Overview
The AP22800HB-7 is a single-channel high-side load switch manufactured by Diodes Incorporated. It supports an input voltage range of 1.5 V to 5.5 V and delivers a maximum output current of 4 A. The device features a typical on-resistance of 19 mOhms and a maximum on-resistance of 21 mOhms. It operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum turn-on time of 90 µs and a maximum turn-off time of 21 µs. The component is housed in an 8-pin U-DFN2116 package with an exposed pad for thermal management.
Feature Summary
- Integrates controlled slew rate functionality to minimize inrush current during power-up sequences.
- Includes under-voltage lockout (UVLO) circuitry to ensure stable operation at low supply voltages.
- Features a non-inverted open/switch interface for straightforward logic control integration.
Applications
- Power distribution networks in portable consumer electronics
- Load switching for peripheral devices in embedded systems
- Voltage regulation stages requiring controlled ramp-up times
Procurement Notes
Verify the specific suffix HB-7 against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad specifications. Ensure that the U-DFN2116 footprint matches the design layout requirements. Confirm RoHS compliance status directly from the latest production documentation before finalizing procurement orders.
Selection Notes
Select this component when a 4 A current capacity is required within a 5.5 V system limit. The low on-resistance makes it suitable for applications prioritizing efficiency over minimal quiescent current. Consider the 90 µs turn-on time for timing-sensitive designs where rapid switching is not critical.
Part Context
This part belongs to the AP2280 series of power switches from Diodes Incorporated. The series offers various current ratings and package options. The AP22800HB-7 specifically targets high-current applications requiring robust protection features and compact surface-mount packaging for modern electronic assemblies.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official cross-reference documentation for verified alternatives.
