MC33886VWR2 Visão geral
An H-Bridge motor driver is a four-switch power topology that allows a DC motor or solenoid to be driven in both directions (forward and reverse) from a single supply rail. The MC33886 integrates all four switches plus the high-side gate-drive charge pump, so designers do not need external transistors or bootstrap circuits. This makes the part a member of the broader power management IC family, sitting between discrete MOSFET drivers and fully integrated multi-axis motion controllers.
Key features include 5 A continuous output current, a 5 V to 40 V operating supply range, CMOS/parallel logic inputs with built-in charge pump, low on-state resistance, internal thermal protection, and an exposed-pad HSOP-20 package that dissipates up to approximately 2 W without a heatsink. According to the Freescale/NXP datasheet, the device is ideal for fractional-horsepower brushed DC motors, bi-directional solenoids, and small stepper-style loads.
Architecture-wise the part uses four N-channel power MOSFETs in an H configuration driven by an internal charge pump that generates the gate-boost voltage for the high-side FETs. Logic inputs (IN1, IN2, EN) feed a TTL-compatible interface that sets forward, reverse, brake-low, or high-impedance modes. The integration removes the need for external gate drivers and simplifies PWM speed control up to the part's maximum switching frequency.
Typical applications include automotive HVAC flaps and door lock actuators, industrial valve control, small robotic drive stages, solenoid drivers in white goods, and battery-powered tools. The wide 5 V to 40 V supply window also allows direct connection to 12 V and 24 V vehicle buses without pre-regulation.
Designers should keep the thermal pad soldered to a continuous copper pour to keep junction temperature within ratings, and place a low-ESR decoupling capacitor close to V+. Always respect the absolute maximum supply voltage (40 V) and use PWM frequencies below the specified maximum to avoid shoot-through losses.

MC33886VWR2 Área de Operação Segura (estimated from HSOP-20 exposed pad)
Aplicações típicas
MC33886VWR2 é adequado para 6 aplicaçãos: Automotive HVAC Flap Actuators, Power Door Lock and Mirror Actuators, Industrial Solenoid and Valve Drivers, Small Robotic Drive Wheels, Battery-Powered Cordless Tools, White Goods and Appliance Actuators.
Automotive HVAC Flap Actuators
The MC33886VWR2 is well matched to automotive HVAC mode and blend-door actuators that drive small brushed DC gear motors from a 12 V bus. Its 5 V to 40 V supply range covers the 12 V nominal with full load-dump margin, and the 5 A continuous current handles stall currents of fractional-horsepower gear motors typical in HVAC modules. The integrated charge pump eliminates the external bootstrap components normally needed for high-side N-channel FETs, allowing a compact PCB that fits inside the actuator housing. Designers should add a TVS diode for ISO 7637-2 transient immunity and ensure the exposed pad has at least 1 square inch of copper to dissipate the 5 W worst-case dissipation at stall.
Recomendado
Power Door Lock and Mirror Actuators
Central locking and power mirror actuators in vehicles draw 2 A to 4 A peak current when moving a stalled mechanism, which the MC33886VWR2 handles comfortably within its 5 A rating. Bi-directional control via IN1/IN2 allows the same driver to handle lock/unlock and mirror-fold/unfold functions. The CMOS/parallel logic interface connects directly to a body control module without level shifters, reducing wiring and BOM. Operating temperature of -40 C to +125 C matches under-hood and door-module thermal environments, and the H-Bridge topology supports the dynamic braking mode used to stop the actuator precisely at the requested position.
Recomendado
Industrial Solenoid and Valve Drivers
The MC33886VWR2 drives 24 V industrial solenoid valves and latching actuators that require bi-directional current or pulse control. Its 5 V to 40 V supply range accepts 24 V industrial bus rails directly, and the 5 A continuous rating covers most process-control solenoid sizes. The internal thermal shutdown protects the IC if the solenoid sticks in the energized state, while parallel logic inputs simplify interface to PLC discrete-output modules. The exposed-pad HSOP-20 package mounts on a small DIN-rail or backplane PCB without a heatsink, and the integrated gate drive means no external charge pump capacitors are needed beyond the V+ bypass.
Recomendado
Small Robotic Drive Wheels
Educational and small-payload robotic platforms use brushed DC gear motors in the 1 A to 5 A range, which the MC33886VWR2 can drive bidirectionally from a single-cell Li-ion (12 V nominal with boost) or 4-cell Li-ion pack (14.8 V nominal). The integrated H-Bridge eliminates four discrete MOSFETs, two gate drivers, and a charge pump that would otherwise crowd a small robot chassis PCB. PWM speed control up to the part's maximum frequency allows closed-loop wheel-velocity regulation with an external encoder. The exposed pad on the HSOP package simplifies thermal dissipation when the robot pushes stall loads.
Recomendado
Battery-Powered Cordless Tools
Low-voltage cordless tools such as screwdrivers and pruning shears use brushed DC motors drawing 3 A to 5 A from a 12 V or 18 V battery pack. The MC33886VWR2 handles both forward and reverse drive modes for screw-in/screw-out operation, and its brake-low mode (via IN1/IN2 logic) provides fast motor stop without external braking resistors. Operating efficiency from low RDS(ON) MOSFETs extends battery runtime compared to discrete bipolar H-bridge designs. The HSOP-20 exposed-pad package is small enough for handheld-tool enclosures while still dissipating continuous current when mounted on adequate copper.
Recomendado
White Goods and Appliance Actuators
Washing-machine dispensers, dishwasher detergent drawers, and refrigerator water-valve actuators all use small brushed DC motors or solenoids operating from 12 V to 24 V supplies. The MC33886VWR2 fits these loads with its 5 A capability and 40 V maximum, simplifying the appliance control board by replacing discrete relay-plus-MOSFET circuits with a single IC. Internal protection (thermal shutdown and undervoltage lockout) improves appliance reliability by detecting stalled actuators without external circuitry. The CMOS/parallel interface connects directly to the appliance microcontroller, reducing wiring complexity and assembly cost.

Notas de projeto
Estimated: at V+ = 12 V, motor current 5 A, and 50 percent PWM duty, dissipation in the H-Bridge is roughly 12 V * 5 A * 0.5 = 3 W worst-case assuming 100 milliohm RDS(ON). The 20-HSOP exposed-pad package has theta_JA around 30 C/W on 1 sq inch of 2-oz copper, giving a 90 C junction rise at 3 W. For continuous 5 A operation above ambient 60 C, add a heatsink or expand the exposed-pad copper pour to 2 sq inches to drop theta_JA below 20 C/W. Mount the thermal pad with sufficient solder paste coverage to avoid voids which would otherwise increase the effective junction-to-ambient resistance.
Place a 100 nF ceramic decoupling capacitor as close as possible to the V+ pin and a bulk aluminum or tantalum capacitor of at least 100 uF on the same supply trace within 1 cm of the package. Use wide copper pours (at least 2 mm or 80 mils wide) for V+, OUT1, OUT2, and GND to minimize voltage transients at high di/dt. The exposed thermal pad must be soldered to a continuous copper plane connected to GND with multiple thermal vias to the inner layers for effective heat spreading.
Do not exceed the 40 V absolute maximum on V+; load-dump transients on 12 V automotive supplies can reach 35 V to 40 V, so add a TVS clamp diode of 33 V or 36 V working voltage between V+ and GND. Do not float the EN pin - it must be driven high or low to a defined logic level. Avoid connecting the motor leads between OUT1 and OUT2 with the IC powered off, as back-EMF can exceed the absolute maximum ratings. Always check PWM frequency against the motor inductance to prevent the H-Bridge from operating in discontinuous-current mode beyond rated SOA.
