Procurement Notes

Verify the specific ordering suffix matches the required package configuration, as variations exist between tape-and-reel and tube formats. Confirm AEC-Q100 qualification status aligns with project requirements. Ensure the 24-bit SPI interface compatibility is validated against the host controller. Check for any product change notifications regarding manufacturing updates. Validate that the QFN-32 package dimensions fit the designated PCB footprint constraints.

Selection Notes

Select this component when four independent high-side outputs with detailed diagnostic feedback are required. The integrated 10-bit ADC enables precise current monitoring without external sensing components. Consider the device if compliance with LV124 revision 2013 standards is mandatory for cold cranking scenarios. The built-in PWM engine simplifies design for applications requiring independent frequency and phase control per channel. Evaluate the thermal shutdown configuration options to match system safety protocols.
