Product details
Overview
MC33186HVW2 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. It delivers continuous 5.0 A load current at TC < 100 °C, supports PWM up to 10 kHz, and operates from 5.0 V to 28 V supply with transient tolerance to 40 V - used in automotive seat/mirror actuators and industrial valve drivers.
For engineers reviewing the MC33186HVW2 datasheet, MC33186HVW2 pinout, MC33186HVW2 application, or MC33186HVW2 equivalent, this page provides verified functional identity, thermal derating guidance, truth-table–driven fault recovery behavior, diagnostic flag timing (<100 ms), and HSOP-EP package thermal resistance (RθJC = 2.0 °C/W) critical for motor-control PCB layout and safety-critical system validation.
Technical Context
The MC33186HVW2 implements dual high-side/low-side MOSFET output stages with integrated freewheeling diodes and independent overcurrent detection on both sides. Its charge-pump circuit enables full enhancement of high-side N-channel MOSFETs without external bootstrap components, supporting operation down to 5.0 V VBAT.
Protection architecture includes undervoltage lockout (4.15–4.65 V hysteresis), overtemperature shutdown (160–190 °C trip), short-circuit detection (>8.0 A), and current limiting (6.5 A ±20%) with blanking time (12–21 μs) and switch-off delay (15–26 μs) - all coordinated via open-drain status flag (SF) with fault storage and input-triggered reset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A at case temperature <100 °C - defines maximum sustained motor torque without forced cooling |
| RDS(ON) per Channel | 150 mΩ 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 systems with load-dump margin |
| PWM Frequency Support | Up to 10 kHz - enables fine-speed resolution while maintaining MOSFET switching efficiency |
| Status Flag Response | <100 ms fault assertion - meets ISO 26262 ASIL-B diagnostic timing requirements for actuator monitoring |
| Logic Input Compatibility | TTL/CMOS - allows direct interface with microcontrollers without level-shifting circuitry |
| Thermal Resistance RθJC | 2.0 °C/W - enables accurate junction temperature estimation using measured case temperature |
Pinout & Package
The MC33186HVW2 is housed in a 20-pin HSOP package with exposed thermal pad (98ASH70702A), optimized for surface-mount assembly and high-power dissipation. The copper base plate is soldered directly to PCB copper pour for low-impedance heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AGND | Analog ground reference - must be tied to PGND with minimal trace length to avoid noise coupling into logic circuits |
| 2 | SF | Open-drain status flag - active-low indicates fault (overtemp, overcurrent, undervoltage); requires external pull-up |
| 3,13 | IN2, DI1 | Input/control pins with hysteresis - IN2 controls OUT2 direction; DI1 disables outputs when high |
| 4,5,16 | VBAT | Main power supply inputs - Pins 4/5 feed left high-side/analog logic; Pin 16 feeds right high-side/charge pump; all must be paralleled with ≥47 μF capacitor |
| 6,7,14,15 | OUT1, OUT2 | H-bridge output terminals - each pair drives one motor terminal; include integrated freewheeling diodes for inductive kickback protection |
| 8 | COD | Coding input - selects DI1/DI2 or IN1/IN2 as fault-reset trigger; GND = use DI1/DI2; VCC = use IN1/IN2 |
| 9,10,11,12 | PGND (metal slug) | Power ground plane connection - soldered to large PCB copper area to minimize RDS(ON) error and thermal resistance |
| 17 | CP | Charge-pump output - decoupled with ≤33 nF capacitor to stabilize gate drive voltage during PWM transitions |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables full N-channel high-side drive without external bootstrap components - reduces BOM count and layout complexity |
| Current limiting with blanking | 6.5 A ±20% limit + 12–21 μs blanking window - prevents false tripping during PWM turn-on transients |
| Dual disable inputs (DI1/DI2) | Independent hardware shutdown paths - supports redundant safety architecture per ISO 26262 requirement |
| Diagnostic status flag (SF) | Open-drain output with stored-fault memory - allows host MCU to detect and log faults even after power cycle interruption |
| Undervoltage lockout | 4.15 V turn-off / 4.65 V turn-on with 150 mV hysteresis - prevents erratic operation during battery brownout conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33886 | Higher 10 A continuous current rating; integrated current sense output; no COD pin; different pinout and package (SOIC-36) | Used where higher current and analog current feedback are required - e.g., power seat lumbar support | Select MC33886 when >5 A load capability or analog current monitoring is needed; not pin-compatible with MC33186HVW2 |
| VNHD7008AY | 42 V max supply; SPI interface instead of parallel logic inputs; built-in watchdog timer; SO-20 package | Preferred in systems requiring diagnostics via serial bus and enhanced functional safety features (ASIL-B ready) | Choose VNHD7008AY for SPI-based control architectures and ISO 26262-compliant designs; logic interface and fault reporting differ significantly |
Compared with MC33186HVW2, MC33886 offers higher current capacity but lacks coding input flexibility and uses a larger package, while VNHD7008AY replaces parallel control with SPI and adds watchdog functionality - making MC33186HVW2 optimal for cost-sensitive, logic-driven 5 A motor control where proven thermal performance and simple truth-table operation are prioritized.

FAQ
What is the maximum safe operating voltage for MC33186HVW2 in automotive applications?
The MC33186HVW2 is rated for static operation up to 28 V and dynamic (transient) operation up to 40 V per ISO 7637-2 Pulse 5a. For continuous 12 V or 24 V system use, design must apply thermal derating above 28 V - confirmed by junction temperature calculation using RθJC = 2.0 °C/W and measured case temperature. The MC33186HVW2 datasheet specifies VBAT = 5.0–28 V as the parametric range.
How does the COD pin affect fault recovery behavior in MC33186HVW2?
The COD pin on MC33186HVW2 selects which input pair resets stored faults: when grounded, DI1/DI2 transitions reset the status flag (SF); when tied to VCC, IN1/IN2 transitions perform reset. This allows flexible integration with different controller architectures - for example, safety-critical systems may assign DI1/DI2 to dedicated hardware watchdog signals while reserving IN1/IN2 for functional commands. The MC33186HVW2 truth table (Table 4) explicitly defines these modes.
Can MC33186HVW2 drive inductive loads without external flyback diodes?
Yes, MC33186HVW2 integrates freewheeling diodes across both OUT1 and OUT2 outputs, eliminating the need for external flyback diodes in standard H-bridge configurations. These diodes are rated for 3.0 A forward current (VF ≤ 2.0 V) and 2.0–5.0 μs reverse recovery time. However, a minimum 47 μF capacitor at VBAT (Pins 4/5/16) remains mandatory to absorb inductive energy and prevent supply rail collapse during recirculation - a requirement explicitly stated in the MC33186HVW2 datasheet Section "PIN CONNECTIONS".
What is the thermal performance difference between MC33186HVW2 and MC33186HVW1?
MC33186HVW2 and MC33186HVW1 share identical die, electrical specifications, and thermal characteristics - including RθJC = 2.0 °C/W and RθJA = 29 °C/W (2s2p board). The only distinction is packaging compliance: MC33186HVW2 carries the VW suffix indicating Pb-free (RoHS-compliant) finish per JEDEC J-STD-020C, while MC33186HVW1 is the legacy leaded version. Both use the same 20-pin HSOP-EP package outline (98ASH70702A) and require identical PCB land patterns and thermal vias.
Does MC33186HVW2 support 20 kHz PWM switching as stated in its features?
The MC33186HVW2 supports up to 20 kHz maximum switching frequency only during current-limitation mode (per Table 3, "Maximum Switching Frequency During Current Limitation"), not during normal operation. Its specified PWM frequency for motor control is 10 kHz (Table 3, "PWM frequency"). Exceeding 10 kHz in normal operation risks exceeding safe SOA limits due to increased switching losses - the 20 kHz rating applies solely to the internal current-limit comparator's response bandwidth, not usable PWM carrier frequency. This distinction is clearly documented in the MC33186HVW2 datasheet Section "ELECTRICAL CHARACTERISTICS".
