VNH3SP30TR-E 概述
An H-bridge motor driver is a four-switch power topology (two high-side, two low-side MOSFETs) that allows a DC motor to be driven in both directions from a single supply rail. The H-bridge sits in the broader power management hierarchy as a motor driver, an integrated power IC that combines the logic interface, gate drivers, protection features, and power FETs in one package. By integrating everything monolithically, the H-bridge IC replaces tens of discrete components and simplifies PCB layout for brushed DC and stepper motor control.
Key features of the VNH3SP30TR-E include PWM current control, parallel-mode operation for higher current loads, integrated charge pump for high-side gate drive, built-in thermal shutdown, cross-conduction protection, and a current sense output for closed-loop control. The device can drive two high-side switches in parallel or be configured as a full bridge. The MultiPowerSO-30 package provides a low thermal resistance path for dissipating the heat generated by the power FETs at high motor currents.
Typical applications include automotive DC motor control (window lifts, seat adjusters, sliding doors, tailgates, mirrors), industrial robotics and small pumps, HVAC damper actuators, and 24 V brushed servo systems. The wide supply range and integrated protection make it well suited for harsh 12 V/24 V automotive electrical environments with load-dump and cranking transients.
When designing with this part, derate the output current according to the PCB copper area used as a heatsink and ambient temperature; the MultiPowerSO-30 package relies on the PCB copper pour for thermal dissipation. Add adequate bulk decoupling on the supply rail and route the power ground separately from the logic ground. Consider the VNH2SP30 for lower-current applications or the VNH5019 for higher-current needs.

典型应用
VNH3SP30TR-E 适用于 6 应用s: Automotive Power Window Lifter, Electric Seat Adjuster Motor Drive, Sliding Door / Tailgate Motor Control, Side Mirror Adjustment Actuator, Industrial DC Brushed Motor Drive (24V), HVAC Damper Actuator.
Automotive Power Window Lifter
The VNH3SP30TR-E drives the brushed DC motor that raises and lowers a car window glass through an X-by-wire channel, replacing a relay-and-MOSFET discrete H-bridge. With 30 A continuous per switch and a 36 V supply ceiling, it absorbs the stall current of small window motors at end-of-travel stops without dropping out. Integrated thermal shutdown protects the IC if the window mechanism jams, while the analog current sense output lets the body controller detect mechanical obstruction and reverse the motor per FMVSS 118 pinch safety requirements. The MultiPowerSO-30 package's exposed thermal pad, soldered to a generous copper pour under the IC, dissipates the heat from bidirectional motor operation during summer temperatures. AEC-Q100 qualification lets automakers drop the part directly into a body control module.
推荐
Electric Seat Adjuster Motor Drive
The VNH3SP30TR-E runs the brushed DC motor that slides and reclines an automotive seat, delivering the high torque required to overcome seat rails loaded with passenger weight. The H-bridge's integrated charge pump drives the high-side N-channel MOSFETs fully enhanced, minimizing Rds(on) losses during continuous current draw under load. PWM input control lets the seat module apply soft-start acceleration for premium feel, while bidirectional current sense gives precise closed-loop position control when paired with a Hall sensor or potentiometer feedback. Operating from a 12 V automotive bus with 36 V load-dump tolerance, the VNH3SP30TR-E survives harsh cranking and jump-start scenarios that would destroy discrete designs. AEC-Q100 grade 0 temperature range supports under-seat mounting where summer cabin temperatures are extreme.
推荐
Sliding Door / Tailgate Motor Control
The VNH3SP30TR-E powers the heavy brushed DC motor that opens and closes minivan sliding doors or SUV tailgates, where motor current can spike to tens of amps during mechanical engagement. The fully integrated H-bridge replaces dozens of discrete power components on the body control module PCB, reducing BOM cost and assembly time while improving reliability. Parallel-mode operation of the two high-side drivers doubles the effective current handling for the largest motors in this class. The current sense output provides real-time feedback to the door control unit, enabling anti-pinch algorithms and end-of-travel soft-stop behavior. ST's automotive qualification and the MultiPowerSO-30 package's thermal robustness let the part sit directly behind the door trim panel without active cooling.
推荐
Side Mirror Adjustment Actuator
The VNH3SP30TR-E drives the small brushed DC motor that tilts and folds an exterior side mirror, providing the precise bidirectional control required for driver memory-position presets. Even though the mirror motor draws less current than a window or seat motor, the H-bridge IC's PWM speed control enables smooth mirror movement without overshoot or audible buzzing. The MultiPowerSO-30 package fits comfortably inside the door-mounted mirror module PCB, where space is constrained and ambient temperature can exceed 85 C in summer sun. The integrated thermal protection is essential for fault conditions such as a frozen mirror in winter ice that stalls the motor; the IC shuts down cleanly and recovers once the jam is cleared. AEC-Q100 grade 1 qualification supports the wide temperature swings seen in door-mounted automotive electronics.
推荐
Industrial DC Brushed Motor Drive (24V)
The VNH3SP30TR-E drives industrial brushed DC motors from 24 V factory DC buses, including small conveyor rollers, packaging machinery indexers, and automated guided vehicle (AGV) wheel motors. The 36 V absolute maximum comfortably tolerates 24 V nominal with regulated supply tolerance and inductive flyback spikes, eliminating the need for external TVS protection. Integrated cross-conduction protection prevents shoot-through that would otherwise burn out discrete MOSFET half-bridges, dramatically improving reliability in continuous-duty industrial applications. PWM input from an industrial PLC or motor controller enables variable speed without tachogenerator feedback, while the analog current sense output supports torque limiting and jam detection. The MultiPowerSO-30 package's industrial temperature range fits non-climate-controlled factory environments.
推荐
HVAC Damper Actuator
The VNH3SP30TR-E operates the brushed DC motor in an HVAC damper actuator that rotates louvers and blend doors to direct airflow in a vehicle climate control system. Despite the modest mechanical load, damper motors often run for long durations, demanding excellent thermal performance from the driver IC; the VNH3SP30TR-E's MultiPowerSO-30 thermal pad design sustains continuous operation without throttling. Bidirectional control with PWM speed input allows the HVAC controller to gently position the damper without overshoot, eliminating the audible thump that discrete relay switching produces. AEC-Q100 qualification supports the elevated temperatures inside an HVAC plenum near the heater core. The integrated H-bridge reduces the damper module's PCB size, allowing it to fit inside the compact actuator housing used by modern climate systems.

设计说明
The MultiPowerSO-30 package dissipates heat through the exposed thermal pad on the bottom of the IC. At 30 A continuous, the VNH3SP30TR-E can dissipate 5 W to 15 W depending on Rds(on) and switching frequency. Estimated: assuming 50 C/W theta_JA on a 1 oz copper pour of 6 square cm, junction temperature rise is 25 C/W x 10 W = 250 C above ambient, which exceeds the 150 C junction limit. Solder the thermal pad to a minimum 6 cm^2 copper pour on the top and bottom PCB layers, stitched with thermal vias, to keep junction temperature below 125 C at 85 C ambient.
Route the high-current OUTA and OUTB traces on the top and bottom layers with wide copper pours (at least 50 mil per ampere). Place a 100 nF ceramic decoupling capacitor plus a 100 uF electrolytic bulk capacitor as close as possible to the VS pins. Separate the power ground (high-current return) from the logic ground (CS, INA, INB return) and join them at a single point under the IC to prevent ground bounce from corrupting the current sense output. The CS pin is sensitive - keep its trace short and away from switching nodes.
Do not exceed 36 V on VS or the IC will suffer avalanche breakdown of the high-side charge pump. Do not parallel the two half-bridges without ensuring current sharing - use the dedicated parallel mode via ENA/ENB logic instead of tying outputs directly. Verify the IC is genuine; the STMicroelectronics community has documented counterfeit VNH3SP30 parts with polished-and-reprinted top markings in the gray market. Always purchase from authorized distributors. The -E suffix denotes automotive grade; -TR suffix denotes Tape & Reel packaging - the silicon is identical between -E and non-E suffix variants in this family.
Switching the H-bridge at high PWM frequencies (above 20 kHz) generates EMI that can couple into nearby analog circuits and the AM radio band. Add an RC snubber (100 ohm + 1 nF) across each power switch if PWM frequency exceeds 10 kHz, and place a common-mode choke on the motor leads. Keep the PWM trace short and away from sensitive analog signals; use a ground guard trace around the CS analog output to prevent capacitive coupling from the switching nodes.
