The MIC2549A-1YM-TR is an integrated high-side power switch from Microchip Technology, designed for low-loss DC power switching and power management applications. It offers a cost-effective solution with features like resistor-programmable output current-limit up to 3A and a soft-start circuit to minimize inrush current.
Key electrical specifications include a maximum on-resistance of 50mOhm and typical supply currents of 90uA (on-state) and 1uA (off-state). The device operates over an input voltage range of 2.7V to 5.5V. It includes fault protection features such as current limiting, over-temperature shutdown, and reverse current blocking.
This switch is suitable for applications like USB power distribution, notebook PCs, and ACPI power management. It comes in an 8-SOIC package and is designed for surface mount installation. The enable signal is compatible with 3V and 5V logic, and the MIC2549A variant includes an internal latch for thermal shutdown fault control.
The MIC2549A-1YM-TR provides an open-drain fault flag output to indicate current-limiting or thermal shutdown conditions to a local controller. Its design prioritizes integration and requires few external components for USB and ACPI compliance.
