MC33887PEKR2 概述
An H-bridge motor driver is a type of power management IC that lets a microcontroller run a brushed DC motor in forward, reverse, and brake modes by steering current through two half-bridge legs; when integrated with current feedback, it sits in the broader motor-driver hierarchy above single half-bridge ICs and below system-on-module BLDC controllers. The feedback signal allows closed-loop torque or speed control without external shunt resistors, simplifying PCB layout and reducing BOM cost.
Key specifications include 5.0 A continuous / 8.0 A peak output current, 5 V to 28 V operating voltage (VLOAD), integrated current-sense output for the analog-to-digital converter on the host MCU, and an active-low sleep input with sub-50 uA quiescent current. Logic inputs (IN1, IN1, EN, FS, SLEEP) accept 3.3 V or 5 V CMOS signals, allowing direct interface to most automotive-grade microcontrollers without level shifters. The exposed thermal pad on the SOICW-EP 54 package provides a low thermal resistance path to the PCB copper, supporting continuous 5 A output with adequate board copper area.
The MC33887PEKR2 uses DMOS power transistors with a built-in charge pump to generate gate drive, achieving low Rds(on) per FET and minimizing conduction losses. Built-in protection includes over-current shutdown, under-voltage lockout, thermal shutdown, and cross-current (shoot-through) prevention via integrated dead-time control. The current-sense output scales load current through an internal sense FET, eliminating the need for an external shunt and giving a ratiometric analog feedback signal proportional to motor current.
Typical applications include automotive HVAC flap actuators, seat-position motors, window lift motors, mirror adjusters, robotic DC motor control, and industrial automation actuators up to 5 A continuous. The wide 5 V to 28 V supply range also supports 12 V and 24 V industrial battery or bus-powered systems. In the automotive body-electronics domain it is commonly used where PWM speed control and direction reversal are both required.
Designers should plan PCB copper layout around the exposed pad as the primary heatsink, observing SOA (safe operating area) limits at high duty cycles and low airflow. The charge-pump external capacitor pin needs a low-ESR 1 nF to 100 nF capacitor placed within a few millimeters of the device to ensure reliable gate drive; an inadequate capacitor causes shoot-through and catastrophic failure. Sense-resistor and current-feedback filter values should be selected per the application note to avoid false over-current trips during PWM transitions.

典型应用
MC33887PEKR2 适用于 7 应用s: Automotive HVAC Flap Actuators, Power Window Lift Motor Control, Electric Mirror and Seat Adjustment, Industrial 24 V Brushed DC Servo Loops, Robotics and Small Actuator Drives, 12 V / 24 V Cooling Fan Speed Control, Portable / Battery-Powered DC Pumps.
Automotive HVAC Flap Actuators
The MC33887PEKR2 is purpose-built for HVAC blend and mode door actuators in automotive body electronics, where 12 V brushed DC gear-motors need PWM speed control, bidirectional commutation, and closed-loop current monitoring. The IC's 5 V to 28 V supply range directly handles 12 V automotive rails (including load-dump transients when paired with external TVS clamps), and the integrated analog current-sense output lets the body control module detect end-stop stall without an external shunt resistor. AEC-Q100 qualification and operating temperature to +125C cover underhood and behind-dash thermal environments, while sub-50 uA sleep quiescent current preserves quiescent battery drain during vehicle storage. A typical application circuit uses 10 kHz PWM for stall-free actuator movement and a 100 nF charge-pump capacitor placed within 5 mm of the CP pin to maintain gate-drive integrity over the full -40C cold-crank envelope.
推荐
Power Window Lift Motor Control
Window-lift drives need 5 A to 8 A peak current for the anti-pinch reverse-pulse cycle, exactly within the MC33887PEKR2's 8 A peak window. The current-sense output enables the door control module to sense motor stall when the window reaches the door frame, triggering the anti-pinch reversal mandated by FMVSS 118. Because automotive door modules are sealed and operate at ambient temperatures up to +85C, the exposed-pad SOICW-EP package must be soldered to a continuous copper pour of at least 1 square inch on inner or outer PCB layers. Sleep mode at less than 50 uA helps meet the typical 80 uA quiescent-current budget for the entire door module in parked-vehicle state. A 5 V TVS diode on VLOAD protects against ISO 7637-2 inductive-load transients, while internal thermal shutdown handles mechanical jam fault scenarios up to +125C junction.
推荐
Electric Mirror and Seat Adjustment
Seat-position and mirror-adjustment motors in automotive cabins typically draw 2 A to 4 A continuous but can spike to 6 A at the gear-train stall. The MC33887PEKR2's 5 A continuous / 8 A peak envelope comfortably drives these loads with margin for cold-oil viscosity and stall conditions. Logic input compatibility with both 3.3 V and 5 V microcontrollers means the same IC works with virtually any automotive body-control MCU without external level shifters, simplifying multi-seat wiring-harness BOMs. The PWM-controlled current-sense output also enables soft-start profiles to avoid inrush tripping of module fuses; a 5 kHz to 20 kHz PWM frequency stays above the audible range to keep seat movements silent. The device's -40C to +125C operating range and AEC-Q100 grade make it suitable for cabin modules that must operate reliably from winter cold-soak to summer sun-loaded conditions.
推荐
Industrial 24 V Brushed DC Servo Loops
Industrial conveyor diverters, valve actuators, and small servo loads in factory automation often run on 24 V brushed DC motors with closed-loop current sensing - precisely the use-case the MC33887PEKR2 was designed to address. The 5 V to 28 V supply range covers 24 V industrial bus rails directly while still tolerating 24 V +/- 10% variation; the 8 A peak envelope handles stall-torque events for diverters and dampers. The analog current-sense output lets a PLC or industrial MCU run torque-limiting control loops without expensive external Hall-effect sensors or shunt resistors. Designers should add external flyback diodes or TVS clamps if driving highly inductive loads, because the MC33887 internally clamps back-EMF to VLOAD but extreme inductance can force the pin above 28 V. The exposed thermal pad requires a generous inner-layer copper pour and, in sealed enclosures, possibly a small heatsink or topside copper area to dissipate the 5 A x voltage-drop losses.
推荐
Robotics and Small Actuator Drives
Compact hobby and educational robotics arms, pan-tilt camera mounts, and gripper drives use 12 V brushed DC gear-motors in the 1 A to 5 A range where the MC33887PEKR2's monolithic H-bridge simplifies the drive electronics. By integrating the charge pump, gate drive, and current sense, the MC33887 lets a robot's central MCU directly control motor direction and read current feedback via a single analog pin, freeing the engineer from discrete half-bridge design. Battery-powered robots benefit from the sub-50 uA sleep current when motors are idle, and the 5 V to 28 V supply range works with 2S to 6S Li-ion packs (7.4 V to 25.2 V). Designers should still add a 100 nF charge-pump bypass capacitor right at the CP pin and keep PWM frequencies in the 20 kHz to 40 kHz range for inaudible operation during telepresence or video recording sessions.
推荐
12 V / 24 V Cooling Fan Speed Control
Cooling fans for telecom equipment, industrial inverters, and battery-backed server racks benefit from the MC33887PEKR2's PWM speed-control capability and current-sense feedback in a single SOICW-EP IC. At 12 V and 24 V fan bus rails (which fit the 5 V to 28 V envelope), the part drives a brushed DC fan motor in forward / reverse / brake modes, with tacho-style fault feedback derived by reading the FB pin's averaged current ripple. A typical closed-loop design uses the MCU to PWM the MC33887 at 25 kHz (above audible noise), with feedback smoothing through a simple RC low-pass filter on the analog current-sense output. The internal over-current and thermal shutdown features protect against locked-rotor conditions without external fuses, and the SOICW-EP's exposed pad dissipates the several-watt continuous losses on a 1 square-inch copper pour placed near the fan connector.
推荐
Portable / Battery-Powered DC Pumps
Battery-powered dosing pumps, portable medical infusion pumps, and compact fluid-control modules need a small 12 V brushed DC pump driver with closed-loop current sensing to detect line blockage - exactly the MC33887PEKR2 use-case. The IC's 5 V to 28 V envelope covers 4S Li-ion packs and 12 V lead-acid battery rails, while the sub-50 uA sleep quiescent current preserves battery life during long product storage periods in hospital or home-care settings. The integrated current-sense output feeds an ADC on the MCU so the firmware can detect motor stall (line blockage, dry-run, end of stroke) and alert the user before mechanical damage occurs. Designers should add 100 nF ceramic bypass at VLOAD and short, low-loop-area PCB routing to the motor output to keep PWM edge noise below EMI limits per IEC 60601-1-2 for medical devices.

关键差异点
- Integrated current-sense eliminates external shunt resistor （对比 Discrete H-bridge + external shunt designs)
- AEC-Q100 automotive qualified in 54-SOICW-EP （对比 TI DRV8871 (HTSSOP-28, industrial grade only))
- 5 V to 28 V wide supply covers 12 V and 24 V rails in one part （对比 ON Semi AMT49700 (6 V to 36 V in SOIC-26))
设计说明
The 54-SOICW-EP package dissipates the MC33887PEKR2's Rds(on) losses through the exposed thermal pad; for 5 A continuous operation the pad must be soldered to a copper pour of at least 1 square inch (approx. 25 mm x 25 mm) on the top layer or an inner power plane with thermal vias. At 25 C ambient the IC can deliver 5 A continuous with adequate copper, but inside sealed automotive enclosures at 85 C the practical continuous current drops to 3-4 A without forced airflow; derate by roughly 0.06 A per degree rise above 25 C, multiplying Rds(on) by the temperature coefficient (~1.4x at 125 C).
Place the charge-pump bypass capacitor (typically 100 nF X7R) within 5 mm of the CP pin and the VLOAD bulk capacitor within 10 mm of the VLOAD pins; keep the motor-output traces short and as far from the FB analog return as possible to avoid PWM-edge coupling into the current-sense signal. The exposed pad must be electrically tied to the power GND pins and the PCB thermal copper must extend on multiple layers stitched with 0.3 mm thermal vias at 1.2 mm pitch. For designs targeting 8 A peak, double-sided copper and a small SMT heatsink on top of the package are recommended; PCB land pattern follows the JEDEC MO-188 outline referenced in the manufacturer datasheet.
Do NOT drive brushless DC (BLDC) motors with the MC33887 - it is a brushed H-bridge, not a three-phase driver. Operating below 5 V supply risks charge-pump starvation and shoot-through across the half-bridge legs; always observe the 5 V minimum and add a 10 uF bulk + 100 nF ceramic bypass on VLOAD. Do not float the SLEEP pin (tie to VDD if unused) - a floating SLEEP input can intermittently enable the part during board bring-up. Avoid back-driving the motor during disable transitions because the integrated flyback clamp shares VLOAD with the supply rail and can briefly push VLOAD above 28 V on highly inductive loads - add a TVS for ISO 7637-2 compliance in automotive modules.
