MC33887DWBR2 Descripción general
An H-Bridge motor driver is a type of power IC that uses four switching MOSFETs in an H-configuration to drive a DC motor bidirectionally from a single supply. MC33887DWBR2 occupies the category of motor drivers within the broader power management IC hierarchy (H-Bridge -> motor driver -> power management IC -> semiconductor). The integrated current feedback eliminates the need for an external sense resistor, simplifying closed-loop torque or speed control loops in motor control systems.
Key features of the MC33887DWBR2 include 5.0 A continuous load current capability, integrated charge pump for gate drive, PWM frequency support up to 20 kHz, and load current feedback output for real-time monitoring. The part provides internal logic-level translation, active-low and active-high control inputs, and built-in protection against overcurrent, overtemperature, and undervoltage lockout conditions per manufacturer datasheet literature.
The architecture uses four N-channel MOSFETs in a classic H-Bridge topology with cross-conduction lockout (dead time) generated internally. The charge pump provides the gate-to-source voltage required to keep the high-side switches in enhancement mode at low VIN, supporting low-drop operation down to 5 V across the full VDS span. Current feedback is implemented by sampling on-chip current with a transconductance amplifier that sources a ground-referenced analog voltage proportional to load current.
Typical applications include automotive HVAC flap actuators, throttle body control, headlamp beam levelling motors, robotics DC servo drives, and battery-powered small DC motor drives in industrial automation. The load feedback feature makes it especially well suited where the MCU needs real-time torque/load information for PID control. Compared to discrete MOSFET H-bridges, the MC33887DWBR2 reduces PCB area, BOM count, and design time significantly in production motor-control assemblies.
When designing with this IC, pay close attention to thermal layout: at 5 A continuous load and 12 V supply, dissipation in the H-bridge can reach several watts, so a copper thermal land beneath the exposed pad is required for reliability. Also confirm PWM dead time behaviour matches the motor's mechanical time constant to avoid audible noise or torque ripple.

Aplicaciones típicas
MC33887DWBR2 es adecuado para 6 aplicacións: Automotive HVAC Flap Actuator Drive, Electronic Throttle Body Control, Headlamp Beam Levelling Motor Drive, Robotics Small DC Servo Motor Driver, Industrial Conveyor Drive Module, Battery-Powered Small DC Motor Drive.
Automotive HVAC Flap Actuator Drive
The MC33887DWBR2 is widely used in automotive HVAC blend-door and mode-door flap actuators where 12 V brushed DC gear motors must be driven bidirectionally with closed-loop position feedback. Its 5 V to 28 V VDD range covers the 12 V automotive bus including crank transients, while the integrated load current feedback output (FB) allows the HVAC ECU to detect stall or obstruction by sensing motor current without an external sense resistor. The 54-SOIC exposed pad dissipates continuous drive losses to PCB copper. Compared to discrete MOSFET H-bridges, MC33887DWBR2 reduces BOM and ECU size, critical for under-dash modules where PCB real estate is limited.

Electronic Throttle Body Control
In electronic throttle body (ETB) systems, the MC33887DWBR2 drives the brushed DC motor that repositions the throttle plate, with the load current feedback providing torque-allowance diagnostics. The internal charge pump keeps the high-side N-MOSFETs fully enhanced across the entire 5-28 V VDD range, ensuring low-loss PWM switching during closed-loop idle-air and pedal-follower modes. The overcurrent and overtemperature shutdown protects the throttle from stall-induced damage, a critical regulatory requirement in modern drive-by-wire designs. PCB layout places the 54-SOIC exposed pad on a 1+ square-inch copper land for thermal dissipation under high duty cycle.

Headlamp Beam Levelling Motor Drive
Adaptive front-lighting systems use the MC33887DWBR2 to drive the small brushed DC gear motor inside each headlamp beam-level actuator. The 5 A continuous current is more than adequate for the 100-500 mA typical motor load, and the integrated load current feedback detects motor stall when the actuator reaches its mechanical endstop - enabling precise headlamp aim without a separate endstop switch. The 54-SOIC package is small enough to fit in the headlamp housing, and the exposed pad supports the brief inrush current during actuator travel. IN1/IN2 logic inputs connect directly to the BCM's 5 V GPIO without level shifters.
Recomendado
Robotics Small DC Servo Motor Driver
Robotics and hobby servo projects use the MC33887DWBR2 to drive 12-24 V brushed DC gear-motors up to 5 A continuous. The integrated load current output feeds a microcontroller ADC that implements torque or speed PID loops for educational and industrial robotic arms. With 20 kHz PWM support, the part produces no audible motor whine in noise-sensitive applications, ideal for indoor robots. The 54-SOIC exposed pad is large enough for a 0.5 square-inch copper pour, accommodating a single motor without forced-air cooling. Compared to integrated H-bridge driver boards, MC33887DWBR2 enables custom PCB integration at lower per-unit cost.
Recomendado
Industrial Conveyor Drive Module
For industrial conveyor belts using low-voltage brushed DC motors, the MC33887DWBR2 provides bidirectional control with internal current monitoring for jam detection. The 5.0 V to 28 V supply range accepts 24 V industrial bus rails, allowing motor reverse and brake modes via IN1/IN2 logic inputs. Integrated fault protection (overcurrent, overtemperature, undervoltage) prevents costly conveyor downtime by autonomously shutting down on jam, while the exposed-pad 54-SOIC package lands on conveyor-side PCB copper for 24x7 duty cycle operation. Engineers typically pair MC33887DWBR2 with a PLC-side MCU implementing Modbus or EtherCAT control.
Recomendado
Battery-Powered Small DC Motor Drive
Battery-powered tools and consumer appliances benefit from the MC33887DWBR2's wide 5 V VDD operating range and internal sleep mode for low quiescent-current standby. From 18-20 V cordless drills to 12 V handheld vacuum motors, the 5 A continuous rating handles both the running and stall-inrush conditions for motors up to ~100 W. The integrated load current feedback enables torque-limiting and stall detection without external sense resistors, which is crucial for cost-sensitive consumer designs. The exposed-pad 54-SOIC package fits standard 4-layer consumer PCB layouts.

Diferenciadores clave
- On-chip load current feedback eliminates external sense resistor (frente a Discrete MOSFET H-bridge (4x N-MOSFET + gate driver + 0.01 ohm shunt))
- 54-SOIC HSSOP exposed pad package is industry-standard footprint (frente a MC33931VW (44-SOIC exposed pad))

Notas de diseño
Estimated: at 5 A continuous load across the H-bridge and a typical 12 V supply, on-state power dissipation from RDS(ON) losses can exceed 2 W with 50% PWM duty cycle. The 54-SOIC exposed pad must be soldered to a PCB copper land of at least 1 square inch on a 4-layer board (2 oz outer copper) to keep junction temperature below thermal shutdown (typically 155 C). Without thermal landing, the part will enter foldback well before reaching 5 A continuous output, and motor torque will be unpredictable. For sustained 5 A drive in 24 V designs, evaluate a forced-air or chassis-mounted heatsink.
Place the VCP charge-pump capacitor (typically 100 nF ceramic X7R) as close to the VCP pin as possible, with short trace returns to the EP pad ground. Keep the high-current OUT1 and OUT2 traces wide (40+ mil) and short to minimize parasitic inductance that contributes to switching loss and back-EMF ringing. Decouple VDD with a 10 uF ceramic + 100 uF aluminum electrolytic bulk capacitor to absorb motor back-EMF energy during commutation events. Route IN1/IN2 and the FB output as short analog traces guarded from the OUT1/OUT2 power traces by a ground shield.
Do not operate the part above 28 V VDD - the internal MOSFETs and charge pump are not rated for 24 V industrial transients plus margin. Add a 30 V TVS diode at VDD for load-dump protection in automotive 12 V systems. Never leave SLP (sleep) floating - tie it to logic high through a 10 kohm resistor to guarantee a defined start state. Do not connect OUT1 and OUT2 together; doing so will cause a shoot-through short. Finally, de-rate the 5 A continuous figure to 3 A in sealed enclosures without airflow, even with a perfect thermal layout.
The FB (load current feedback) output is an analog signal that should be filtered with a 10 kohm + 100 nF RC low-pass to attenuate PWM switching noise before it reaches the MCU ADC. Without filtering, the ADC sample will be dominated by PWM edge transients and the closed-loop torque control will be unstable. Program the MCU ADC to sample the FB output in the middle of the PWM off-time to capture a clean current measurement. For applications requiring more bandwidth, increase PWM frequency above the audible band (>= 18 kHz) but below the 20 kHz part maximum.
