DRV8376HQNLGRQ1 概要
A motor driver is an integrated circuit that translates low-power control signals from a microcontroller into the high-current, high-voltage signals needed to drive a motor. The DRV8376-Q1 belongs to the gate driver and integrated power stage family, positioned between the MCU and the three-phase motor in the power electronics hierarchy. It provides the power amplification, current feedback, and protection layers required in modern automotive and industrial motion systems.
Key features include integrated current sensing that eliminates external sense resistors, reducing BOM cost and board area. The device supports PWM control with a highly configurable interface through hardware pins or registers, allowing flexible current limiting, slew-rate control, and fault response tuning. Protection features include overcurrent, overtemperature, and undervoltage lockout with fault reporting, safeguarding the device, motor, and system.
The DRV8376-Q1 uses an NMOS power-stage architecture in a three-phase bridge configuration. The low 400 mOhm RDS(on) minimizes conduction losses, improving thermal performance and efficiency. The integrated sense-FET current sensing provides accurate current feedback without the power loss of external shunts, enabling precise torque control and stall detection in FOC and trapezoidal control schemes.
Typical applications include automotive BLDC motors such as electric power steering (EPS), engine cooling fans, oil pumps, and fuel pumps. AEC-Q100 qualification and the 4.5V to 65V input range suit both 12V and 24V automotive systems, as well as industrial drives and robotics requiring integrated sensing.
When designing with this device, ensure proper PCB layout with adequate copper area on the VQFN exposed pad for thermal dissipation, and place decoupling capacitors close to the power pins. Calibrate the current-sense gain setting for accurate torque control.

主な用途
DRV8376HQNLGRQ1 の用途: 6 件s: Electric Power Steering (EPS), Engine Cooling Fans, Automotive Oil and Fuel Pumps, Industrial BLDC Drives and Robotics, 24V Automotive and Commercial Vehicle Systems, Drones and UAV Propulsion.
Electric Power Steering (EPS)
The DRV8376HQNLGRQ1 fits EPS assist motors where AEC-Q100 qualification, 70V transient tolerance, and integrated current sensing are mandatory. Its 400 mOhm RDS(on) and 4A peak capability support the assist torque demands of 12V column- and rack-assist EPS systems, while the integrated sense-FET current feedback feeds the torque-control loop without external shunt resistors, saving BOM cost and layout area. Placed between the MCU gate-control outputs and the three-phase motor, the device provides PWM drive plus overcurrent and overtemperature protection; the main trade-off is that continuous dissipation of I^2R losses requires a well-designed exposed-pad thermal layout.
おすすめ
Engine Cooling Fans
Automotive cooling fan motors benefit from the DRV8376HQNLGRQ1's wide 4.5V to 65V supply range, which absorbs load-dump and cranking transients up to the 70V absolute maximum. The integrated current sensing enables stall detection and diagnostic reporting to the body controller, while the low 400 mOhm bridge resistance reduces heat generation in the sealed under-hood environment. Configurable slew-rate control reduces EMI from long motor lead harnesses. Unlike discrete gate-driver solutions, this integrated power stage shortens design time; the consideration is that 4A peak current defines the upper limit of fan motor size supported.
おすすめ
Automotive Oil and Fuel Pumps
In-tank fuel pumps and engine oil pumps use the DRV8376HQNLGRQ1 for its integrated protection suite: overcurrent, overtemperature, and undervoltage lockout with fault reporting suited to functional-safety-aware pump designs. The 65V maximum supply and Q1 automotive qualification cover 12V and 24V pump platforms, and the integrated current sensing supports dry-run and jam detection without external shunts that would add in-tank reliability concerns. PWM control allows flow-rate modulation for energy-efficient pumping. Designers should account for the 400 mOhm RDS(on) conduction loss when the pump runs at continuous high duty cycles.
おすすめ
Industrial BLDC Drives and Robotics
For industrial servos, gimbal drives, and robotic joints requiring compact high-power three-phase drive, the DRV8376HQNLGRQ1's integrated 4A-peak power stage with current feedback simplifies the drive stage versus discrete MOSFET solutions. The 400 mOhm RDS(on) keeps conduction losses low in the 6x5mm VQFN, fitting space-constrained joint modules, while PWM-configurable control supports both trapezoidal and field-oriented control from any MCU. Integrated protection simplifies safety design. For currents beyond 4A continuous, a gate-driver solution such as DRV8353 with external FETs is the appropriate escalation path.
おすすめ
24V Automotive and Commercial Vehicle Systems
Trucks, buses, and commercial vehicles use 24V rails where transient levels exceed typical 40V-class drivers; the DRV8376HQNLGRQ1's 65V operating / 70V absolute maximum rating provides the required headroom. The same 400 mOhm, 4A-peak power stage and integrated sensing used in 12V designs carry over directly, enabling one driver platform across vehicle lines. The Q1 qualification supports commercial-vehicle quality requirements, and configurable fault response adapts to heavy-duty protection strategies. Verify load-dump clamp levels in the specific vehicle platform to confirm margin against the 70V absolute maximum.
おすすめ
Drones and UAV Propulsion
High-voltage UAV BLDC ESCs operating from 6S-12S lithium packs (22V to 50V) fit inside the DRV8376HQNLGRQ1's 65V envelope, and the integrated current sensing enables per-phase current limiting critical for motor protection during aggressive maneuvers. The 400 mOhm bridge and 4A peak output suit small-to-medium multirotor motors, and the compact 6x5mm VQFN keeps ESC mass and footprint low. Slew-rate configurability suppresses switching EMI near sensitive receivers. Compared with discrete ESC designs, integration reduces component count but defines the 4A peak ceiling on propeller size.

設計ノート
The 28-VQFN 6x5mm exposed pad is the primary thermal path. At 4A peak with 400 mOhm total RDS(on), instantaneous conduction loss reaches ~6.4W; continuous dissipation depends on your PWM duty cycle. Solder the exposed pad to at least 1 square inch of 2oz copper with an array of thermal vias, per TI layout guidelines in the DRV8376-Q1 datasheet. Run a thermal simulation at your maximum continuous current before finalizing the PCB.
Place ceramic decoupling capacitors (per TI datasheet recommendation) directly across VM to GND as close to the power pins as possible to suppress parasitic inductance spikes during PWM switching. Keep the high-current three-phase loops (VM-high side-motor-low side-GND) as small as possible to limit radiated EMI. Route the sensitive current-sense/config traces away from the motor phase nodes.
Never exceed the 70V absolute maximum - 24V commercial vehicle platforms can see load-dump transients above this without clamping. Configure the current-sense gain correctly for your motor's continuous current range to get accurate torque feedback; the integrated sensing removes shunts but does not remove the calibration step. Enable the undervoltage lockout threshold appropriate to your battery system to prevent drive at brownout.
