MC33886DHR2 Übersicht
An H-Bridge motor driver is a power IC that uses four switches arranged in an H configuration to drive a DC motor or inductive load bidirectionally from a single supply rail. By toggling diagonal switch pairs, current flows through the load in either direction, while PWM modulation of those switches regulates average voltage and thus motor speed. The H-bridge belongs to the wider family of motor driver ICs under the PMIC (Power Management Integrated Circuit) umbrella, alongside stepper drivers, brushless DC (BLDC) controllers, and solenoid drivers.
Key features include a wide 5 V to 40 V supply range, 5.0 A continuous output current, internal charge-pump gate drive, low RDS(ON) power MOSFET output stage, PWM capability up to 10 kHz and beyond, built-in thermal protection, and over-current shutdown. The 20-pin HSOP package exposes a thermal pad that enables direct PCB heat spreading, allowing the device to deliver rated current without an external heatsink in well-designed layouts.
The MC33886 uses a CMOS logic interface for input controls, with separate high-side and low-side recirculation modes that allow easy implementation of fast/slow decay current control loops. Its integrated charge pump generates the gate-drive voltage for the high-side N-channel MOSFETs from a single supply rail, eliminating the need for an external bootstrap circuit. Low RDS(ON) keeps conduction losses manageable even at 5 A.
Typical applications include automotive body electronics (window lifters, seat adjusters, mirror actuators, door locks), industrial fractional-horsepower DC motor control, bi-directional solenoid valves, relay replacement, and small DC fan pumps. The 40 V maximum supply also makes it suitable for 12 V and 24 V industrial battery systems.
When laying out the MC33886, dedicate substantial copper area to the exposed thermal pad on the top or bottom layer and stitch thermal vias directly under the pad to the opposite plane; inadequate thermal sinking is the dominant cause of MC33886 thermal-shutdown failure in field designs. Decouple the supply pin with a low-ESR ceramic capacitor placed within 5 mm of the IC.

MC33886 Sicherer Arbeitsbereich (estimated from datasheet derating curves)
Typische Anwendungen
MC33886DHR2 ist geeignet für 6 Anwendungs: Automotive Window Lifter Motor Drive, Seat Adjustment and Mirror Actuator Drive, Industrial 24V Solenoid and Valve Control, Relay Replacement for DC Loads, Fractional-Horsepower DC Motor Drive, Door Lock and Trunk Latch Actuator.
Automotive Window Lifter Motor Drive
The MC33886DHR2's 5.0 A continuous H-bridge and 5-40 V supply make it a strong fit for automotive window-lifter motor modules drawing from a 12 V battery. With 20 kHz PWM capability the device regulates motor speed smoothly, and its integrated charge pump eliminates external bootstrap components, shrinking the PCB. Built-in thermal shutdown with -40 C to +125 C operation survives under-hood temperatures during stalled-motor lock events.
Empfohlen
Seat Adjustment and Mirror Actuator Drive
Bi-directional seat adjusters and power mirrors need a small, robust H-bridge rated for continuous stall current - exactly what the MC33886DHR2 delivers at 5 A continuous. The 5-40 V range tolerates load-dump transients common in 12 V automotive networks, while the CMOS logic interface talks directly to a body-control MCU. Its HSOP-20 exposed pad allows the module to stay compact while dissipating up to several watts without an external heatsink.
Empfohlen
Industrial 24V Solenoid and Valve Control
The MC33886DHR2's 40 V upper supply limit and 5 A drive comfortably handle 24 V industrial solenoid valves, hydraulic proportional valves, and pneumatic actuators. The internal charge pump ensures full gate enhancement for low-loss switching at high current, and the PWM input allows precise proportional control of valve flow. Built-in short-circuit protection is critical when driving inductive loads that can produce large back-EMF on turn-off.
Empfohlen
Relay Replacement for DC Loads
Replacing mechanical relays with the MC33886DHR2 eliminates contact bounce, arcing, and mechanical wear in DC load switching. Its 5 A continuous rating covers lighting, fans, and small heaters, while the 5-40 V range matches both 12 V and 24 V systems. PWM capability extends the use case to dimming or variable-speed fan control where an electromechanical relay cannot operate.
Empfohlen
Fractional-Horsepower DC Motor Drive
Fractional-HP brushed DC motors in pumps, small fans, conveyor rollers, and vending-machine mechanisms are the canonical use case for the MC33886DHR2. With 5 A continuous capability the IC can drive motors up to roughly 100 W from a 24 V supply, while PWM speed control and built-in current limiting protect against stall conditions. The HSOP-20 footprint and exposed pad keep board area small enough for tightly packaged consumer and industrial equipment.
Empfohlen
Door Lock and Trunk Latch Actuator
Automotive door-lock and trunk-latch actuators draw brief inrush currents of several amps during engagement - well within the MC33886DHR2's 5 A continuous capability, and its integrated short-circuit protection contains latch faults. The 5-40 V supply range survives cold-cranking and load-dump events on 12 V automotive rails, while the small HSOP-20 footprint fits the actuator module's tight board. Bidirectional control is achieved with just two CMOS logic inputs.

Wichtigste Unterscheidungsmerkmale
- Integrated charge pump removes external bootstrap requirement (vs. MC33883HEGR2)
- Wide 5-40 V supply supports 12 V and 24 V systems from a single part (vs. MC33886 without DHR2 suffix)
- 5 A continuous monolithic H-bridge in HSOP-20 (vs. Discrete 4-MOSFET H-bridge designs)
Designhinweise
Estimated: At 5 A continuous and a 12 V supply, total dissipation in the H-bridge depends on RDS(ON). With RDS(ON) of approximately 100 mOhm per FET (datasheet typical, not extracted in the provided data), conduction loss at 5 A is roughly 2.5 W per side and ~5 W total at low-side recirculation. Keep the exposed thermal pad soldered to a copper pour of at least 1 square inch on the top side plus an array of thermal vias to the opposite plane - inadequate thermal connection is the dominant cause of thermal-shutdown in MC33886 designs.
Place a low-ESR ceramic bypass capacitor (typically 0.1 uF in parallel with 10 uF or higher) within 5 mm of the VPWR pins (1 and 3). The two VPWR pins must be bonded together on the PCB. The high di/dt currents from the H-bridge switching demand short, wide PCB traces on the output nodes; route motor outputs on one side of the package and logic signals on the opposite side to minimize noise coupling into IN1/IN2/EN logic lines.
Do not float any unused logic input - tie unused IN1/IN2/EN pins to defined logic levels (GND or VDD) to prevent partial turn-on and high shoot-through currents. Avoid operating above the 40 V absolute maximum, even on inductive transients - add a TVS or freewheeling clamp if the motor's back-EMF energy can exceed this on release. For PWM operation, choose slow-decay mode for higher current at low RPM and fast-decay mode for better control at low duty cycles.
PWM edge rates on the MC33886 H-bridge output can produce conducted EMI above 100 MHz. Add small RC snubbers (10-100 ohm + 1-10 nF) directly across each output to ground only if needed for EMI compliance; the snubber value should be tuned empirically to avoid excessive switching loss. Keep the PWM frequency in the 15-20 kHz range for most motor applications to stay above the audible band while limiting switching loss.
Compliance-Informationen
RoHS compliant per DigiKey listing (NXP). Manufacturer temperature grade -40 C to +125 C supports automotive environments, but AEC-Q100 explicit qualification letter was not present in the provided web data and must be verified from NXP's product page before ADAS or safety-critical use.
