Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before integration into new products. Confirm package details correspond to the PowerSSO-36 variant associated with the XPTR suffix. Ensure compatibility with existing design architectures due to the discontinued status of this specific part number.

Selection Notes

Select this component for designs requiring integrated bridge control with diagnostic capabilities via SPI. Consider the 6 V to 28 V operating range and 30 kHz PWM limit. Evaluate the need for external MOSFETs and thermal sensor integration, as the driver relies on these external components for power handling and temperature monitoring.
