MIC2544A-1YMM Description

Short technical summary and product information.

The MIC2544A-1YMM 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 protection safeguard the switch and connected devices. An open-drain flag output signals current-limiting or thermal shutdown events to a local controller.

 

This device operates from a 2.7V to 5.5V input and has a maximum on-resistance of 120mΩ. It offers reverse current flow blocking and typical on-state supply current of 90µA. The switch has a slow turn-on time of 2ms and fast turn-off.

 

The MIC2544A-1YMM is available in an 8-MSOP package suitable for surface mounting. It is designed for applications such as USB power distribution, PCI bus power switching, notebook PCs, and PC card hot swap.
