MCZ33887EK Overview
What is an H-Bridge motor driver? An H-Bridge is a circuit configuration of four switching elements arranged in an 'H' topology that allows bidirectional current flow through a DC motor or other load. By selectively enabling diagonal pairs of switches, the direction of rotation can be reversed without mechanical relays. Integrated H-Bridge ICs combine the four power MOSFETs, gate drivers, charge pump, and protection logic in a single package, replacing discrete implementations that would otherwise require dozens of components.
Key features of the MCZ33887EK include a current feedback (load current sense) output that mirrors the motor current to an external ADC or comparator for precise closed-loop torque or speed control, integrated PWM capability with shoot-through protection, low-side current recirculation mode for free-wheeling braking, and comprehensive fault diagnostics including overcurrent, overtemperature, and undervoltage lockout (UVLO). The exposed thermal pad of the 54-HSOP package provides a low 1.0 C/W junction-to-case thermal resistance, supporting continuous 5 A operation without an external heatsink.
The architecture uses four paralleled power MOSFETs (two high-side, two low-side) controlled by an internal charge-pump gate drive that tolerates supply transients up to 28 V. The MCZ33887EK is qualified to the AEC-Q100 automotive standard, making it suitable for under-hood applications such as throttle control, HVAC flaps, mirror adjusters, and headlamp levelers. Internal logic supports both Sign-Magnitude and Locked Anti-Phase PWM control schemes.
Typical applications include automotive throttle-by-wire, electronic parking brake, HVAC damper actuators, industrial DC servo drives, brushed DC gear motors, and bi-directional solenoid drivers. The wide supply range (5-28 V) accommodates both 12 V automotive and 24 V truck/industrial buses.
When designing with this device, place the load current sense resistor close to the FB pin and add an RC filter to attenuate switching transients. The exposed thermal pad must be soldered to a copper pour of at least 1 square inch for reliable continuous 5 A operation. Below approximately 7 V supply, the internal charge pump loses regulation margin, so check worst-case cold-crank conditions.

Typical Applications
MCZ33887EK is suitable for 6 applications: Automotive Electronic Throttle Body, HVAC Damper and Blend Door Actuator, Industrial 24V Brushed DC Servo Drive, Power Side Mirror Adjuster and Folding, Headlamp Leveling Actuator, Solenoid and Valve Driver Cluster.
Automotive Electronic Throttle Body
The MCZ33887EK's 5 A continuous bidirectional drive and integrated load current feedback make it ideal for electronic throttle body (ETB) actuation. In this role the H-Bridge drives a brushed DC motor that positions the throttle plate based on the accelerator pedal input. The chip's AEC-Q100 qualification and -40 to +150 C junction rating cover under-hood conditions, while the load current feedback allows the engine ECU to close the loop on throttle plate position via torque or speed control. The 5-28 V supply range tolerates cold-crank transients and load-dump events when external TVS protection is added. Compared to discrete MOSFET H-Bridge designs, the integrated charge pump and shoot-through protection cut PCB area by approximately 60 percent and reduce design-in time.
Recommended
HVAC Damper and Blend Door Actuator
For automotive HVAC damper and blend-door actuators, the MCZ33887EK provides the bidirectional drive and stall detection needed for accurate flap positioning. The load current sense output lets the HVAC controller detect when the motor reaches its end-stop (stall condition) by monitoring sudden current spikes, removing the need for mechanical end-stop switches. Wide operating temperature range and AEC-Q100 qualification let the part live inside the dashboard plenum chamber. With the 54-HSOP exposed-pad package's 1.0 C/W junction-to-case thermal resistance, no external heatsink is required - the copper pour on the actuator PCB handles dissipation.
Recommended
Industrial 24V Brushed DC Servo Drive
The MCZ33887EK's 5-28 V supply margin pairs naturally with industrial 24 V brushed DC servo motors used in conveyor positioners, valve actuators, and small-format robotics. The 120 mOhm RDS(on) keeps dissipation down at full load - about 3 W at 5 A continuous - while the exposed-pad package rejects that heat through the PCB copper. Locked Anti-Phase PWM yields bidirectional speed control from a single sign-magnitude PWM input, simplifying the host MCU firmware. The 54-HSOP form factor also keeps motor drive circuitry compact for integration inside actuator housings.
Recommended
Power Side Mirror Adjuster and Folding
In automotive side-mirror adjust and fold mechanisms, two MCZ33887EK H-Bridges drive the horizontal, vertical, and fold motors. The integrated current-feedback path provides the body control module with stalled-motor detection, raising an error flag if a mirror stalls against ice or debris rather than burning out the motor windings. AEC-Q100 and -40 to +150 C junction tolerance ensure reliability in the door module environment. The exposed-pad package handles the thermal load without forced air or external heatsinks inside the mirror base.
Recommended
Headlamp Leveling Actuator
Front and rear headlamp leveling motors use the MCZ33887EK to dynamically trim beam aim as the vehicle loads change. The integrated analog current feedback enables the lighting ECU to drive the H-Bridge in PWM with closed-loop position control, while the overcurrent and overtemperature protection paths prevent headlamp misalignment under stalled-motor conditions. The chip's 5-28 V supply tolerates load-dump spikes common in automotive power networks, and the 54-HSOP exposed-pad package manages continuous 1-2 A motor current without a heatsink.
Recommended
Solenoid and Valve Driver Cluster
Latching and proportional solenoids in transmission shift, exhaust gas recirculation (EGR), and emissions systems need bidirectional current control with a sense path. The MCZ33887EK's load current feedback output directly drives an ADC for proportional solenoid control, while the H-Bridge topology allows both pull-in and hold current to be managed with the same hardware. AEC-Q100 and full -40 to +150 C rating allow under-hood mounting, and the 120 mOhm RDS(on) keeps dissipation low even on long-duration holds.

- Tighter internal current limit for safety-critical positioning (vs MCZ33887CFEK)
Design Notes
The 54-HSOP exposed-pad package provides a 1.0 C/W junction-to-case thermal resistance, but thermal performance depends entirely on the PCB copper area beneath the pad. Estimated: assuming a 1 square inch 2 oz copper pour on a 1.6 mm FR4 PCB, theta_JA is roughly 25 C/W. At 5 A continuous and 120 mOhm RDS(on), power dissipation is 3 W; the junction-to-ambient rise is approximately 75 C, leaving a -25 C-rated thermal margin versus the 150 C maximum junction rating. For sustained 5 A in sealed enclosures, add a top-side heatsink or forced airflow to keep the junction below 125 C.
Place the VS decoupling capacitors (typically 1 uF X7R ceramic + 100 uF electrolytic) as close as possible to the VS pins of the MCZ33887EK to handle the current recirculation paths during PWM. The exposed pad should be soldered to a copper pour of at least 1 square inch with 12+ thermal vias connecting to the bottom-side plane. Keep the FB trace short and surrounded by GND to minimize injection of switching noise into the analog current-sense signal.
Below approximately 7 V supply, the internal charge-pump starts losing regulation margin. Cold-crank voltages down to 4.5 V nominal can cause increased RDS(on) and thermal stress. Add a low-voltage cutoff in the firmware. Also beware of back-EMF from inductive loads - load-dump and inductive kickback can exceed the 28 V abs max unless external TVS diodes (e.g. SMBJ28A) are added across the motor leads. Never operate the MCZ33887EK with the exposed pad unsoldered; the junction will overheat quickly.
The analog load current feedback (FB) pin requires an external series resistor to convert the current to a voltage, plus an RC filter to attenuate PWM switching transients at the FB output. Keep the FB trace width narrow and reference it to a low-noise ground to avoid coupling high-frequency switching noise. If the FB signal feeds an ADC, add a 100 ns Sallen-Key low-pass filter to remove PWM switching artifacts without delaying the response to motor stalls.
