Procurement Notes

Verify that the specific part number suffix matches the required packaging configuration, as variations may exist between tape-and-reel quantities. Confirm AEC-Q100 qualification status is explicitly stated in the official datasheet for the specific batch or revision being procured. Ensure the supplier provides traceability documentation consistent with automotive grade requirements. Cross-reference the manufacturer's latest release notes to confirm no obsolescence notices apply to this specific variant.

Selection Notes

Select this component when a linear topology is preferred for simplicity in automotive LED control applications requiring up to 750 mA. The integrated PWM dimming capability eliminates the need for external microcontrollers for basic brightness control. Consider the thermal dissipation characteristics of the TSSOP-16EP package relative to the expected power loss at the target current and input voltage levels. Ensure the application voltage does not exceed the 55 V maximum rating.

Part Context

This component belongs to the AL5871Q series of automotive-grade LED drivers from Diodes Incorporated. The series is designed specifically for robust performance in vehicle environments. The 'T' indicates the TSSOP-16EP package type, while '13' typically denotes the tape and reel quantity. It serves as a dedicated solution for driving LEDs where precise current regulation and dimming are critical.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Diodes Incorporated AL5871 family that may offer different current ratings or package options. Verify that any substitute maintains the AEC-Q100 qualification if automotive compliance is mandatory. Ensure the replacement supports the required 200 kHz to 1 MHz PWM frequency range.
