Product details
Overview
DRV10983PWP from Texas Instruments is a three-phase, sensorless BLDC motor driver IC with integrated 24-V MOSFETs, delivering 2-A continuous winding current and featuring a proprietary BEMF-based 180° sinusoidal commutation scheme for ultra-low acoustic noise in appliance fan and HVAC blower applications.
For engineers reviewing the DRV10983PWP datasheet, DRV10983PWP pinout, DRV10983PWP application, or DRV10983PWP equivalent, key selection criteria include its 8–28-V input range, integrated 5-V/3.3-V step-down regulator, I²C + analog/PWM speed interface, DIR-controlled bidirectional operation, and thermally enhanced HTSSOP-24 package with exposed thermal pad.
Technical Context
The DRV10983PWP implements a closed-loop sensorless control architecture that estimates rotor position via back-EMF zero-crossing detection with configurable hysteresis (50 mV), enabling smooth sinusoidal drive without Hall sensors or external current sense resistors. Its commutation logic dynamically adapts to motor parameters stored in on-chip EEPROM or updated via I²C registers.
It integrates dual regulation paths: a buck switching regulator (47 µH inductor, 10 µF output cap) delivering up to 100 mA at 5 V or 3.3 V, and a linear mode fallback; plus internal 1.8-V digital core (V1P8) and power ground (PGND) separation for noise immunity. Protection includes phase-to-phase overcurrent (4 A typ), UVLO (7.4 V rise), thermal shutdown (150 °C), and lock detection with 0.3-s entry / 5-s release timing.

Pinout & Package
DRV10983PWP is housed in a thermally enhanced 24-pin HTSSOP (PWP) package measuring 7.80 mm × 6.40 mm with an exposed bottom thermal pad that must be soldered to the PCB ground plane for proper thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCP, CPP, CPN | Charge pump supply | Generates gate drive voltage > VCC for high-side MOSFETs; requires 1-µF ceramic capacitor between CPP and CPN. |
| SW, SWGND | Buck regulator switch node | Connects to external 47-µH inductor and 10-µF output capacitor; SWGND is dedicated ground return for regulator switching loop. |
| VREG | Buck regulator feedback/output | Provides regulated 5 V or 3.3 V; also serves as feedback point for output voltage regulation and load sensing. |
| V3P3, V1P8 | Internal LDO outputs | V3P3 supplies 3.3 V at up to 5 mA for external circuits; V1P8 supplies 1.8 V digital core voltage (not for external loads). |
| U, V, W | Motor phase outputs | Three half-bridge outputs driving BLDC motor windings; each pair (e.g., U1/U2) connects to one motor phase terminal. |
| SCL, SDA | I²C interface | Standard 3.3-V tolerant bidirectional bus; supports register read/write and EEPROM programming for motor tuning. |
| SPEED, DIR, FG | Discrete control & feedback | SPEED accepts 0–3.3 V analog or 1–100 kHz PWM; DIR sets rotation direction; FG outputs open-drain tach signal (5 mA sink). |
| GND, PGND | Ground references | GND = digital/analog reference; PGND = separate high-current power ground for motor and regulator return paths to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Sensorless BEMF control | Proprietary algorithm eliminates need for Hall sensors or external current sense resistors while maintaining stable startup and low-speed operation. |
| Configurable spin-up profile | EEPROM-stored acceleration ramp, start torque, and open-loop duration enable optimization for diverse motor inertias and loads. |
| Dual regulation modes | Switch-mode (buck) or linear-mode operation selectable via VregSel; reduces BOM count by eliminating need for external regulators. |
| Low-power standby/sleep | Standby mode draws 3 mA (DRV10983); sleep mode draws 180 µA (DRV10983Z) - extends battery life or reduces idle power in always-on systems. |
| Comprehensive fault protection | Integrated UVLO, overcurrent (phase-to-phase), thermal shutdown, lock detection, and voltage surge protection prevent damage during abnormal operating conditions. |

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 |
|---|---|---|---|
| DRV10983ZPWP | Sleep mode version with 180 µA quiescent current vs. 3 mA standby; identical pinout, registers, and motor control features. | Preferred for battery-powered or energy-harvested systems requiring ultra-low idle power; not suitable when external MCU must remain powered continuously. | Select DRV10983ZPWP when regulator must be disabled during idle; otherwise DRV10983PWP supports always-on MCU operation. |
| MP6532GQ-P | Monolithic 3-phase driver with 1.5-A continuous current, no integrated regulator, and simpler analog-only interface (no I²C or EEPROM). | Targeted at cost-sensitive, fixed-profile fan applications without need for field tuning or multi-voltage regulation. | Choose MP6532GQ-P only if motor parameters are static and external 3.3-V supply exists; lacks DRV10983PWP's diagnostic visibility and flexibility. |
Compared with DRV10983ZPWP, the DRV10983PWP enables continuous regulator operation for external MCU powering but consumes 17× more idle current; compared with MP6532GQ-P, it adds I²C configurability and integrated regulation at the cost of higher BOM complexity and price.

FAQ
What is the maximum continuous motor current supported by the DRV10983PWP?
The DRV10983PWP supports 2-A continuous winding current with peak capability up to 3 A. This rating assumes operation within recommended thermal limits (TJ ≤ 125°C) and proper PCB layout with thermal pad soldered to ground plane. The total H+L rDS(on) of 250 mΩ at 25°C ensures low conduction losses under this load, making DRV10983PWP suitable for mid-power fans and blowers without auxiliary cooling.
Does the DRV10983PWP require an external current sense resistor?
No, the DRV10983PWP does not require an external current sense resistor. It implements phase-to-phase overcurrent protection using internal MOSFET voltage monitoring and provides lock detection via BEMF signal analysis. An optional external sense resistor can be added only if precise real-time power monitoring is needed - the DRV10983PWP itself measures and reports motor current via I²C registers MotorCurrent1 and MotorCurrent2.
How does the DRV10983PWP achieve ultra-low acoustic noise?
The DRV10983PWP achieves ultra-low acoustic noise through its proprietary sensorless 180° sinusoidal commutation scheme, which minimizes torque ripple and eliminates the pure-tone whine common in trapezoidal drives. By continuously estimating rotor position from back-EMF zero crossings and applying smooth voltage waveforms to U/V/W phases, DRV10983PWP reduces audible noise by >15 dB(A) compared to conventional six-step control - critical for consumer appliance applications.
Can the DRV10983PWP operate without an external microcontroller?
Yes, the DRV10983PWP can operate autonomously using its dedicated SPEED and DIR pins for analog/PWM speed command and direction control, respectively. Its internal EEPROM stores motor parameters and spin-up profiles, allowing full motor operation without I²C communication. However, I²C access is required for initial tuning, real-time diagnostics, or dynamic parameter updates - the DRV10983PWP functions as a standalone driver once configured.
What is the purpose of the V1P8 pin on the DRV10983PWP?
The V1P8 pin on the DRV10983PWP outputs a regulated 1.8-V supply for the internal digital core logic. It is not intended to power external components - the datasheet explicitly states it is "not specified to drive external loads." A 0.1-µF ceramic capacitor must be placed between V1P8 and GND for local decoupling. This dedicated rail isolates sensitive digital circuitry from motor switching noise, ensuring robust register and EEPROM operation across temperature and load conditions.
