Product details
Overview
DRV10975ZPWPR from Texas Instruments is a three-phase, sensorless BLDC motor driver IC with integrated power MOSFETs, designed for 6.5–18 V input systems delivering up to 1.5-A continuous winding current. It implements proprietary BEMF-based 180° sinusoidal commutation, includes an integrated 3.3/5-V step-down regulator, and supports I²C, analog, or PWM speed control - enabling ultra-quiet operation in appliance fan and HVAC blower applications.
For engineers reviewing the DRV10975ZPWPR datasheet, DRV10975ZPWPR pinout, DRV10975ZPWPR application, or DRV10975ZPWPR equivalent, key selection considerations include its sleep-mode supply current (80 µA), total H+L rDS(on) of 250 mΩ, thermal shutdown at 150°C, and HTSSOP-24 package with exposed thermal pad for high-power-density motor control designs.
Technical Context
The DRV10975ZPWPR uses a proprietary sensorless back-EMF estimation algorithm to enable continuous sinusoidal 180° commutation without Hall sensors or external current sense resistors. Its control loop integrates real-time VCC monitoring and phase current sampling to dynamically adjust timing and amplitude for stable spin-up and low-acoustic operation.
It features dual-regulator architecture: a configurable hysteretic buck converter (4.5–5.5 V or 3.06–3.6 V output) capable of 100 mA load, plus dedicated 3.3-V and 1.8-V LDOs for internal logic and optional external circuitry. Protection includes UVLO (5.2–6.5 V rise threshold), overcurrent detection (2–4 A trip), lock detection (0.3 s enter / 5 s release), and thermal shutdown with 10°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 6.5 V to 18 V - supports wide-range 12-V nominal systems including automotive battery transients and industrial DC supplies. |
| Continuous Winding Current | 1.5 A - enables direct drive of small-to-medium BLDC fans without external FETs or heatsinking in compact enclosures. |
| Total H+L rDS(on) | 250 mΩ (typ) - minimizes conduction loss and self-heating during sustained operation at rated load. |
| Sleep Mode Supply Current | 80 µA - allows battery-backed or energy-sensitive systems to maintain motor readiness with negligible standby drain. |
| Step-Down Regulator Output | Selectable 3.3 V or 5 V - powers internal logic and can supply external microcontrollers or sensors without secondary regulators. |
| Operating Junction Temperature | –40°C to 125°C - qualified for harsh environments including enclosed HVAC ducts and appliance motor compartments. |
| BEMF Commutation | Sinusoidal 180° - reduces torque ripple and audible noise versus trapezoidal drives, critical for consumer-grade quiet operation. |
Pinout & Package
DRV10975ZPWPR is housed in a thermally enhanced 24-pin HTSSOP (PWP) package (7.80 mm × 6.40 mm) with exposed thermal pad soldered to PCB ground for efficient heat dissipation. The package supports JEDEC-standard reflow and is RoHS-compliant.
| 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 voltage generation. |
| CPP, CPN | Charge pump terminals | Form charge pump network with VCP; must be decoupled with 1-µF ceramic capacitors between CPP and CPN. |
| SW, SWGND | Step-down regulator switching node and ground | Connects to external 47-µH inductor and 10-µF output capacitor; SWGND must be low-inductance return path for regulator loop. |
| VREG | Step-down regulator output and feedback point | Regulated output (3.3 V or 5 V); also serves as feedback node - requires precise resistor divider if using linear mode configuration. |
| V1P8, V3P3 | Internal LDO outputs | V1P8 (1.8 V) powers digital core; V3P3 (3.3 V) powers analog circuits and may supply external loads ≤5 mA. |
| GND, PGND | Digital/analog and power ground | GND handles logic/communication returns; PGND carries high-current motor and regulator return paths - must be separated and joined at single point. |
| SCL, SDA | I²C interface signals | Support standard/fast-mode I²C (≤400 kHz); open-drain with 5-mA sink capability; require external pull-ups to V3P3. |
| FG | Tachometer output | Open-drain frequency generator output synchronized to motor electrical cycles; used for closed-loop speed verification. |
| SPEED | Speed command input | Accepts 0–3.3 V analog voltage or 1–100 kHz PWM signal; internal 55-kΩ pulldown enables sleep entry when floating. |
| DIR | Direction control input | Logic-level input (0 V = CW, >2.2 V = CCW); no internal pull-up - requires external biasing if driven by open-collector source. |
| U, V, W | Motor phase outputs | Three half-bridge outputs driving BLDC motor windings; each pair (e.g., UH/UL) shares common PGND connection. |
| VCC | Main power supply input | Primary 6.5–18 V input; connects to bulk capacitor (10 µF) and feeds all internal regulators and gate drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Sensorless BEMF control | Eliminates need for Hall sensors or rotor position feedback, reducing BOM count and mechanical complexity in sealed fan modules. |
| No external current sense resistor | Integrated overcurrent protection detects phase faults directly via MOSFET Rds(on) sensing - saves board space and eliminates sense resistor tolerance errors. |
| Configurable sleep mode (80 µA) | Shuts down step-down regulator and digital core during idle, enabling multi-year battery life in smart HVAC actuators or portable appliances. |
| EEPROM-programmable spin-up profile | Stores motor-specific acceleration ramp, start torque, and BEMF gain settings - allows one firmware image to support multiple motor variants. |
| Dual-regulator architecture | Combines buck converter (100 mA) and 3.3-V/1.8-V LDOs to power MCU, sensors, and internal logic from single 12-V rail - avoids discrete regulator ICs. |

FAQ
What is the primary function of the DRV10975ZPWPR?
The DRV10975ZPWPR is a three-phase, sensorless BLDC motor driver IC with integrated power MOSFETs, designed to deliver up to 1.5-A continuous winding current. It executes proprietary BEMF-based 180° sinusoidal commutation, includes an integrated step-down regulator (3.3 V or 5 V), and supports flexible speed control via I²C, analog voltage, or PWM input - all within a single HTSSOP-24 package.
How does the DRV10975ZPWPR achieve ultra-quiet motor operation?
The DRV10975ZPWPR achieves ultra-quiet operation through continuous sinusoidal 180° commutation enabled by its proprietary sensorless BEMF control scheme. This minimizes torque ripple and eliminates the pure-tone acoustics typical of trapezoidal drives. Combined with low 250-mΩ total rDS(on) and optimized spin-up profiles stored in EEPROM, the DRV10975ZPWPR significantly reduces audible noise in fan and blower applications.
What are the key differences between DRV10975ZPWPR and DRV10975PWPR?
The DRV10975ZPWPR operates in sleep mode with 80-µA supply current, shutting down the step-down regulator when idle, while the DRV10975PWPR uses standby mode with 4.5-mA current and keeps the regulator active. This makes DRV10975ZPWPR ideal for battery-powered systems, whereas DRV10975PWPR suits applications needing rapid wake-up and continuous MCU power - both share identical pinout, feature set, and motor control architecture.
Does the DRV10975ZPWPR require an external current sense resistor?
No, the DRV10975ZPWPR does not require an external current sense resistor. It implements integrated overcurrent protection by monitoring MOSFET conduction voltage (rDS(on)) during operation. However, the device provides optional support for an external sense resistor if precise power monitoring or custom current limiting is needed - this is configurable via EEPROM or I²C registers.
What thermal management provisions does the DRV10975ZPWPR include?
The DRV10975ZPWPR includes thermal shutdown protection triggered at 150°C junction temperature with 10°C hysteresis, and is packaged in a thermally enhanced HTSSOP-24 with exposed thermal pad. The datasheet specifies RθJA = 36.1°C/W and RθJC(bot) = 1.1°C/W, requiring the thermal pad to be soldered to a PCB ground plane with multiple thermal vias for effective heat transfer - essential for sustaining 1.5-A continuous operation at 125°C ambient.
