Product details
Overview
DRV8262DDVR from Texas Instruments is a 44-pin HTSSOP-packaged dual/single H-bridge motor driver IC supporting 4.5V–60V supply, ±4% current sense accuracy via IPROPI outputs, and up to 32A peak output in single H-bridge mode with top-side thermal pad (DDV package). It drives brushed-DC motors, bipolar stepper motors, or thermoelectric coolers in industrial motion control systems.
For engineers reviewing the DRV8262DDVR datasheet, DRV8262DDVR pinout, DRV8262DDVR application, or DRV8262DDVR equivalent, key selection criteria include thermal pad orientation (top-side), dual vs. single H-bridge configuration via MODE1/MODE2, programmable off-time (7–32μs), integrated high-side current sensing, and OCP thresholds differing by package (16A/32A peak for DDV).
Technical Context
The DRV8262DDVR implements two independent H-bridge power stages with N-channel MOSFETs driven by an internal charge pump enabling 100% duty cycle operation. Its dual-mode architecture supports either two independent brushed-DC motors (dual H-bridge) or one high-current motor (single H-bridge with paralleled bridges), selected by MODE1 logic level.
Current regulation uses fixed off-time PWM chopping with externally adjustable VREF threshold and integrated high-side current mirroring (AIPROPI = 212 μA/A). Protection includes VM UVLO (4.25V nominal), charge pump undervoltage detection, cycle-by-cycle overcurrent protection (OCPM-selectable latch/auto-retry), and thermal shutdown at 150°C with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 4.5V to 60V - supports wide-input industrial DC bus and battery systems without external regulators. |
| Peak output current (single H-bridge) | 32A - enables high-torque brushed-DC motor drive with DDV package's top thermal pad for heatsink coupling. |
| RDS(ON) (HS+LS, single mode) | 50mΩ - low conduction loss reduces heat generation at 20A RMS in typical 24V applications. |
| Current sense accuracy | ±4% at 40–100% rated current - enables reliable stall detection and closed-loop current limiting without external shunts. |
| PWM off-time options | 7 / 16 / 24 / 32μs - configurable via TOFF pin to optimize trade-off between ripple, efficiency, and acoustic noise. |
| Sleep current | 3μA - ultra-low quiescent draw preserves battery life in always-on embedded motion systems. |
| Logic compatibility | 1.8V / 3.3V / 5.0V inputs - interoperable with microcontrollers and FPGAs across voltage domains without level shifters. |
Pinout & Package
DRV8262DDVR uses a 44-pin HTSSOP package with exposed thermal pad on the top surface (DDV variant), optimized for direct heatsink mounting. Thermal pad must be soldered to PCB copper pour or external heatsink for rated current performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 | Control input | Accepts PH/EN or PWM interface signals; MODE2 selects mode; determines bridge direction and enable timing. |
| OUT1–OUT4 | Motor winding output | Four half-bridge outputs; configured as two independent H-bridges (dual mode) or paralleled into one 32A H-bridge (single mode). |
| IPROPI1, IPROPI2 | Analog current sense output | Each sources 212μA per amp of high-side current; ±4% accuracy enables shuntless load monitoring and regulation feedback. |
| VREF1, VREF2 | Current limit reference input | Set current trip threshold (0.05–3.3V); tied together in single H-bridge mode; supports dynamic current scaling. |
| nFAULT | Open-drain fault indicator | Asserts low on UVLO, OCP, OTSD, or CPUV; requires external pull-up; cleared by nSLEEP low pulse in latch-off mode. |
| nSLEEP | Power management input | High = active; low = 3μA sleep mode; falling edge resets latched faults; wake-up time <1ms. |
| MODE1, MODE2 | Configuration select | MODE1 = H-bridge count (high = single); MODE2 = interface type (low = PH/EN, high = PWM). |
| VM, PGND12, PGND34 | Power distribution | VM connects to 4.5–60V supply; separate PGND pins isolate current return paths for EMI reduction and thermal management. |
| VCP, CPH, CPL | Charge pump network | Generates gate drive voltage >VM for high-side N-FETs; requires 1μF X7R cap (VCP–VM) and 0.1μF X7R cap (CPH–CPL). |
| VCC, DVDD, GND | Logic supply | VCC powers internal logic (3.05–5.5V); DVDD is internal LDO output (4.75–5.25V); GND is signal ground reference. |
Key Features
| Feature | Design Value |
|---|---|
| Top-side thermal pad (DDV) | Enables direct mechanical and thermal coupling to external heatsink-critical for sustaining 32A peak in single H-bridge mode. |
| Integrated high-side current mirror | Eliminates need for external shunt resistors; saves PCB area and BOM cost while delivering ±4% sensing accuracy at full scale. |
| Configurable PWM off-time | Four discrete settings (7/16/24/32μs) allow optimization of motor torque ripple, efficiency, and audible noise without firmware changes. |
| Smart fault recovery | OCPM pin selects between auto-retry (transient overload recovery) or latch-off (persistent fault isolation), enhancing system robustness. |
| Spread spectrum clocking | Reduces EMI peak emissions by dithering internal digital and charge pump clocks-helps meet CISPR-22/32 Class B standards. |

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 |
|---|---|---|---|
| DRV8256PAPR | 40V max VM, 20A peak (QFN-32), no integrated current sense output, requires external shunt. | Lower voltage/current capability; suited for cost-sensitive 24V robotics but lacks shuntless sensing. | Select when budget constraints outweigh need for integrated sensing and 60V operation. |
| MP6550GQ-Z | 60V max VM, 10A peak (QFN-28), built-in current sense amplifier (not mirror), ±2% accuracy, no TOFF configuration. | Smaller package and higher sensing accuracy, but lower current and fixed PWM timing limit flexibility. | Select when PCB space is critical and 10A peak suffices; avoid if >16A per bridge or programmable off-time required. |
Compared with DRV8262DDVR, DRV8256PAPR offers lower cost and smaller footprint but sacrifices 60V support and shuntless sensing; MP6550GQ-Z delivers superior current accuracy in a compact QFN but cannot match DRV8262DDVR's 32A peak or configurable off-time-making DRV8262DDVR optimal for high-power, thermally demanding industrial motion.

FAQ
What is the maximum continuous current DRV8262DDVR can deliver in single H-bridge mode?
The DRV8262DDVR supports up to 32A peak current in single H-bridge mode at 24V and 25°C ambient, but continuous current depends on PCB thermal design, ambient temperature, and airflow. With proper heatsinking to the top-side thermal pad, sustained RMS current reaches 20A per the DDV package's recommended operating conditions-verified by TI's thermal simulations using a 4-layer 2oz Cu board with 13×5 thermal vias.
How does the DRV8262DDVR implement current sensing without external shunt resistors?
The DRV8262DDVR integrates high-side MOSFET current mirroring, where IPROPI1 and IPROPI2 each source 212μA per amp of high-side current (AIPROPI = 212 μA/A) with ±4% accuracy from 40% to 100% of full scale. This analog output is converted to voltage using an external RIPROPI resistor, eliminating shunt resistors while maintaining precision for regulation and diagnostics.
Can DRV8262DDVR drive a bipolar stepper motor, and how is it configured?
Yes, DRV8262DDVR drives bipolar stepper motors in dual H-bridge mode: OUT1/OUT2 control phase A and OUT3/OUT4 control phase B. MODE1 must be low, and IN1–IN4 accept standard step/direction or PWM signals. Current regulation is set independently per bridge via VREF1/VREF2, enabling microstepping compatibility when paired with external indexer logic.
What is the function of the top-side thermal pad on the DRV8262DDVR package?
Unlike bottom-exposed DDW variants, the DRV8262DDVR's top-side thermal pad is designed for direct mechanical and thermal attachment to an external heatsink-enabling efficient heat extraction critical for sustaining 32A peak current. TI specifies RθJC(top) = 0.7°C/W for the DDV package, making heatsink coupling essential for thermal compliance above 10A RMS.
How does the OCPM pin affect fault behavior in DRV8262DDVR?
The OCPM pin selects fault recovery method: grounded = latch-off (nFAULT stays low until nSLEEP pulse), pulled high = auto-retry (fault clears after 4.1ms timeout). This allows system-level choice between fail-safe shutdown (e.g., medical devices) or self-recovery (e.g., conveyor jams), with no firmware dependency-configurable at power-up via simple resistor tie-off.
