MCP120-450I/SN Description

Short technical summary and product information.

The Microchip Technology MCP120-450I/SN is a voltage supervisory IC designed to ensure system stability by holding a microcontroller in reset until the supply voltage reaches a proper operating level and stabilizes. It also provides protection against brown-out conditions when the supply voltage drops below a safe threshold.

 

This device operates within a voltage range of 1.0V to 5.5V and has a specific trip voltage of 4.375V. The reset signal is active low, and the output configuration is open drain or open collector. It monitors a single voltage channel and provides a reset timeout of a minimum of 150ms. The typical operating current is 45µA.

 

The MCP120-450I/SN is housed in an 8-SOIC package with a surface mount type. It is rated for an industrial operating temperature range of -40°C to +85°C. The accuracy for 5V systems is ±125mV, and for 3V systems, it is ±75mV over temperature.
