The MCP120 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). MCP120 is available in a TO-92, SOT23-3, and SN packages.
Additional Features
Holds microcontroller in reset until supply voltage reaches stable operating level
Resets microcontroller during power loss
Precision monitoring of 3V, 3.3V and 5V systems
7 voltage trip points available
Active low RESET pin
Open drain output
Internal pull-up resistor (5 kohm) for MCP130
Holds RESET for 35kΩ (typical)
RESET to VCC = 1.0V
Accuracy of +(-)125mV for 5V systems and +(-)75mV for 3V systems over temp
45uA typical operating current
Temperature range:
Industrial (I): -40C to +85C
