AP2151AW-7

Overview

The AP2151AW-7 is a single-channel high-side power switch IC from Diodes Incorporated, designed for USB power distribution. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers a continuous output current of 500 mA with an 800 mA current limit. The device features a maximum on-resistance of 115 mOhms, ensuring efficient power transfer. Key timing parameters include a maximum turn-on time of 50 µs and a maximum turn-off time of 10 µs. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a compact SOT-25-5 surface-mount package.

Feature Summary

• Single-channel high-side switching capability for precise load control
• Integrated current limiting protects downstream circuits from overcurrent conditions
• Low on-resistance minimizes power loss and heat generation during operation

Applications

• USB port power management and distribution
• Battery-powered portable electronic devices
• Peripheral circuit protection in consumer electronics

Procurement Notes

Verify the specific suffix AW-7 against official Diodes Incorporated documentation to confirm pinout compatibility and package type. Ensure the procurement source provides valid RoHS compliance certificates as specified in the product attributes. Cross-reference the manufacturer part number with authorized distributor databases to avoid counterfeit components. Confirm that the delivered units match the SOT-25-5 package designation required for your PCB layout.

Selection Notes

Select this component when a single-channel high-side switch with 500 mA continuous current capacity is required. It is suitable for applications needing low on-resistance and fast switching speeds within a 2.7 V to 5.5 V supply range. Consider the SOT-25-5 package size for space-constrained designs. Verify that the thermal performance meets the system requirements given the 115 mOhm maximum resistance.
