MIC2545A-2YM Description

Short technical summary and product information.

The MIC2545A-2YM from Microchip Technology is an integrated high-side power switch optimized for DC power switching and power management applications. It offers a cost-effective solution with features like a precision, resistor-programmable output current-limit and a soft-start circuit to minimize inrush current.

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V, an adjustable current limit up to 3A, and a maximum on-resistance of 50mΩ. The device also provides reverse current flow blocking, thermal shutdown, and an open-drain fault flag for indicating current-limiting or thermal shutdown conditions.

 

Designed for applications such as USB power distribution, notebook PCs, and ACPI power distribution, the MIC2545A-2YM requires few external components. It is available in an 8-SOIC package, suitable for surface mounting.

 

This switch is compatible with both 3V and 5V logic for its enable signal. The typical on-state supply current is 90µA, and the off-state supply current is 1µA.
