Overview
The AP21510FM-7 is a single-channel high-side power switch IC designed for USB 2.0 current-limited applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features an output current capability of 200 mA with a maximum current limit of 400 mA. The device incorporates a low on-resistance of 110 mOhms, ensuring efficient power delivery. Key timing parameters include a maximum turn-on time of 50 us and a maximum idle time of 140 us. It is housed in a U-DFN2018-6 surface-mount package and supports operation across a temperature range of -40 C to +85 C.
Feature Summary
- Provides integrated overcurrent protection with defined current limiting thresholds for load safety.
- Features fast switching characteristics with controlled turn-on and idle times to manage inrush currents.
- Designed for compact layouts using a small footprint U-DFN2018-6 surface-mount package.
Applications
- USB 2.0 port power distribution
- Peripheral device power switching
- Battery-powered equipment load management
Procurement Notes
Verify the specific suffix FM-7 against the manufacturer's official datasheet to confirm pinout compatibility and thermal performance specifications. Ensure the procurement documentation explicitly references Diodes Incorporated as the source to avoid counterfeit components. Cross-reference the RoHS status and lead-free compliance details provided in the latest product release notes before finalizing orders.
Selection Notes
Select this component when a single-channel high-side switch with a 200 mA continuous output and 400 mA limit is required. The 110 mOhm on-resistance makes it suitable for low-voltage drop applications. Consider the U-DFN2018-6 package size constraints and the 2.7 V to 5.5 V operating voltage range during circuit design. Verify that the 50 us turn-on time aligns with system inrush current requirements.
Part Context
This part belongs to the AP2151 series of power switches from Diodes Incorporated. The series includes variants with different current ratings and packages, such as the AP2151AFM-7 which offers higher current capabilities. The AP21510FM-7 specifically targets applications requiring moderate current handling in a compact form factor, distinguishing itself from higher-current counterparts like the AP2151MPG-13.
Replacement Considerations
The AP2151AFM-7 serves as a verified alternative within the same series, offering higher current ratings (500 mA output, 800 mA limit) while maintaining similar voltage ranges and packaging styles. Designers should verify if the increased current capacity fits the application requirements and check for any differences in idle time or on-resistance values between the two parts.
