Product details
Overview
MC33186HVW2R2 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 charge-pump gate drive, logic control, and low-RDS(ON) MOSFET outputs, delivering 5.0 A continuous DC load current at TC < 100 °C, with PWM capability up to 10 kHz, and operates across 5.0–28 V supply range in automotive and industrial motion systems.
For engineers reviewing the MC33186HVW2R2 datasheet, MC33186HVW2R2 pinout, MC33186HVW2R2 application, or MC33186HVW2R2 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 HSOP-20 exposed-pad thermal package.
Technical Context
The MC33186HVW2R2 implements a SMARTMOS-based H-bridge architecture with independent high-side and low-side MOSFETs, each featuring integrated freewheeling diodes and current-limiting circuitry. Its internal charge pump enables full enhancement of high-side N-channel MOSFETs without external bootstrap components.
Control logic supports four operational modes-forward, reverse, high-side freewheeling, and low-side freewheeling-as defined by IN1/IN2 states under active DI1/DI2 enable conditions. Fault management includes latched status flag (SF) output, resettable via input edge transitions on DI1/DI2 or IN1/IN2 depending on COD pin configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A at case temperature < 100 °C - defines maximum sustained motor drive capability without forced cooling |
| RDS(ON) per Channel | 150 mΩ typical at 25 °C - determines conduction loss and thermal rise under load |
| Supply Voltage Range | 5.0 V to 28 V (static), up to 40 V with derating - supports 12 V/24 V automotive and industrial battery rails |
| PWM Frequency Max | 10 kHz - sets upper limit for speed/torque modulation resolution in closed-loop motor control |
| Logic Input Compatibility | TTL/CMOS - ensures direct interfacing with microcontrollers and DSPs without level-shifting |
| Thermal Shutdown Threshold | 160 °C to 190 °C with 20–30 °C hysteresis - prevents permanent junction damage during overload or poor heatsinking |
| Status Flag (SF) | Open-drain, active-low fault indicator with < 100 ms response - enables real-time system-level fault detection and recovery sequencing |
Pinout & Package
The MC33186HVW2R2 is housed in a 20-pin HSOP (Heat Sink Over Molded Plastic) package with exposed thermal pad (98ASH70702A), optimized for surface-mount assembly and high-power dissipation. The copper base plate provides low thermal resistance (RθJC = 2.0 °C/W) and requires PCB copper area for effective heat transfer.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AGND | Analog ground reference for internal logic and sensing - must be short-traced and star-connected to PGND |
| 2 | SF | Open-drain status flag output - pulled low during overtemperature, overcurrent, or undervoltage faults |
| 3,13 | IN2, DI1 | Direction and disable control inputs with hysteresis - TTL/CMOS compatible; DI1 disables both outputs when high |
| 4,5,16 | VBAT | Main power supply pins - internally split to feed left/right high-sides and analog core; require ≥47 μF bulk capacitance |
| 6,7,14,15 | OUT1, OUT2 | H-bridge output terminals - each integrates freewheeling diode and supports bidirectional current flow |
| 8 | COD | Coding input - selects whether DI1/DI2 or IN1/IN2 trigger fault reset (GND = DI1/DI2 active; VCC = IN1/IN2 active) |
| 9,10,11,12 | PGND | Power ground terminals - connected to metal slug; must be low-inductance, wide-copper PCB connection to thermal pad |
| 17 | CP | Charge pump output - decoupled with ≤33 nF capacitor to stabilize gate drive voltage for high-side MOSFETs |
| 18,19 | DI2, IN1 | Second disable and direction input - DI2 disables outputs when low; IN1 controls forward/reverse state with IN2 |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Charge Pump | Enables full gate drive for high-side N-MOSFETs without external bootstrap circuitry or timing constraints |
| Current Limitation | 6.5 A ±20% with 20.5 μs switch-off time - protects against transient overloads while maintaining controllability |
| Dual Disable Inputs | DI1 (active-high) and DI2 (active-low) allow flexible system-level shutdown coordination and safety interlocks |
| Diagnostic Status Flag | Single open-drain SF pin reports all critical faults (overtemp, overcurrent, undervoltage) with latch-and-reset behavior |
| Robust Protection Suite | Includes overtemperature shutdown, short-circuit detection (≥8.0 A), and 40 V transient tolerance on VBAT |

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 |
|---|---|---|---|
| DRV8876PWPR | Lower RDS(ON) (80 mΩ), integrated current sense, but no diagnostic flag output | Requires external fault monitoring circuitry; better suited for cost-sensitive consumer-grade actuators | Choose DRV8876PWPR when current sensing is prioritized over integrated fault reporting |
| VNH7040ASTR | Higher voltage rating (41 V), SPI interface, but larger SO-24 package and no charge pump | Supports advanced diagnostics via SPI, but needs external high-side gate drivers for 24 V+ operation | Choose VNH7040ASTR when digital configurability and extended voltage headroom outweigh board space constraints |
Compared with DRV8876PWPR and VNH7040ASTR, the MC33186HVW2R2 offers balanced integration of protection, diagnostics, and thermal performance in a compact HSOP package - making it optimal for automotive and industrial applications where reliability, fault visibility, and ease of layout are critical.

FAQ
What is the maximum continuous current rating for the MC33186HVW2R2?
The MC33186HVW2R2 supports 5.0 A continuous DC load current when case temperature remains below 100 °C. This rating assumes proper PCB thermal design with the exposed pad soldered to sufficient copper area. At higher temperatures or with limited heatsinking, current must be derated per the device's thermal characteristics and RθJA values specified in the datasheet. The MC33186HVW2R2 also features current limiting at 6.5 A ±20% to protect against transient overloads.
Does the MC33186HVW2R2 require an external charge pump capacitor?
Yes, the MC33186HVW2R2 requires an external capacitor (up to 33 nF) between CP (Pin 17) and ground to stabilize the internal charge pump voltage. While the device can operate without this capacitor, omitting it degrades switching speed, increases propagation delay, and reduces maximum usable PWM frequency. The MC33186HVW2R2 datasheet specifies that including the CP capacitor enables full 20 kHz switching capability and improves noise immunity during high-frequency operation.
How does the status flag (SF) pin function on the MC33186HVW2R2?
The SF pin on the MC33186HVW2R2 is an open-drain, active-low diagnostic output that asserts low during overtemperature, overcurrent, or undervoltage events. It remains latched until reset by a valid edge transition on either DI1/DI2 or IN1/IN2, depending on the COD pin configuration. The MC33186HVW2R2 responds within 100 ms of fault onset, providing deterministic fault signaling for system-level safety monitoring and recovery sequencing without requiring polling or additional hardware.
Can the MC33186HVW2R2 operate from a 40 V supply?
The MC33186HVW2R2 supports dynamic operation up to 40 V for durations less than 500 ms, but its static absolute maximum VBAT rating is 28 V. Operation above 28 V requires strict derating of electrical specifications-including reduced current capability, increased thermal stress, and potential reduction in lifetime reliability. The MC33186HVW2R2 datasheet explicitly warns that exceeding 28 V continuously may compromise protection thresholds and thermal stability, so 40 V use is restricted to transient suppression scenarios only.
What is the purpose of the COD pin on the MC33186HVW2R2?
The COD (Coding) pin on the MC33186HVW2R2 selects the input pair used to reset latched faults: when grounded or left floating, DI1 and DI2 control reset; when tied to VCC, IN1 and IN2 assume reset responsibility. This flexibility allows system designers to align fault-clearing behavior with existing control architecture-e.g., using dedicated safety disable lines (DI1/DI2) in automotive modules or repurposing motor direction inputs (IN1/IN2) in simpler industrial controllers. The MC33186HVW2R2 truth table defines exact state transitions for both configurations.
