Product details
Overview
MC33186DH1R2 from Freescale Semiconductor 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) MOSFETs, delivering continuous 5.0 A load current (TC < 100 °C), 150 mΩ typical RDS(ON) per output at 25 °C, and PWM operation up to 10 kHz - deployed in automotive seat/mirror actuators and industrial valve positioning systems.
For engineers reviewing the MC33186DH1R2 datasheet, MC33186DH1R2 pinout, MC33186DH1R2 application, or MC33186DH1R2 equivalent, key selection criteria include its 5.0–28 V operating range, integrated overtemperature/overcurrent/undervoltage protection, diagnostic flag (SF), dual disable inputs (DI1/DI2), and HSOP-20 exposed-pad thermal package for high-power motor interface designs.
Technical Context
The MC33186DH1R2 implements a SMARTMOS-based H-bridge with independent high-side and low-side MOSFETs, each featuring 150 mΩ RDS(ON) at 25 °C and freewheeling diodes. Its internal charge pump enables full enhancement of high-side N-channel MOSFETs without external bootstrap components.
Protection architecture includes three-tier fault detection: undervoltage lockout (4.15–4.65 V hysteresis), thermal shutdown (>160 °C junction), and dual overcurrent sensing (8.0 A high-side trip, 6.5 A ±20% low-side current limit with 20.5 µs blanking time). Fault status is reported via open-drain SF pin with <100 ms response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Load Current | 5.0 A at TC < 100 °C - supports sustained motor torque without external heatsink under moderate PCB copper area |
| RDS(ON) (per channel) | 150 mΩ typ @ 25 °C - minimizes conduction loss and self-heating during 5 A operation |
| PWM Frequency Support | Up to 10 kHz - compatible with standard microcontroller PWM outputs for precise speed control |
| Supply Voltage Range | 5.0–28 V (static), 40 V max with derating - covers 12 V/24 V automotive battery rails including load-dump transients |
| Logic Input Compatibility | TTL/CMOS - interfaces directly with 3.3 V or 5 V MCU GPIO without level-shifting |
| Thermal Resistance (RθJC) | 2.0 °C/W - enables efficient heat transfer from die to exposed pad, critical for >3 W power dissipation |
| Status Flag (SF) | Open-drain, active-low - provides MCU-readable fault indication with <100 ms latency for real-time diagnostics |
Pinout & Package
The MC33186DH1R2 is housed in a 20-pin HSOP (Heat Sink Overmolded Package) with exposed thermal pad (12.3 mm × 7.1 mm), optimized for surface-mount thermal management on double-sided PCBs. The metal slug (Pins 9,10,11,12) serves as PGND and primary heat path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AGND | Analog ground reference for internal logic and protection comparators - must be short-traced to PGND |
| 2 | SF | Open-drain status flag - pulled low during faults (overtemp, overcurrent, undervoltage); requires external pull-up |
| 3,13 | IN2, DI1 | Input 2 and Disable 1 - TTL/CMOS-compatible; DI1 forces tristate when high; IN2 controls OUT2 direction |
| 4,5,16 | VBAT | Main supply input (pins internally connected) - requires ≥47 µF bulk capacitor to suppress switching transients |
| 6,7,14,15 | OUT1, OUT2 | H-bridge outputs with integrated freewheeling diodes - drive motor terminals directly; rated for 5 A continuous |
| 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 stabilize gate drive voltage for high-side MOSFETs |
| 9,10,11,12 | PGND (metal slug) | Power ground return and thermal interface - soldered directly to large PCB copper pour for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Charge Pump | Enables full enhancement of high-side N-MOSFETs without external bootstrap circuitry - simplifies layout and improves reliability |
| Triple Fault Protection | Simultaneous monitoring of supply voltage (4.15 V cutoff), junction temperature (>160 °C shutdown), and output current (8 A high-side trip) - prevents catastrophic failure |
| Diagnostic Status Flag (SF) | Single-pin open-drain output reporting all faults with <100 ms latency - reduces MCU GPIO count and enables fast system-level error recovery |
| Configurable Fault Reset Logic | COD pin selects whether DI1/DI2 or IN1/IN2 edges clear stored faults - allows flexible integration with existing MCU control sequences |
| Low-Side Current Limiting | 6.5 A ±20% clamping with 20.5 µs blanking time - protects against inrush and stall currents while maintaining PWM responsiveness |

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 | 45 V max VCC, 6.5 A peak current, integrated current sense; no charge pump - requires external bootstrap for high-side drive | Better suited for higher-voltage industrial motors; lacks integrated diagnostics and thermal shutdown hysteresis | Choose STSPIN840 when voltage margin >28 V is required and external bootstrap design is acceptable |
| VNH7040AS | 41 V max VCC, 10 A peak, SPI interface, embedded current sense; larger SO-16 package with lower thermal resistance (RθJA = 25 °C/W) | Offers digital configuration and telemetry but requires SPI host and more complex firmware integration | Choose VNH7040AS when system-level diagnostics, programmable current limits, or multi-device daisy-chaining are needed |
Compared with STSPIN840 and VNH7040AS, the MC33186DH1R2 delivers simpler analog control, robust passive protection without software overhead, and superior thermal performance in its HSOP-20 exposed-pad package - making it optimal for cost-sensitive, safety-critical DC motor applications where deterministic fault response is essential.

FAQ
What is the maximum continuous current rating for the MC33186DH1R2?
The MC33186DH1R2 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 reduced copper, derating applies per the datasheet thermal curves. The device also features 6.5 A ±20% low-side current limiting and 8.0 A high-side overcurrent shutdown to protect against transient overloads.
Does the MC33186DH1R2 require an external charge pump capacitor?
Yes, the MC33186DH1R2 requires an external capacitor (up to 33 nF) between CP (Pin 17) and GND to stabilize the internal charge pump. While the device can operate without it, omitting the capacitor degrades high-side gate drive strength, reduces maximum PWM frequency, increases switching times, and raises susceptibility to noise-induced misoperation. Freescale specifies 33 nF as optimal for achieving full 10 kHz PWM capability and robust performance across temperature.
How does the status flag (SF) pin function on the MC33186DH1R2?
The SF pin on the MC33186DH1R2 is an open-drain output that goes low during any fault condition - including undervoltage, overtemperature, overcurrent, or short-circuit events. Its response time is typically under 100 ms. After fault clearance, SF returns high only after a valid reset edge on DI1/DI2 or IN1/IN2 (depending on COD pin state). An external pull-up resistor (typically 10 kΩ to VCC) is mandatory for proper logic-level interpretation by the host MCU.
What is the purpose of the COD pin on the MC33186DH1R2?
The COD (Coding) pin on the MC33186DH1R2 determines which input signals reset stored faults: when grounded or left floating, DI1 and DI2 edges clear faults; when tied to VCC, IN1 and IN2 edges perform the reset. This flexibility allows system designers to align fault recovery behavior with existing MCU control architecture - for example, using dedicated disable lines (DI1/DI2) in safety-critical modes or repurposing motor command pins (IN1/IN2) in simpler implementations.
Can the MC33186DH1R2 operate from a 5 V supply?
Yes, the MC33186DH1R2 operates from 5.0 V to 28 V (static), with absolute maximum rating of 40 V for transient conditions. At 5 V, it meets all specified logic thresholds (VINH ≥ 3.4 V, VINL ≤ 1.4 V) and delivers full functionality, including charge pump operation and 5 A current capability - though RDS(ON) increases slightly with lower VGS. The undervoltage lockout activates below 4.15 V, ensuring predictable disable behavior during brown-out.
