That current rating is the one that matters when a motor stalls or starts under load — the internal Power MOSFETs handle the surge without the package letting the smoke out first. The 16-VQFN-HR (3.5x5.5 mm) package with exposed pad sinks the heat into the PCB copper pour; the board layout determines the actual thermal limit, not the silicon alone. SPI interface provides register-based current regulation, fault reporting, and diagnostic readback — no external op-amps or comparators for current sensing. The 16-VQFN-HR package is a standard footprint; no special reflow profile beyond the JEDEC MSL level for the exposed-pad QFN family.","metaTitle":"TI DRV8145HQRXZRQ1 Half-Bridge Driver, 46 A","metaDescription":"Texas Instruments DRV8145HQRXZRQ1 automotive-grade half-bridge brushed DC motor driver. 46 A output, 4.5-35 V load, SPI interface, AEC-Q100.
