Typical Applications
DRV3255-Q1 is suitable for 6 applications: 48-V Belt Starter Generator (BSG), Mild-Hybrid Motor Generators (MHEV), E-Turbo and E-Compressor Drives, 48-V Traction Accessories and Pumps, Functional Safety Motor Control Systems, 48-V Test and Validation Bench Systems.
48-V Belt Starter Generator (BSG)
The DRV3255-Q1 fits 48-V BSG drives because its 3.5-A/4.5-A peak gate drive currents switch large parallel MOSFET arrays at the 350-A class output levels typical of BSG systems, per TI application report SLVAF39A. The GDU sits between the traction MCU and the three-phase MOSFET bridge, using its bootstrap architecture to drive high-side devices while integrated Active Short Circuit handles fault response without external shorting transistors. The 90-V transient rating covers 48-V bus overvoltage events common in mild-hybrid operation.
Recommended
Mild-Hybrid Motor Generators (MHEV)
MHEV motor generator drives require functional-safety-ready components; the DRV3255-Q1 provides wide monitoring, diagnostics, and protection plus 75-V digital I/O absolute maximum ratings protecting against 12-V supply overvoltage. Its configurable high/low-side Active Short Circuit rapidly de-energizes the machine during faults, a key safety mechanism for 48-V e-machine drives. The 90-V MOSFET transient support and AEC-Q100 qualification make it suitable for production MHEV platforms requiring robust 48-V power-stage control.
Recommended
E-Turbo and E-Compressor Drives
48-V e-turbo and e-compressor motors run at high speed and demand fast, clean gate switching; the DRV3255-Q1's 3.5-A source / 4.5-A sink currents minimize MOSFET switching losses at the high PWM frequencies these drives use. The bootstrap high-side architecture keeps the solution compact for the tight packaging of compressor housings. Integrated diagnostics detect gate faults early, protecting the motor where service access is difficult, while the configurable ASC function safely shorts phases during spin-down fault events.
Recommended
48-V Traction Accessories and Pumps
High-power 48-V auxiliary drives (oil pumps, coolant pumps, HVAC blowers) benefit from the DRV3255-Q1's integrated protection suite, which reduces external component count versus discrete gate driver designs. The 90-V transient rating protects against load transients on 48-V auxiliary rails, and the Active Short Circuit function provides safe torque-off behavior without additional shorting relays or transistors. AEC-Q100 qualification supports under-hood placement where ambient temperatures and vibration exceed consumer-grade limits.
Recommended
Functional Safety Motor Control Systems
For drives targeting functional-safety requirements, the DRV3255-Q1 offers layered monitoring and diagnostics supporting system-level safety concepts, plus the industry-first integrated high- and low-side active shorting that removes external ASC transistors and their failure modes from the safety analysis. Digital I/O pins withstand 75-V absolute maximum, protecting the diagnostic interface during supply faults. These mechanisms, combined with an AEC-Q100-qualified process, give safety engineers documented device-level fault coverage for 48-V drive architectures.
Recommended
48-V Test and Validation Bench Systems
The DRV3255-Q1 is used in 48-V power-stage development benches and hardware-in-the-loop validation rigs where designers characterize MOSFET switching and ASC behavior. Its rich diagnostic reporting exposes gate-drive fault data over the SPI interface, accelerating root-cause analysis during bring-up. TI's parallel-MOSFET reference (SLVAF39A) gives a validated starting point for scaling the bench design toward 350-A outputs, and EVM availability from TI shortens the path from schematic to first spin

Key Differentiators
- Industry-first integrated high/low-side Active Short Circuit (vs DRV8353SRTAR-Q1)
- 90-V transient overvoltage support for 48-V systems (vs DRV8353SRTAR-Q1)
- Very high gate drive for parallel MOSFETs (vs DRV3251-Q1 (lower-feature family members))
Design Notes
With 3.5-A/4.5-A peak gate currents, gate loop inductance dominates switching performance. Place the DRV3255-Q1 as close as possible to the MOSFET gate resistors, route GHx/GLx traces as tight paired loops over ground, and use individual gate resistors per parallel MOSFET per TI SLVAF39A. Keep bootstrap capacitors within 5 mm of the HBx pins and reserve copper for the 64-pin HTQFP thermal pad.
Size bootstrap capacitors against total gate charge of the parallel MOSFET array; insufficient bootstrap energy causes high-side UVLO glitches under high-duty-cycle operation. Decouple VGLS/VCP per datasheet recommendations and verify the 90-V transient clamp headroom against your worst-case 48-V bus ring waveform, including load dump, before finalizing the snubber design.
Digital I/O pins withstand 75 V absolute maximum - this protects against 12-V supply overvoltage but does not make the pins level translators for higher domains. Configure the Active Short Circuit pin strapping to match your safety concept before first power-up: an incorrect ASC configuration can short phases at startup. Validate SPI diagnostics timing against the datasheet before enabling fault-based shutdown in software.
