Microchip | MCP120T-315I/TT

The MCP120 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.

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.

Features:

• Holds microcontroller in reset until supply voltage reaches stable operating level
• Resets microcontroller during power loss
• Precision monitoring of 3 V, 3.3 V and 5 V systems
• 7 voltage trip points available
• Active low RESET pin
• Open drain output
• Internal pull-up resistor (5 kΩ) for MCP130
• Holds RRESET for 350 ms (typical)
• RESET to VCC = 1.0 V
• Accuracy of ±125 mV for 5 V systems and ±75 mV for 3 V systems over temperature
• 45 μA typical operating current
• Temperature range:
• Industrial (I): -40°C to +85°C
