MIC24045 regulator features

The MIC24045 is a digitally programmable, 5A valley current-mode controlled regulator featuring an input voltage range from 4.5V to 19V.

The MIC24045 is perfectly suited for multiple voltage rail application environments, typically found in computing and telecommunication systems.

Thermal Warning and Thermal Shutdown

The MIC24045 has a thermal shutdown protection that prevents operation at excessive temperature. The thermal shutdown threshold is typically set at +160°C with a hysteresis of +25°C.

The MIC24045 features a Thermal Warning flag that is readable through the I2C interface (register polling is needed). The Thermal Warning flag signals the approaching of thermal shutdown, so that appropriate system-level countermeasures can be undertaken.
