Microchip Technology MCP120
MCP120/130 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. Both devices are available with a choice of seven different trip voltages and both have open drain outputs.| Part No. | MCP120 |

DESCRIPTION
The Microchip Technology Inc. The MCP130 has an internal 5 kΩ pullup resistor. Both devices have active low RESET pins. The MCP120/130 will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point voltage. VDD VSS RST VDD MCP120 VSS RST MCP120 MCP130 SOT-23-3 150mil SOIC RST VDD...
