For a brushed DC motor, that translates to stall-current handling on a 12V or 24V rail without immediate thermal shutdown. ## Automotive temperature range and grade Rated for -40°C to 125°C ambient, this part is suitable for under-hood or chassis-mounted modules. The Automotive grade means the part has passed extended reliability stress tests. ## PWM and SPI — what the interface choices buy you PWM input is the straightforward way to control motor speed or position from an ECU or MCU timer output. The SPI port adds configurability: you can set the current-regulation level, adjust the dead time, read back fault flags (overcurrent, overtemperature, undervoltage), and change the drive mode without changing the hardware. That SPI diagnostic channel is what separates this driver from a plain PWM-input FET driver — it lets the system controller log faults and decide whether to retry or shut down, which matters for functional-safety architectures. ## Package and mounting — wettable flank matters The 14-VFQFN package with wettable flank terminals is a surface-mount part designed for automated optical inspection (AOI). The wettable flank means the solder fillet climbs the side of the terminal, so a vision system can verify the joint — no X-ray required. That is a production-line advantage for automotive tier-1s that need process control on every board. The 3x4.5mm footprint is compact enough for space-constrained ECU layouts. ## Lifecycle and sourcing reality TI lists the DRV8143SQRXYRQ1 as Active with ROHS3 compliance. That means it is a safe choice for new designs and production ramps — no forced redesign in the next few years.","metaTitle":"DRV8143SQRXYRQ1 Automotive Half-Bridge Driver, 20A, 4.5-35V","metaDescription":"TI DRV8143SQRXYRQ1 automotive 40V, 20A half-bridge driver for brushed DC and bipolar stepper motors.
