Product details
Overview
MC33887VW from NXP Semiconductors is a monolithic 5.0 A automotive-grade H-bridge power IC with integrated load current feedback (1/375 ratio), active current limiting (5.2–7.8 A), and fault reporting (undervoltage, overtemperature, short-circuit). It operates from 5.0 V to 28 V supply, supports PWM up to 10 kHz, and delivers low RDS(on) of 120 mΩ typical - enabling closed-loop DC motor control in electronic throttle and EGR systems.
For engineers reviewing the MC33887VW datasheet, MC33887VW pinout, MC33887VW application, or MC33887VW equivalent, this page provides verified technical context, HSOP20 package mapping, real-world motor control use cases, and two validated alternative parts for automotive-grade H-bridge selection.
Technical Context
The MC33887VW implements an internal charge pump to drive high-side N-channel MOSFETs across its full 5.0–28 V operating range, eliminating external bootstrap circuitry. Its dual disable inputs (D1 active-high, D2 active-low) and enable (EN) pin support flexible sleep/standby sequencing with ≤50 µA quiescent current.
Current sensing is implemented via a proportional constant-current FB output referenced to AGND, delivering 1.33 µA per mA of high-side load current - directly compatible with microcontroller ADC inputs without scaling resistors. Fault status (FS) is open-drain active-low and reports undervoltage, thermal shutdown (175 °C trip, 10 °C hysteresis), and short-circuit events independently of input logic states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A - sustained DC load capability with junction temperature ≤150 °C under proper heatsinking |
| RDS(on) (Typical) | 120 mΩ - low conduction loss at 25 °C, enabling efficient motor drive at 12–24 V automotive rails |
| Current Feedback Ratio | 1/375 - FB pin delivers 1.33 µA per mA of high-side current, enabling direct ADC monitoring |
| Active Current Limit Threshold | 5.2–7.8 A - internal constant-OFF-time PWM regulation on low-side MOSFETs prevents destructive overcurrent |
| Supply Voltage Range | 5.0–28 V - fully specified operation; limited functionality up to 40 V with degraded charge pump performance |
| Fault Reporting | Open-drain FS pin - asserts low on undervoltage, overtemperature (175 °C), or short-circuit (ISCH ≥11 A / ISCL ≥8 A) |
| PWM Frequency Support | Up to 10 kHz - compatible with standard motor control loop bandwidths and audible noise mitigation |
| Thermal Rating | AEC-Q100 Grade 1 - qualified for −40 °C to +125 °C ambient operation in automotive powertrain applications |
Pinout & Package
MC33887VW is packaged in HSOP20 (SOT397-2): plastic heatsink small outline package, 20-pin, 1.27 mm pitch, 11 mm × 15.9 mm × 3.2 mm body, with exposed thermal pad DC-coupled to AGND and PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 20) | Enable control | Logic high enables full operation; logic low forces sleep mode (≤50 µA IQ) |
| IN1 (Pin 3), IN2 (Pin 19) | H-bridge polarity control | TTL/CMOS-compatible inputs; IN1 controls OUT1, IN2 controls OUT2 (H = high-side ON) |
| D1 (Pin 18), D2 (Pin 13) | Complementary disable | D1 high or D2 low forces both outputs to high-impedance 3-state; rest of circuit remains active |
| OUT1 (Pins 6–7), OUT2 (Pins 14–15) | H-bridge power outputs | Paired pins reduce trace inductance and current density; each pair connects to one motor terminal |
| FB (Pin 8) | Current feedback output | Ground-referenced constant-current source (IFB = IOUT(HS)/375); connects directly to MCU ADC |
| FS (Pin 2) | Fault status indicator | Open-drain output requiring external 5 V pull-up; low = undervoltage, overtemperature, or short-circuit |
| V+ (Pins 4–5, 16) | Positive supply | Three dedicated pins minimize IR drop; must be short-traced and low-impedance on PCB |
| PGND (Pins 9–12) | Power ground | Four parallel pins handle high return current; must be low-impedance connection to thermal pad |
| AGND (Pin 1) | Analog ground | Separate low-noise reference for FB and internal analog circuits; tied to PGND via low-Z path |
| CCP (Pin 17) | Charge pump capacitor | Connects external reservoir capacitor (typically 100 nF X7R) to sustain gate drive above V+ |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN840 | 4.5 A continuous, 3.0 A peak; integrated current sense amplifier (not proportional current source); no FS pin; SPI interface for diagnostics | Requires external ADC reference and signal conditioning; better suited for compact, digitally controlled stepper/motor combos than analog-closed-loop DC motors | Choose STSPIN840 when digital control, smaller footprint (QFN32), and SPI-configurable parameters outweigh need for analog current feedback simplicity |
| DRV8876N | 6.5 A continuous; 1/200 current sense ratio; integrated current sense amplifier with rail-to-rail output; no dedicated fault status pin | Lacks open-drain FS reporting; requires external comparator or MCU GPIO polling for fault detection; higher current rating but less automotive qualification depth | Choose DRV8876N when higher current headroom and integrated sense amp output simplify analog signal chain, and AEC-Q100 Grade 1 is not mandatory |

FAQ
What is the maximum continuous current rating of the MC33887VW?
The MC33887VW is rated for 5.0 A continuous DC load current, provided the junction temperature remains ≤150 °C. This assumes proper PCB heatsinking via the exposed thermal pad and adequate copper area on PGND/AGND planes. Peak current limiting activates between 5.2 A and 7.8 A to protect against transient overloads.
How does the current feedback (FB) pin of the MC33887VW interface with a microcontroller?
The FB pin of the MC33887VW delivers a ground-referenced constant-current output equal to 1/375 of the high-side load current (e.g., 1.33 µA per mA). It connects directly to a microcontroller's ADC input without external amplification or level-shifting - enabling precise, low-drift current monitoring for torque estimation or open-load detection in the MC33887VW.
Does the MC33887VW support PWM control, and what is its maximum frequency?
Yes, the MC33887VW supports external PWM control of its H-bridge outputs up to 10 kHz. This is achieved by holding one input (IN1 or IN2) high while applying the PWM signal to the other. The device's <18 µs output delay and 2–8 µs rise/fall times ensure clean switching at this frequency, making the MC33887VW suitable for responsive motor speed and torque control loops.
What fault conditions does the FS pin of the MC33887VW report?
The FS pin of the MC33887VW is an open-drain active-low output that reports three critical fault conditions: undervoltage (V+ < 4.15 V), overtemperature (junction ≥175 °C), and short-circuit (high-side ≥11 A or low-side ≥8 A). It requires a 5 V pull-up resistor and asserts low independently of input logic - ensuring reliable fault signaling in the MC33887VW even during controller reset or communication loss.
Is the MC33887VW AEC-Q100 qualified, and what grade does it meet?
Yes, the MC33887VW is fully AEC-Q100 qualified to Grade 1, meaning it is certified for operation across the −40 °C to +125 °C ambient temperature range with rigorous stress testing for automotive powertrain and chassis applications. This qualification covers the entire HSOP20 package variant, including the MC33887VW, and validates its reliability under vibration, thermal cycling, and humidity exposure.
