AEC-Q100 grade and the thermal envelope that governs deployment
The TB9057FG is an automotive H-bridge pre-driver qualified to AEC-Q100 — the stress and reliability screening required by Tier-1 and OEM PPAP documentation. An OEM auditor will require the full qualification report to confirm the grade before signing off a safety-critical or high-temperature zone.
Motor type support and supply rail requirements
The TB9057FG drives brushed DC motors via its H-bridge pre-driver output configuration and bipolar stepper motors through the same bridge topology, with a PWM interface that accepts logic-level control signals. The supply voltage range of 5V to 21V accommodates both regulated 5V and unregulated automotive battery rails (12V nominal, 9V-16V operating with cold-crank dips and load-dump transients within the abs-max rating).
