AP22811AM8-13

Overview

The AP22811AM8-13 is a single-channel current-limited high-side power switch IC designed for USB and hot-plug applications. It operates within an input voltage range of 2.7V to 5.5V and features a typical on-resistance of 50mΩ. The device integrates soft-start with a typical rise time of 0.6ms and includes comprehensive protection against overcurrent, short circuit, and overtemperature conditions, all with auto-recovery capabilities. It offers reverse current blocking, undervoltage lockout, and a low-power shutdown mode consuming only 0.6μA. The component is housed in an MSOP-8 package.

Feature Summary

• Integrates fast response short-circuit protection and controlled output discharge for capacitive loads
• Provides reverse current blocking and automatic recovery from overcurrent, short circuit, and thermal faults
• Features a fault flag output with 6ms debounce capability to prevent false overcurrent reporting
• Supports both active-low and active-high enable inputs for flexible system control

Applications

• Laptop computer peripheral interfaces
• Tablet device power distribution
• Set-top box USB ports
• Consumer electronics hot-plug connections
• Telecommunications system power switching

Procurement Notes

Verify the specific suffix 'M8' corresponds to the MSOP-8 package variant required for your PCB footprint. Confirm that the 'A' designation aligns with the intended enable logic polarity for your design. Ensure compatibility with the 2.7V to 5.5V operating range. Check for RoHS compliance documentation if environmental regulations apply. Validate thermal performance requirements for the selected application scenario.

Selection Notes

Select this component when designing USB or hot-plug interfaces requiring integrated protection and precise power sequencing. It is suitable for applications needing low quiescent current in standby modes and robust fault handling without external components. Consider the MSOP-8 package constraints for space-limited designs. Evaluate the 50mΩ on-resistance impact on efficiency for your specific load currents. Ensure the enable pin configuration matches your system's control logic.
