Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration and reel specifications. Confirm that the component meets the required automotive quality standards and functional safety levels for your target application environment. Cross-reference the datasheet version to validate all electrical parameters against your design requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring robust gate driving capabilities in 24V or 48V automotive architectures. It serves as a suitable interface between external microcontrollers and power MOSFETs. Consider its integrated diagnostic features if system monitoring is critical. Ensure compatibility with existing software drivers and configuration tools provided by the manufacturer for efficient integration.

Part Context

This part belongs to the MOTIX series of motor gate driver integrated circuits. It complements Infineon's motor control SoC solutions like the TLE987x and TLE989x families. The device is engineered to facilitate the transition from 12V to higher voltage automotive systems while maintaining software and hardware design reuse.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Designers should evaluate other MOTIX series devices such as the TLE9180D or TLE9183QK based on voltage domain and safety integrity level requirements. Verify pinout and functional compatibility when considering alternative components.
