MCP120T-315I/TT Datasheet PDF - Microchip

The MCP120T-315I/TT is a 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. MCP120 features an open drain output and 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). The MCP130 has an internal 5kR pull-up resistor. Both devices have active low RESET pins. The MCP120 will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point voltage.
