2.8A output and half-bridge topology
The two half-bridges let you drive a bipolar stepper motor in full-step or half-step modes, or run two independent brushed DC motors with forward/reverse control. The 2.8A per-bridge rating covers small pumps, fans, mirror actuators, and seat-position motors typical in automotive body electronics. The DMOS output stage keeps conduction losses low enough that a 16-pin QFN with exposed pad can dissipate the heat without an external heatsink in many designs.
Lifecycle and sourcing reality
The DRV8801AQRMJRQ1 is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy schedule is in effect. For dual-sourcing consideration, the DRV8811PWPR is a functionally similar part with four half-bridges and a lower 1.9A output, but it is a general-purpose device without AEC-Q100 qualification — not a direct automotive drop-in.
