Product details
Overview
MC33186VW1R2 from NXP Semiconductors (formerly Freescale) is a monolithic H-bridge motor driver IC designed for bidirectional control of fractional-horsepower DC motors and solenoids. It integrates SMARTMOS technology, internal charge pump, gate drive, logic control, and low-RDS(ON) MOSFETs, delivering continuous 5.0 A DC load current at TC < 100 °C with 150 mΩ typical RDS(ON) per output at 25 °C. It operates from 5.0–28 V VBAT, supports PWM up to 10 kHz, and features integrated freewheeling diodes - used in automotive seat/mirror actuators and industrial valve drivers.
For engineers reviewing the MC33186VW1R2 datasheet, MC33186VW1R2 pinout, MC33186VW1R2 application, or MC33186VW1R2 equivalent, key selection criteria include its 20-pin HSOP-EP package with exposed thermal pad, dual disable inputs (DI1/DI2), diagnostic open-drain status flag (SF), coding input (COD), and robust protection suite including overtemperature, short-circuit, and undervoltage shutdown.
Technical Context
The MC33186VW1R2 implements a fully integrated half-bridge pair with independent high-side and low-side MOSFETs per channel, controlled via TTL/CMOS-compatible logic inputs (IN1/IN2) and two disable inputs (DI1/DI2). Its internal charge pump enables full enhancement of high-side N-channel MOSFETs without external bootstrap components, supporting operation down to 5.0 V VBAT.
Protection architecture includes real-time current limiting (6.5 A ±20% on low sides), fast overcurrent detection (≥8.0 A triggers tristate within 4–8 μs), thermal shutdown at 160–190 °C with hysteresis, and undervoltage lockout (4.15–4.65 V switch-off range). Fault status is reported via open-drain SF pin, resettable via DI1/DI2 edge transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBAT Range | 5.0–28 V continuous; up to 40 V with derating - supports 12 V/24 V automotive and industrial rails. |
| Continuous Output Current | 5.0 A at TC < 100 °C - enables direct drive of medium-power DC motors without external heatsinking under moderate PCB copper area. |
| RDS(ON) (per FET) | 150 mΩ typ @ 25 °C - limits conduction loss to ~3.75 W per side at 5 A, critical for thermal management in HSOP-EP package. |
| PWM Frequency Support | Up to 10 kHz - sufficient for smooth torque control in brushed DC motor applications without audible noise. |
| Logic Input Compatibility | TTL/CMOS - interfaces directly with microcontrollers (e.g., S12, Kinetis, STM32) without level-shifting circuitry. |
| Status Flag (SF) | Open-drain, active-low fault indicator - provides immediate system-level fault visibility for safety-critical actuator control loops. |
| Thermal Shutdown Threshold | 160–190 °C with 20–30 °C hysteresis - prevents latch-up during transient overload while enabling automatic recovery after cooldown. |
Pinout & Package
The MC33186VW1R2 is housed in a 20-pin HSOP-EP (Heat Sink Overmolded Package – Exposed Pad) with 16.0 mm × 11.0 mm body and 12.3 mm × 7.1 mm exposed copper thermal pad. The package is Pb-free (RoHS-compliant) and optimized for surface-mount assembly with enhanced thermal dissipation via soldered exposed pad to PCB ground plane.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AGND | Analog ground reference - must be tied to power ground (PGND) with shortest possible PCB trace to minimize noise coupling into internal logic. |
| 2 | SF | Status flag (open-drain, active-low) - asserts low on overtemperature, overcurrent, or undervoltage; reset by DI1/DI2 edge transition. |
| 3,13 | IN2, DI1 | Logic input / disable input - IN2 controls OUT2 direction; DI1 disables both outputs when high (per truth table state 5). |
| 4,5,16 | VBAT | Main supply pins - internally connected; require parallel 47 μF minimum bulk capacitance to suppress switching transients and prevent latch-up. |
| 6,7,14,15 | OUT1, OUT2 | H-bridge outputs with integrated freewheeling diodes - drive motor terminals directly; metal slug (pins 9–12) connects to PGND for thermal and electrical return path. |
| 8 | COD | Coding input - selects DI1/DI2 or IN1/IN2 as reset trigger for stored faults; GND = DI1/DI2 active, VCC = IN1/IN2 active. |
| 17 | CP | Charge pump output - decoupled with ≤33 nF capacitor to GND; improves high-side gate drive stability and maximum PWM frequency. |
| 18,19 | DI2, IN1 | Disable input / logic input - DI2 disables both outputs when low (state 6); IN1 controls OUT1 direction in forward/reverse modes. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables full N-channel high-side drive without external bootstrap components, supporting 5.0 V minimum VBAT operation. |
| Dual independent disable inputs (DI1/DI2) | Allow hardware-level fail-safe shutdown independent of MCU control signals - critical for ASIL-B functional safety compliance. |
| Current limiting with blanking time | 6.5 A ±20% trip threshold with 12–21 μs blanking window prevents false triggering during PWM turn-on transients. |
| Diagnostic status flag (SF) | Single-pin fault reporting with sub-100 ms response - simplifies system-level diagnostics and reduces GPIO count on host controller. |
| Exposed thermal pad (HSOP-EP) | Reduces RθJC to 2.0 °C/W - enables >4 W power dissipation with minimal PCB copper area, improving reliability in space-constrained modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8876PWPR | Lower RDS(ON) (80 mΩ), integrated current sense, but requires external 5 V bias supply for charge pump. | Preferred where precise current monitoring is required; less suitable for 5 V-only systems due to auxiliary supply dependency. | Select DRV8876PWPR if closed-loop current control is needed and auxiliary 5 V rail is available. |
| STSPIN840HTR | Higher voltage rating (45 V), smaller QFN package, but lower continuous current (3.5 A) and no diagnostic flag output. | Better for compact, high-voltage industrial tools; lacks SF pin, requiring external fault detection circuitry. | Choose STSPIN840HTR for space-constrained 24–45 V applications where diagnostic simplicity is acceptable. |
Compared with DRV8876PWPR and STSPIN840HTR, the MC33186VW1R2 offers superior integration for 12/24 V automotive and industrial actuators - combining robust 5 A drive, built-in fault reporting via SF, and single-supply operation - without requiring auxiliary bias rails or external sense resistors.

FAQ
What is the maximum continuous output current supported by the MC33186VW1R2?
The MC33186VW1R2 supports 5.0 A continuous DC load current when case temperature (TC) remains below 100 °C. This rating assumes proper PCB thermal design with the exposed pad soldered to a sufficient copper area. At higher temperatures or with limited copper, derating applies - consult the thermal resistance data (RθJA = 29 °C/W on standard test board) to calculate junction temperature rise.
Does the MC33186VW1R2 require an external charge pump capacitor?
Yes, the MC33186VW1R2 requires an external capacitor (up to 33 nF) between CP (pin 17) and PGND to stabilize the internal charge pump. While the device can operate without it, omitting the capacitor degrades high-side gate drive performance, reduces maximum PWM frequency, and increases switching losses. A 22 nF X7R ceramic capacitor placed close to pin 17 is recommended for optimal 10 kHz operation.
How does the status flag (SF) pin function on the MC33186VW1R2?
The SF pin on the MC33186VW1R2 is an open-drain output that goes low during any fault condition - including overtemperature, overcurrent (>8.0 A), or undervoltage (<4.15 V). It remains latched low until cleared by an edge transition on DI1 or DI2 (or IN1/IN2 if COD = VCC). Response time is typically under 100 ms, enabling rapid system-level fault detection and safe shutdown sequencing in the MC33186VW1R2.
Can the MC33186VW1R2 operate from a 5 V supply?
Yes, the MC33186VW1R2 operates from 5.0 V to 28 V VBAT, with full functionality including charge pump operation and 5.0 A drive capability. However, at 5.0 V, output RDS(ON) increases slightly, and thermal margin decreases - ensure adequate PCB copper and airflow. The undervoltage lockout activates below ~4.15 V, preventing unreliable operation.
What is the purpose of the COD pin on the MC33186VW1R2?
The COD (coding) pin on the MC33186VW1R2 selects which input pair resets stored faults: when grounded, DI1/DI2 edges clear faults; when tied to VCC, IN1/IN2 edges perform reset. This flexibility allows designers to align fault-clearing behavior with system-level safety architecture - e.g., using dedicated hardware disable lines (DI1/DI2) for emergency stop, or motor command lines (IN1/IN2) for normal restart - without modifying firmware for the MC33186VW1R2.
