MIC2549A - Programmable Current Limit High-Side Switch

Download the MIC2549A datasheet PDF. This datasheet also covers the MIC2545A variant, as both devices belong to the same programmable current limit high-side switch family and are provided as variant models within a single manufacturer datasheet.

Description

The MIC2545A and MIC2549A are integrated high-side power switches optimized for low-loss DC power switching and other power-management applications, including advanced configuration and power interface (ACPI).

Features

  • include a precision, resistor-programmable output current-limit and a soft-start circuit, which minimizes inrush current when the switch is enabled. Thermal shutdown, along with adjustable currentlimit, protects the switch and the attached device. The MIC2545A/49A’s open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller. The MIC2549A has an additional internal latch which turns the output off upon thermal shutdown, providing robust fault control. Th.

MIC2545A/2549A Programmable Current-Limit High-Side Switch General Description The MIC2545A and MIC2549A are integrated high-side power switches optimized for low-loss DC power switching and other power-management applications, including advanced configuration and power interface (ACPI). The MIC2545A/49A is a cost-effective, highly-integrated solution that requires few external components to satisfy USB and ACPI requirements. Load current management features include a precision, resistor-programmable output current-limit and a soft-start circuit, which minimizes inrush current when the switch is enabled. Thermal shutdown, along with adjustable currentlimit, protects the switch and the attached device.
