Detailed Description for MIC2545A-2BM
Product Overview
The MIC2545A-2BM from Microchip Technology is a USB power switch and high-side load driver for controlled distribution to one output. It uses a non-inverting on/off interface, a 1:1 input-to-output ratio, and an N-channel high-side output for loads operating from 2.7 V to 5.5 V. The device is supplied in a surface-mount 8-SOIC package for compact power-path control in embedded systems.
Key Features
- Single high-side output with N-channel switching and a 1:1 input-to-output ratio.
- Rated for 2.7 V to 5.5 V load voltage and up to 3 A output current.
- Typical Rds On is 35 mOhm.
- Non-inverting on/off control with slew-rate-controlled output and status flag.
- Includes adjustable current limiting, over-temperature protection, and reverse-current protection.
- No separate Vcc/Vdd supply is required; surface-mount 8-SOIC package.
- Operating temperature range is -40°C to 85°C.
Applications
- USB port power control in hubs, docks, and peripheral devices.
- High-side switching of 2.7 V to 5.5 V loads in embedded power distribution.
- Controlled enable of current-limited power paths for downstream electronics.
Design & Procurement Notes
For layout, place the switch close to the USB connector or load to support the high-side power path. The adjustable current limit and status flag can provide fault indication and controlled enable behavior. The slew-rate-controlled output can be used to reduce switching transients when enabling downstream loads. The 8-SOIC surface-mount package and 2.7 V to 5.5 V load range make it suitable for single-output power-path designs.
