Product details
Overview
MC33186VW2R2 from NXP Semiconductors (formerly Freescale) is a monolithic H-bridge 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. Rated for 5.0 A continuous DC load current at TC < 100 °C, 28 V max supply, and -40 °C to +125 °C ambient operation, it serves in automotive seat/mirror actuators and industrial valve positioning.
For engineers reviewing the MC33186VW2R2 datasheet, MC33186VW2R2 pinout, MC33186VW2R2 application, or MC33186VW2R2 equivalent, key selection criteria include its 150 mΩ RDS(ON) per output at 25 °C, integrated overtemperature/overcurrent/undervoltage protection, diagnostic flag (SF), dual disable inputs (DI1/DI2), and compatibility with PWM up to 10 kHz.
Technical Context
The MC33186VW2R2 implements a fully integrated H-bridge with independent high-side and low-side MOSFETs, each featuring freewheeling diodes and current-limiting circuitry. Its internal charge pump enables full enhancement of high-side N-channel MOSFETs from a single 5–28 V supply, eliminating need for external bootstrap components.
Protection architecture includes three-tier fault response: undervoltage shutdown (4.15–4.65 V hysteresis), thermal shutdown (>160 °C junction), and dual overcurrent detection-high-side trip at 11 A typical, low-side current limiting at 6.5 A ±20% with 20.5 µs switch-off time. Fault status is reported via open-drain SF pin with <100 ms response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A at TC < 100 °C - supports sustained motor torque without external heatsink under defined thermal conditions |
| RDS(ON) per Output | 150 mΩ at 25 °C - minimizes conduction loss and self-heating during high-current operation |
| Supply Voltage Range | 5.0 V to 28 V (static), up to 40 V with derating - compatible with 12 V/24 V automotive and industrial rails |
| PWM Frequency Support | Up to 10 kHz - enables precise speed control while maintaining low audible noise and switching loss |
| Logic Input Compatibility | TTL/CMOS - interfaces directly with microcontrollers without level-shifting circuitry |
| Thermal Shutdown Threshold | 160 °C with 20 °C hysteresis - prevents permanent damage during overload or poor PCB thermal design |
| Diagnostic Flag (SF) | Open-drain, active-low - provides real-time fault indication for system-level error handling and recovery sequencing |
Pinout & Package
The MC33186VW2R2 is housed in a 20-pin HSOP (Heat Sink Overmolded Package) with exposed thermal pad (98ASH70702A), optimized for surface-mount assembly and enhanced heat dissipation via direct PCB copper connection to the metal slug (Pins 9,10,11,12).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AGND | Analog ground reference for internal logic and sensing circuits; must be short-traced to PGND on PCB |
| 2 | SF | Status flag output - open-drain, active-low signal indicating fault (overtemp, overcurrent, undervoltage) |
| 3,13 | IN2, DI1 | Direction input 2 and disable input 1 - TTL/CMOS-compatible with hysteresis for noise immunity |
| 4,5,16 | VBAT | Main power supply pins - internally connected; require minimum 47 µF bulk capacitance to suppress switching transients |
| 6,7,14,15 | OUT1, OUT2 | H-bridge outputs - integrated freewheeling diodes enable safe inductive load recirculation |
| 8 | COD | Coding input - selects functional mode: GND/NC enables DI1/DI2 as fault reset triggers; VCC disables DI1/DI2 |
| 17 | CP | Charge pump output - optional 33 nF decoupling capacitor improves PWM timing stability and maximum frequency |
| 9,10,11,12 | PGND / Metal Slug | Power ground and thermal interface - all grounds tied together; metal slug soldered to PCB for thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated SMARTMOS H-Bridge | Monolithic construction eliminates discrete MOSFETs, gate drivers, and external charge pump components |
| Dual Independent Disable Inputs | DI1 and DI2 allow hardware-level emergency shutdown or fault reset independent of main control signals |
| Programmable Coding Input (COD) | Selects between two functional configurations: standard fault reset via DI1/DI2 or alternate reset via IN1/IN2 |
| Stable Operation with Minimal BOM | Requires only one 47 µF VBAT capacitor and optional 33 nF CP capacitor - reduces bill-of-materials and layout complexity |
| Robust Protection Suite | Simultaneous monitoring of supply voltage, junction temperature, and both high-side/low-side currents ensures fail-safe operation in harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN840 | Lower continuous current (3.5 A), integrated current sense, no charge pump - requires external 5 V bias for high-side drive | Better suited for compact, cost-sensitive consumer devices; lacks 40 V transient rating and dual-disable architecture | Choose STSPIN840 when board space and integrated current sensing outweigh need for 5 A capability and automotive-grade transient robustness |
| DRV8876PWPR | Higher RDS(ON) (220 mΩ), integrated current regulation loop, no dedicated SF pin - uses SPI register readback for fault status | Preferred for closed-loop current-controlled systems; less suitable for simple hardware-fault signaling in safety-critical designs | Choose DRV8876PWPR when programmable current regulation and SPI diagnostics are required over deterministic open-drain fault flag behavior |
Compared with STSPIN840 and DRV8876PWPR, the MC33186VW2R2 delivers higher continuous current (5.0 A), lower conduction loss (150 mΩ), native 40 V transient tolerance, and hardware-based fault signaling via SF - making it optimal for automotive and industrial applications demanding robustness, simplicity, and deterministic failure response.

FAQ
What is the maximum continuous current rating for the MC33186VW2R2?
The MC33186VW2R2 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 metal slug soldered to a sufficient copper area. At higher temperatures or with reduced copper, derating applies per the thermal resistance data (RθJC = 2.0 °C/W).
Does the MC33186VW2R2 require an external charge pump capacitor?
The MC33186VW2R2 does not require an external capacitor on the CP pin to operate, but connecting up to 33 nF between Pin 17 (CP) and ground improves noise immunity, timing stability, and maximum achievable PWM frequency (up to 20 kHz during current limiting). Without it, performance remains functional but may exhibit increased jitter at high frequencies.
How does the diagnostic flag (SF) behave during fault conditions?
The SF pin on the MC33186VW2R2 is an open-drain output that pulls low within <100 ms upon detection of overtemperature, overcurrent, or undervoltage. It remains latched low until a valid reset event occurs - either a level change on DI1/DI2 (if COD = GND/NC) or on IN1/IN2 (if COD = VCC). The flag resets high only after fault clearance and successful reset sequence.
Can the MC33186VW2R2 drive inductive loads at 24 V nominal supply?
Yes, the MC33186VW2R2 is fully specified for 5.0 V to 28 V operation and can safely handle 24 V nominal supplies. Its dynamic destruction proof rating extends to 40 V for transients <500 ms, making it suitable for 24 V industrial and commercial systems with load-dump or inductive kickback events.
What is the purpose of the COD pin on the MC33186VW2R2?
The COD (Coding) pin on the MC33186VW2R2 configures the fault reset mechanism: when grounded or left floating, DI1 and DI2 serve as hardware reset triggers; when pulled to VCC, DI1/DI2 are disabled and IN1/IN2 assume reset functionality. This allows flexible integration into different control architectures without modifying firmware or external logic.
