What this part is and where it fits
The Texas Instruments DRV8801QRTYRQ1 is a fully integrated DMOS motor driver that combines control logic and power stage in a single 16-QFN package. It drives one brushed DC motor or one bipolar stepper motor using two half bridges, with a continuous output current rating of 2.8 A. The part operates from a single 8 V to 38 V supply rail, covering both the logic and motor supply. It is qualified to AEC-Q100, making it suitable for automotive under-hood and chassis-domain applications such as HVAC actuators, headlamp leveling, and transmission solenoids.
2.8 A output — sizing the load budget
The 2.8 A continuous rating is the per-device limit, not per half-bridge. For a brushed DC motor, both half bridges can be paralleled to increase current handling, but the total package dissipation still governs. The 16-QFN with exposed pad needs a good thermal via pattern to the ground plane to keep junction temperature below 150°C at full load. For stepper applications, each phase sees the full 2.8 A, so winding resistance and duty cycle must be checked against the thermal budget.
Automotive temperature range — what it covers
The junction temperature range is -40°C to 150°C. The part is rated for continuous operation at 150°C junction.
Lifecycle and sourcing posture
The DRV8801QRTYRQ1 is listed as Active in production. There is no last-time-buy notice or NRND flag. The part is ROHS3 compliant. For BOM planning, this means no imminent obsolescence risk. The part is also available in Cut Tape (CT) for prototyping, though production volumes typically order on Tape & Reel (TR).
