Microchip | MCP130-315I/SN

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. 

Features:

• Holds microcontroller in reset until supply voltage reaches stable operating level
• Resets microcontroller during power loss
