision monitoring of 3 V, 3.3 V and 5 V systems
  • 7 voltage trip points available
  • Active low RESET pin
