Product details
Overview
DRV10975PWP from Texas Instruments is a three-phase, sensorless BLDC motor driver IC with integrated power MOSFETs, designed for 12-V systems delivering up to 1.5-A continuous winding current. It implements proprietary BEMF-based 180° sinusoidal commutation, features an integrated buck/linear step-down regulator (configurable for 3.3 V or 5 V output), and supports I²C, analog, and PWM speed control - enabling ultra-quiet operation in appliance fan and HVAC blower applications.
For engineers reviewing the DRV10975PWP datasheet, DRV10975PWP pinout, DRV10975PWP application, or DRV10975PWP equivalent, key selection considerations include its 24-pin HTSSOP thermal package, sensorless startup capability, integrated overcurrent/UVLO/thermal protection, and flexible interface options including dedicated DIR, FG, and SPEED pins.
Technical Context
The DRV10975PWP uses a proprietary sensorless back-EMF estimation algorithm to enable smooth 180° sinusoidal commutation without Hall sensors or external shunt resistors. Its integrated gate drivers and power MOSFETs achieve total H+L rDS(on) of 250 mΩ (typ), supporting efficient 12-V motor drive with minimal external components.
It incorporates dual regulation architecture: a hysteretic buck converter (47 µH inductor + 10 µF capacitor) for high-efficiency 3.3 V/5 V output, and configurable linear-mode operation (39 Ω resistor + 10 µF capacitor) when external inductors are omitted. The device operates across –40°C to 125°C junction temperature and includes EEPROM-programmable spin-up profiles and motor parameters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 6.5 V to 18 V - supports wide 12-V system tolerances including automotive battery transients and industrial supply variations. |
| Continuous Output Current | 1.5 A winding current - sufficient for mid-power fans and blowers without external heatsinking under typical thermal layout. |
| Total rDS(on) | 250 mΩ (typ) - low conduction loss enables >85% efficiency at full load in 12-V, 1.5-A operation. |
| Regulator Output | Configurable 3.3 V or 5 V - powers internal logic and external microcontrollers; 100-mA buck or 5-mA LDO output capability. |
| Control Interface | I²C + dedicated SPEED/DIR/FG pins - allows both register-level tuning and simple analog/PWM system integration without firmware overhead. |
| Protection Features | UVLO (5.2–5.8 V hysteresis), overcurrent (2–4 A trip), thermal shutdown (150°C), lock detection - eliminates need for discrete protection circuitry. |

Pinout & Package
DRV10975PWP is housed in a thermally enhanced 24-pin HTSSOP (PWP) package with exposed thermal pad (7.80 mm × 6.40 mm), requiring solder connection of the thermal pad to PCB ground plane for reliable thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCP | Charge pump output | Drives high-side gate drivers; requires external 1-µF ceramic capacitor to CPP/CPN for bootstrap operation. |
| CPP / CPN | Charge pump terminals | Form charge pump loop with VCP; must be decoupled with 1-µF ceramic capacitors between CPP and CPN. |
| SW / SWGND | Step-down regulator switch node / ground | SW connects to external inductor/resistor; SWGND is dedicated ground return for regulator switching path to minimize noise coupling. |
| VREG | Buck regulator output & feedback | Provides regulated 3.3 V or 5 V; also serves as feedback point for regulator loop - requires 10-µF bulk capacitor to PGND. |
| V1P8 / V3P3 | Internal 1.8-V core / 3.3-V supply outputs | V1P8 powers digital core (not for external loads); V3P3 supplies internal logic and can source ≤5 mA to external circuits. |
| GND / PGND | Digital/analog ground / power ground | GND handles logic signals; PGND carries high-current motor and regulator return paths - must be separated and joined only at single-point thermal pad. |
| SCL / SDA | I²C clock / bidirectional data | Standard 3.3-V I²C interface (400-kHz compatible); supports real-time register access and EEPROM programming for motor tuning. |
| FG | Frequency generator output | Open-drain tach signal (pulse per commutation cycle); enables closed-loop speed monitoring without additional sensors. |
| SPEED | Speed command input | Accepts 0–3.3 V analog voltage or 1–100 kHz PWM; internal 55-kΩ pulldown enables sleep mode entry at low signal levels. |
| DIR | Direction control input | Logic-level input (0 V = CW, 3.3 V = CCW); controls phase sequence without software intervention. |
| U / V / W | Motor phase outputs | Three half-bridge outputs driving BLDC motor windings; each pair (e.g., UH/UL) shares common PGND connections. |
| VCC | Main power supply input | Primary 6.5–18 V input; powers gate drivers, regulators, and logic - requires 10-µF bulk + 0.1-µF ceramic decoupling near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Sensorless BEMF control | Enables reliable startup and stable rotation without position sensors or external current sense resistors - reduces BOM count and acoustic noise. |
| Configurable step-down regulator | Supports either buck (high-efficiency, 100-mA output) or linear (low-cost, no inductor) modes - adapts to system cost vs. efficiency trade-offs. |
| EEPROM-programmable parameters | Stores motor-specific settings (spin-up profile, BEMF gain, commutation timing) - eliminates factory calibration and enables field updates via I²C. |
| Dedicated FG tach output | Provides hardware-based speed feedback synchronized to commutation events - simplifies closed-loop control versus software-based RPM calculation. |
| Multi-mode power management | Standby (4.5 mA) and sleep (80 µA) versions available - extends battery life in portable HVAC controls and enables always-on sensing in smart appliances. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase sensorless BLDC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV10983PWPR | Higher 2.5-A continuous current rating; supports 4.5–24-V input; adds active freewheeling and enhanced BEMF detection. | Targeted at larger fans and pumps requiring higher torque margin and wider input range. | Select when motor load exceeds 1.5 A or system voltage exceeds 18 V; note larger thermal footprint and different pinout. |
| MP6532GQ-Z | Monolithic 3-A driver with integrated 12-V LDO; no EEPROM; fixed 120° commutation (not sinusoidal). | Cost-optimized for basic fan control where acoustic noise is less critical than BOM cost. | Choose for high-volume, price-sensitive designs accepting higher EMI and audible noise; verify mechanical compatibility - QFN-24 vs HTSSOP-24. |
Compared with DRV10975PWP, DRV10983PWPR offers higher current headroom and extended voltage range but requires PCB redesign due to non-pin-compatible layout and larger thermal pad. MP6532GQ-Z provides lower system cost and simpler layout but sacrifices sinusoidal drive benefits, resulting in measurable acoustic and torque ripple penalties in noise-sensitive applications.

FAQ
What is the maximum continuous motor current supported by the DRV10975PWP?
The DRV10975PWP supports 1.5-A continuous winding current with peak capability up to 2 A. This rating assumes proper PCB thermal design using the exposed thermal pad, ambient temperature ≤85°C, and operation within the 6.5–18-V input range. Exceeding 1.5 A continuously risks thermal shutdown activation unless board-level copper area and airflow are significantly enhanced beyond reference layout guidelines.
Does the DRV10975PWP require an external current sense resistor?
No, the DRV10975PWP does not require an external current sense resistor. It implements internal overcurrent protection using MOSFET rDS(on) monitoring, with a trip threshold of 2–4 A (phase-to-phase). An optional external sense resistor can be added solely for diagnostic power monitoring via I²C registers - it is not needed for protection or commutation control.
How does the DRV10975PWP achieve sensorless commutation without Hall effect sensors?
The DRV10975PWP uses Texas Instruments' proprietary back-EMF (BEMF) detection algorithm that samples motor phase voltages during PWM off-times to estimate rotor position. It combines this with continuous sinusoidal 180° commutation and adaptive BEMF comparator hysteresis (50 mV) to maintain stable rotation from standstill through full speed - eliminating Hall sensors while reducing acoustic noise versus trapezoidal methods.
Can the DRV10975PWP operate with a 5-V microcontroller I²C interface?
Yes, the DRV10975PWP's SCL and SDA pins are 3.3-V tolerant with VI²C_H = 2.2 V minimum and VI²C_L = 0.6 V maximum, making them compatible with standard 3.3-V or 5-V microcontrollers when used with appropriate level-shifting or pull-up configuration. TI recommends pulling SCL/SDA to V3P3 (3.3 V) rather than VCC to ensure reliable signaling and avoid exceeding absolute maximum ratings.
What is the purpose of the V1P8 and V3P3 pins on the DRV10975PWP?
V1P8 is the internal 1.8-V digital core supply output - it powers the logic and must be decoupled to GND with a 1-µF capacitor but is not intended to drive external loads. V3P3 is a 3.3-V LDO output capable of sourcing up to 5 mA to external circuitry (e.g., MCU I/O or sensor bias), configurable via register to match system voltage requirements and reduce need for external regulators.
