Product details
Overview
MC33186DH2R2 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 5.0 A continuous DC load current at TC < 100 °C and supporting PWM operation up to 10 kHz in automotive and industrial motion control systems.
For engineers reviewing the MC33186DH2R2 datasheet, MC33186DH2R2 pinout, MC33186DH2R2 application, or MC33186DH2R2 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 covering overtemperature, short-circuit, overvoltage (up to 40 V), and undervoltage lockout.
Technical Context
The MC33186DH2R2 implements a fully integrated half-bridge pair with freewheeling diodes, driven by internal logic that interprets TTL/CMOS-compatible IN1/IN2 signals under DI1/DI2 enable control. Its charge-pump circuit sustains gate drive above VBAT across the full 5.0–28 V operating range, enabling stable high-side switching without external bootstrap components.
Protection is implemented hierarchically: undervoltage disables outputs when VBAT drops below 4.4 V (typ), overcurrent detection triggers tristate shutdown at ≥8.0 A (high-side) or ≥6.5 A ±20% (low-side), and thermal shutdown activates at 160 °C (typ) with 20 °C hysteresis. Fault status is latched and reported via SF, requiring input edge transitions on DI1/DI2 (or IN1/IN2 if COD = VCC) for recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A at case temperature < 100 °C - defines maximum sustained motor/solenoid drive capability without forced cooling |
| RDS(ON) per Channel | 150 mΩ at 25 °C - determines conduction loss and thermal rise during steady-state operation |
| Supply Voltage Range | 5.0 V to 28 V (static), up to 40 V with derating - supports 12 V and 24 V automotive/industrial battery rails |
| PWM Frequency Support | Up to 10 kHz (with external CP capacitor) - enables precise speed/torque control in brushed DC motor applications |
| Thermal Shutdown Threshold | 160 °C typical, 20 °C hysteresis - ensures safe power stage recovery after transient overload or poor heatsinking |
| Status Flag (SF) | Open-drain, active-low fault indicator with <100 ms response - provides real-time system-level diagnostics for ECU monitoring |
| Input Compatibility | TTL/CMOS logic levels (VINH ≥ 3.4 V, VINL ≤ 1.4 V) - allows direct interfacing with microcontrollers and DSPs without level-shifting |
Pinout & Package
The MC33186DH2R2 is housed in a 20-pin HSOP-EP (Heat Sink Overmolded Package – Exposed Pad) with 1.6 mm pitch, 16.0 mm × 11.0 mm body, and a 12.3 mm × 7.1 mm exposed copper thermal pad soldered directly to PCB ground plane for enhanced heat dissipation. RθJC = 2.0 °C/W enables high-power operation with minimal junction-to-case thermal resistance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AGND | Analog ground reference - must be short-traced to PGND to minimize noise coupling into internal logic and protection comparators |
| 2 | SF | Open-drain status flag - pulled low during any fault (overtemp, overcurrent, undervoltage); requires external pull-up for MCU interrupt or LED indication |
| 3, 13 | IN2, DI1 | Direction and disable control inputs - IN2 sets motor direction; DI1 enables/disables output stage; both TTL/CMOS compatible with hysteresis |
| 4, 5, 16 | VBAT | Main power supply pins - internally split to feed left/right high-sides and analog core; must be paralleled on PCB with ≥47 μF bulk capacitance |
| 6, 7, 14, 15 | OUT1, OUT2 | H-bridge power outputs - each includes integrated freewheeling diode; capable of sinking/source 5.0 A continuously with low RDS(ON) |
| 8 | COD | Coding input - selects DI1/DI2 or IN1/IN2 as reset trigger for latched faults; GND = DI-based reset, VCC = IN-based reset |
| 9, 10, 11, 12 | PGND | Power ground terminals - connected to exposed metal slug; must be low-inductance, wide-copper connection to PCB ground plane for thermal and EMI performance |
| 17 | CP | Charge-pump output - decoupled with up to 33 nF capacitor to stabilize gate drive voltage and support full PWM frequency range |
Key Features
| Feature | Design Value |
|---|---|
| Integrated SMARTMOS Power Stage | Monolithic integration of gate drivers, protection logic, and low-RDS(ON) MOSFETs eliminates discrete BOM and layout complexity |
| Dual Independent Disable Inputs (DI1/DI2) | Enables hardware-level safety interlocks - either input can independently force outputs to high-impedance state regardless of IN1/IN2 state |
| Latched Fault Reporting with Edge-Triggered Reset | Ensures no fault goes unobserved; reset requires defined voltage transition on DI1/DI2 (or IN1/IN2), preventing spurious recovery |
| Current Limitation with Blanking Time | 6.5 A ±20% trip threshold + 12–21 μs blanking window prevents false triggering during PWM turn-on transients |
| Stable Operation with Minimum 47 μF VBAT Capacitance | Guarantees immunity to supply rail collapse during high-current recirculation, protecting IC from latch-up or damage |

FAQ
What is the maximum continuous current rating for the MC33186DH2R2?
The MC33186DH2R2 supports 5.0 A continuous DC load current when case temperature (TC) remains below 100 °C. This rating assumes proper PCB thermal design using the exposed pad and adequate copper area. At higher ambient temperatures or reduced heatsinking, derating applies per the thermal curves in the datasheet. The MC33186DH2R2 achieves this with 150 mΩ RDS(ON) per channel at 25 °C, ensuring low conduction losses.
Does the MC33186DH2R2 require an external charge-pump capacitor?
Yes, the MC33186DH2R2 requires an external capacitor (up to 33 nF) between CP (Pin 17) and PGND to stabilize the internal charge pump and enable full PWM frequency operation up to 10 kHz. While the device can operate without it, omitting the capacitor reduces maximum switching speed, increases timing jitter, and degrades gate drive strength - especially at lower VBAT. The MC33186DH2R2 datasheet specifies 33 nF as optimal for consistent 20 kHz maximum switching during current limitation.
How does the fault reset mechanism work on the MC33186DH2R2?
The MC33186DH2R2 latches faults (overtemperature, overcurrent, undervoltage) and holds SF low until a valid reset edge occurs. If COD is grounded, a falling edge on DI1 or rising edge on DI2 resets the fault. If COD is tied to VCC, reset requires a falling edge on IN1 or rising edge on IN2. This dual-mode reset prevents accidental recovery and ensures deliberate system intervention. The MC33186DH2R2 truth table (Table 4) defines all 14 device states, including reset conditions.
What is the purpose of the COD pin on the MC33186DH2R2?
The COD (Coding) pin on the MC33186DH2R2 selects the input pair used to clear latched faults: when COD = GND, DI1/DI2 serve as reset triggers; when COD = VCC, IN1/IN2 become the reset inputs. This flexibility allows system designers to assign safety-critical reset functions to dedicated hardware disable lines (DI1/DI2) or integrate reset into normal direction-control logic (IN1/IN2). The MC33186DH2R2 behavior is explicitly defined in Table 1 and Note 8 of the datasheet.
Can the MC33186DH2R2 operate from a 40 V supply?
Yes, the MC33186DH2R2 supports dynamic operation up to 40 V for durations less than 500 ms (e.g., automotive load dump events), but static operation beyond 28 V requires derating of electrical specifications per the Absolute Maximum Ratings table. The MC33186DH2R2 incorporates overvoltage protection up to 40 V at VBAT, safeguarding internal circuitry during transients. For continuous 40 V use, consult NXP's thermal derating guidelines and verify junction temperature stays within 150 °C limit.
