Product details
Overview
DRV10982SQPWPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive three-phase sensorless BLDC motor driver with integrated MOSFETs, delivering 2-A continuous winding current (3-A peak), 300 mΩ total H+L rDS(on) at 25°C, and operation from 6.2 V to 28 V for motor drive - used in seat ventilation fans and HEV battery cooling systems.
For engineers reviewing the DRV10982SQPWPRQ1 datasheet, DRV10982SQPWPRQ1 pinout, DRV10982SQPWPRQ1 application, or DRV10982SQPWPRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and protection specs, and real-world automotive motor control use cases - all specific to the DRV10982SQPWPRQ1 standby-version HTSSOP-24 package.
Technical Context
The DRV10982SQPWPRQ1 implements a proprietary sensorless BEMF-based 180° sinusoidal commutation algorithm enabling ultra-low acoustic noise, with initial position detection to prevent back-spin at startup. It integrates a configurable hysteretic buck regulator (5-V output, up to 100 mA) and dual LDOs (3.3-V/1.8-V) for internal and external circuit power.
It supports flexible speed control via analog voltage, PWM input (0.1–100 kHz), or I²C register writes, while providing TACH feedback on FG and direction control on DIR. Protection includes phase-to-phase/GND/VCC overcurrent detection without external sense resistors, lock detection with 0.3-s entry and 5-s release timing, and load dump tolerance up to 45 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Motor Drive Current | 2-A continuous, 3-A peak winding current - enables direct driving of small automotive fans/pumps without external FETs. |
| Supply Voltage Range | 6.2 V–28 V for motor operation; registers preserved down to 4.5 V - supports cold-crank and load-dump resilience. |
| Total rDS(on) | 300 mΩ @ 25°C, 400 mΩ @ 125°C - defines conduction loss and thermal derating in compact HTSSOP package. |
| Buck Regulator Output | 5-V ±0.5 V, 100 mA max (inductor mode) - powers MCU or sensors without secondary DC/DC. |
| Standby Supply Current | 8.5 mA @ 12 V - low quiescent draw during idle, preserving battery life in always-on vehicle modules. |
| Ambient Temp Range | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin-mounted applications. |
| Protection Features | UVLO, thermal shutdown (150°C trigger), anti-voltage surge, overcurrent (phase-to-phase/GND/VCC), lock detection - eliminates need for discrete protection circuitry. |
Pinout & Package
Package: HTSSOP-24 (PWP) with exposed thermal pad (7.80 mm × 6.40 mm); thermally enhanced for automotive ambient conditions up to 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (23,24) | Power supply input | Primary 6.2–28 V motor supply; supports load dump up to 45 V with automatic protection mode. |
| U/V/W (17–18,19–20,21–22) | Three-phase motor outputs | Integrated half-bridge outputs; each pair drives one motor phase with configurable slew rate (27–145 V/µs). |
| SPEED (13) | Speed command interface | Accepts analog (0–3.3 V) or PWM (0.1–100 kHz) input; enables seamless transition between control modes. |
| DIR (14) | Direction control input | Logic-level input (0.6 V/2.2 V thresholds) selecting U→V→W (low) or U→W→V (high) commutation sequence. |
| FG (12) | Tachometer feedback output | Open-drain pulse output synchronized to motor electrical frequency; compatible with MCU GPIO or dedicated tach inputs. |
| SCL/SDA (10,11) | I²C interface | Standard-mode (≤400 kHz) bidirectional bus for real-time register access, EEPROM programming, and diagnostics. |
| VREG (6) | Buck regulator output/feedback | 5-V regulated output; also serves as feedback node - requires 10 µF ceramic capacitor to PGND. |
| V3P3 (9) | 3.3-V LDO output | Supplies internal logic and can drive external loads ≤20 mA (e.g., pull-ups for I²C or FG). |
| GND (8), PGND (15,16), SWGND (5) | Ground connections | Digital/analog (GND), power (PGND), and buck-switch (SWGND) grounds - must be separated per layout guidelines. |
| Thermal Pad | Thermal and electrical ground | Exposed pad must be soldered to PCB ground plane with ≥4 thermal vias for junction-to-board RθJB = 14.8°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Sensorless BEMF commutation | Proprietary 180° sinusoidal drive eliminates hall sensors and reduces acoustic noise in fan/pump applications. |
| Configurable PWM slew rate | 4-step programmable phase-edge slew (27–145 V/µs) enables EMI optimization without external gate resistors. |
| No external current sense | Integrated overcurrent protection detects phase shorts to GND, VCC, or other phases - removes sense resistor and associated layout area. |
| EEPROM-programmable spin-up | User-customizable start profile stored in on-chip EEPROM - ensures reliable startup across motor variants without firmware update. |
| Flexible power architecture | Buck regulator operates in switching (inductor) or linear (resistor) mode - balances efficiency vs. BOM cost based on system needs. |

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 |
|---|---|---|---|
| DRV10983Q1 | Includes integrated tuning assistant and enhanced startup algorithms; same HTSSOP-24 package and pinout. | Targeted for faster development cycles where TI's tuning guide is leveraged; identical functional scope but optimized for rapid calibration. | Select DRV10983Q1 when design schedule prioritizes quick motor characterization over minimal BOM count. |
| MP6532GQ-Z | Monolithic 3-phase driver with 1.5-A continuous rating, 5.5–35 V operation, and no integrated buck regulator. | Requires external 5-V supply; lacks EEPROM, FG output, and analog/PWM dual-speed interface - simpler but less feature-rich. | Choose MP6532GQ-Z only if system already provides regulated 5-V rail and application does not require tach feedback or programmable startup profiles. |
Compared with DRV10982SQPWPRQ1, DRV10983Q1 offers identical packaging and pin compatibility with added tuning acceleration, while MP6532GQ-Z trades integration (no buck, no EEPROM, no FG) for lower cost and smaller footprint - making DRV10982SQPWPRQ1 optimal for automotive thermal management where integrated power and diagnostics are essential.

FAQ
What is the difference between DRV10982SQPWPRQ1 and DRV10982Q?
The DRV10982SQPWPRQ1 is the standby-version variant with 8.5-mA quiescent current and active buck regulator during idle, whereas DRV10982Q is the sleep-version with 48-μA quiescent current and disabled regulator. Both share identical pinout, protection features, and motor drive capability, but DRV10982SQPWPRQ1 is selected when external circuits (e.g., MCU) require continuous 5-V or 3.3-V supply during standby.
Does DRV10982SQPWPRQ1 require an external current-sense resistor?
No, DRV10982SQPWPRQ1 implements internal overcurrent protection that monitors MOSFET conduction losses - detecting phase-to-phase, phase-to-GND, and phase-to-VCC shorts without any external sense resistor. This reduces BOM count, PCB area, and thermal design complexity in automotive fan and pump modules.
Can DRV10982SQPWPRQ1 operate during automotive load dump events?
Yes, DRV10982SQPWPRQ1 is rated for load dump up to 45 V with controlled slew rate (<1 V/µs). When VCC exceeds 29.2 V, it enters protection mode - halting motor drive while preserving register settings and maintaining internal regulation - then resumes normal operation once VCC falls below 28.2 V, ensuring robustness in 12-V vehicle electrical systems.
What motor control interfaces does DRV10982SQPWPRQ1 support?
DRV10982SQPWPRQ1 supports three independent speed control methods: analog voltage (0–3.3 V) on SPEED pin, PWM signal (0.1–100 kHz) on SPEED pin, and real-time register writes via I²C. Direction is controlled by DIR pin, and speed feedback is provided simultaneously on FG pin and through I²C readback - enabling flexible system architecture choices.
Is the buck regulator in DRV10982SQPWPRQ1 configurable for different output modes?
Yes, the buck regulator in DRV10982SQPWPRQ1 can be configured as either a switching buck (using external 47-µH inductor) delivering up to 100 mA at 5 V, or as a linear regulator (replacing inductor with 39-Ω resistor) delivering up to 5 mA. This allows trade-offs between efficiency and BOM simplicity depending on system power requirements.
