MCP120T-300I/TT

The MCP120T-300I/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 5kΩ 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.

• Holds microcontroller in reset until supply voltage reaches stable operating level
• Resets microcontroller during power loss
• Precision monitoring of 3, 3.3 and 5V systems
• Active low RESET pin
• Holds RESET for 350ms (typical)
• RESET to VCC = 1.0V
• Accuracy of +(-) 125mV for 5V systems and +(-)75mV for 3V systems over temp
• 45μA Typical operating current
