DRV8350HRTVR

DRV8350HRTVR is TI’s three-phase brushless DC motor driver with integrated six N‑channel MOSFETs. It drives a BLDC or PMSM motor from a DC bus using simple gate inputs or PWM for automatic commutation. Key features: three half‑bridges with dead time, programmable current limit and current regulation, options for braking and coast, and protection with fault reporting. Protections include undervoltage, overcurrent, overtemperature, and short-to-ground/overvoltage. It’s packaged in the HRTVR variant (HTSSOP family) for compact boards. Typical applications include robotics, cooling/fan assemblies, and small automation drives. For exact specs (V_BUS range, peak/continuous current, sense resistor needs, and fault codes), consult the TI datasheet and reference designs.

Drop-in exact equivalents for DRV8350HRTVR do not exist. It is TI’s 3-phase BLDC motor driver. Closest substitutes within TI’s lineup: DRV83xx family such as DRV8301, DRV8305, DRV8323, DRV8313. Other vendors offer similar parts: Allegro A390x, ST L623x/L698x, Trinamic (TMC) series. Exact choice depends on your specs (voltage, current, sense, packaging).

Here are key features of the DRV8350HRTVR (3-phase BLDC motor driver with gate drive):
- Three high-current half-bridges for BLDC/PMSM motors; integrated gate drivers.
- Motor supply (Vs) range: 6–28 V; bootstrap high-side drive.
- Peak output current up to 43 A per bridge; ~14 A RMS continuous per phase (with adequate cooling).
- Programmable current regulation via external sense resistor (RSENSE) for motor current control.
- PWM-compatible inputs for three phases with built-in dead time; supports safe commutation.
- Protection and diagnostics: UVLO, overvoltage, overcurrent, overtemperature; fault/status reporting.
- Fault and status pins for monitoring (diagnostics).
- Thermal management: HTSSOP-28 package with exposed pad; DRV8350HRTVR in reel packaging (HRTVR).
- Applications: BLDC/PMSM motors in automotive, industrial, robotics, HVAC, and similar systems.
Note: Bootstrapped gate drive and external components required (sense resistor, bootstrap caps, etc.).
