MIC2544A-1YMM Description

Short technical summary and product information.

The MIC2544A-1YMM from Micrel Inc. is an integrated high-side power switch optimized for low-loss DC power switching and power management applications, including ACPI. This cost-effective solution requires minimal external components for USB and ACPI compliance.

 

Key features include a precision resistor-programmable output current-limit up to 1.5A and a soft-start circuit to minimize inrush current. Thermal shutdown and current-limit functions protect both the switch and the connected device. The device offers reverse current flow blocking and a typical on-resistance of 120m℉.

 

Available in an 8-pin SOIC or MSOP package, the MIC2544A-1YMM operates from a 2.7V to 5.5V input. It provides an open-drain fault flag output to signal current-limiting or thermal shutdown events to a local controller. The enable signal is compatible with 3V and 5V logic.

 

Applications include USB power distribution, PCI bus power switching, notebook PCs, ACPI power distribution, PC card hot swap, and inrush current limiting.
