Overview
The AP22652FDZ-7 is a precision load switch IC from Diodes Incorporated, designed for power distribution applications. It operates within a supply voltage range of 3 V to 5.5 V and features an N-channel output capable of delivering up to 2.1 A. The device incorporates adjustable current limiting at 700 mA, with a maximum on-resistance of 90 mOhms. It includes comprehensive fault protection mechanisms such as over-temperature, short-circuit, and under-voltage lockout (UVLO). The component is housed in a compact SOT-26 package and supports surface-mount installation across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates precision current limiting with adjustable threshold capabilities for robust load protection
- Provides high-side switching functionality using an N-channel configuration for efficient power management
- Includes built-in thermal shutdown and under-voltage lockout to ensure safe operation during fault conditions
Applications
- Portable electronic devices requiring precise power sequencing and load management
- USB peripheral power switching and distribution circuits
- Embedded systems needing protected power rails for sensitive components
Procurement Notes
Verify the specific suffix FDZ against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure compatibility with required manufacturing processes and quality standards before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when precise current limiting and high-side switching are required for loads up to 2.1 A. Consider the SOT-26 package size for space-constrained designs. Evaluate the 90 mOhm on-resistance against system efficiency requirements and thermal dissipation capabilities within the specified operating temperature range.
Part Context
This part belongs to the AP22652 series of load switches, which are optimized for power distribution in portable electronics. The series offers various configurations to meet different current and packaging needs. The AP22652FDZ-7 specifically targets applications requiring reliable protection and efficient power control in compact form factors.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the AP22652 family or similar load switch products from Diodes Incorporated. Verify pin compatibility and electrical parameters before replacing.
