Overview
The AP22716AKEWT-7 is a USB power switch IC manufactured by Diodes Incorporated, designed for high-side load switching applications. It operates within a supply voltage range of 2.7V to 5.5V and supports an output current of up to 2A. The device features a low on-resistance of 75 milliohms and includes comprehensive protection mechanisms such as fixed current limiting, over-temperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). It provides status flag indication and load release functionality in a compact TSOT-25 surface-mount package, suitable for temperatures ranging from -40°C to +85°C.
Feature Summary
- Integrated high-side N/P channel power switch with non-inverting control logic
- Built-in protection against over-current, thermal overload, reverse current flow, and short circuits
- Provides visual or electrical status indication via a dedicated status flag pin
- Supports load release capabilities for controlled power-down sequences
Applications
- USB port power management and distribution
- High-side switching for peripheral devices
- Load protection in consumer electronics
- Battery-powered equipment requiring efficient power routing
Procurement Notes
Verify the specific suffix 'AKEWT-7' to ensure correct packaging and tape-and-reel quantity specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the required temperature grade and package variant to avoid functional mismatches in final assembly.
Selection Notes
Select this component when a single-channel high-side switch with integrated fault protection is required for USB or similar low-voltage interfaces. The 2A current rating and 75mΩ on-resistance make it suitable for driving moderate loads efficiently. Consider the TSOT-25 package size for space-constrained designs requiring surface-mount technology.
Part Context
This part belongs to the AP22xxx series of USB power switches from Diodes Incorporated. These components are engineered to replace discrete MOSFET solutions, offering reduced board space and enhanced reliability through integrated protection circuitry. The series is widely used in portable devices and computer peripherals requiring robust power distribution management.
Replacement Considerations
Check for direct substitutes within the AP228xx series if pin compatibility and electrical parameters align. Verify that alternative parts maintain the same TSOT-25 footprint and support the required 2A current capacity. Ensure replacement options offer equivalent protection features such as UVLO and over-temperature shutdown.
