Product details
Overview
DRV10982QPWPRQ1 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 DRV10982QPWPRQ1 datasheet, DRV10982QPWPRQ1 pinout, DRV10982QPWPRQ1 application, or DRV10982QPWPRQ1 equivalent, this page delivers verified technical context, HTSSOP-24 pin mapping, BEMF-based commutation behavior, thermal shutdown thresholds, and I²C-configurable spin-up profiles - all confirmed against TI's SLVSF30A production data sheet.
Technical Context
The DRV10982QPWPRQ1 implements a proprietary sensorless back-EMF estimation algorithm enabling continuous sinusoidal 180° commutation without Hall sensors, reducing acoustic noise and torque ripple. It integrates a hysteretic 5-V buck regulator (configurable with 47 µH inductor or 39 Ω resistor) and dual LDOs (3.3 V/1.8 V) for internal and external circuit power.
Protection architecture includes phase-to-phase, phase-to-GND, and phase-to-VCC overcurrent detection without external sense resistors; lock detection with 0.3 s entry and 5 s release timing; load dump tolerance up to 45 V; and thermal shutdown at 150–180°C with 15–25°C hysteresis - all qualified per AEC-Q100 Rev G.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Motor Drive Current | 2-A continuous, 3-A peak winding current - supports compact fan/pump loads without external current amplification. |
| Supply Voltage Range | 6.2 V to 28 V for motor operation; register settings preserved down to 4.5 V - enables robust start-up under cold-crank conditions. |
| Total rDS(on) | 300 mΩ at 25°C, 400 mΩ at 125°C - defines conduction loss and thermal derating envelope for PCB layout. |
| Control Interface | I²C (up to 400 kHz), analog SPEED input (0–3.3 V), PWM SPEED input (0.1–100 kHz), DIR pin - allows flexible integration with MCU or standalone analog control. |

| Protection Features | UVLO, overcurrent (phase shorts), lock detection, AVS, thermal shutdown - eliminates need for discrete protection circuitry. |
| Regulator Outputs | 5-V buck (100 mA max), 3.3-V LDO (20 mA max), 1.8-V LDO (internal only) - powers MCU, sensors, and logic without external regulators. |
Pinout & Package
Package: HTSSOP-24 (PWP) with exposed thermal pad (7.80 mm × 6.40 mm); thermally enhanced for automotive under-hood use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCP, CPP, CPN | Charge pump network | Generates gate drive voltage > VCC for high-side MOSFETs; requires ceramic capacitor between CPN–CPP and VCP–VCC. |
| U, V, W | Motor phase outputs | Three-phase PWM outputs driving BLDC windings; each pair (e.g., U–V) forms half-bridge leg with integrated FETs. |
| SPEED | Speed command input | Accepts analog (0–3.3 V) or PWM (0.1–100 kHz) signal; determines target commutation frequency and amplitude. |
| DIR | Direction control | Logic-level input (0.6 V / 2.2 V thresholds) selects U→V→W (low) or U→W→V (high) commutation sequence. |
| FG | Tachometer feedback | Open-drain output (3.3 V compatible) pulses at motor electrical frequency - enables closed-loop speed monitoring without external circuitry. |
| VREG, SW, SWGND | Buck regulator interface | VREG = regulated 5-V output node; SW = switching node; SWGND = dedicated power ground - requires 47 µH inductor and 10 µF output cap. |
| V3P3, V1P8, GND, PGND | Power distribution | V3P3 supplies external 3.3-V loads (≤20 mA); V1P8 powers internal digital core; PGND handles high-current motor return; GND is signal reference. |
| Thermal Pad | Thermal & electrical path | Must be soldered to PCB ground plane with ≥4 thermal vias - critical for achieving RθJB = 14.8°C/W and reliable 125°C ambient operation. |
Key Features
| Feature | Design Value |
|---|---|
| Sensorless BEMF control | Eliminates Hall sensors and associated wiring; enables ultra-quiet 180° sinusoidal commutation in space-constrained modules. |
| Configurable slew rate | Four programmable phase edge rates (27–145 V/µs) - balances EMI reduction against switching loss in EMC-sensitive vehicle cabins. |
| Initial position detect | Prevents reverse spin at startup by estimating rotor position before commutation begins - essential for fan/pump reliability. |
| No external sense resistor | Integrated current sensing avoids PCB area, cost, and calibration overhead while maintaining overcurrent protection across all fault modes. |
| EEPROM-tunable profile | Spin-up acceleration, braking, and coast parameters stored in on-chip EEPROM - enables one-time factory tuning per motor variant. |

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 |
|---|---|---|---|
| DRV10983QPWPRQ1 | Same HTSSOP-24 package and pinout; adds configurable current limit and enhanced spin-up diagnostics; higher active current (18 mA vs 15 mA). | Preferred for applications requiring field-serviceable motor parameter tuning or tighter current limiting during startup. | Select DRV10983QPWPRQ1 when diagnostic visibility or adaptive current limiting is required; otherwise DRV10982QPWPRQ1 offers lower system cost. |
| MP6532GQ-P | Monolithic 3-phase driver with 1.5-A continuous rating; no integrated buck regulator; requires external 3.3-V supply; smaller QFN-24 package (4×4 mm). | Suitable for space-constrained, low-power fans where external regulation is already present and thermal margin exceeds 125°C ambient. | Choose MP6532GQ-P only if board area is critical and 5-V buck functionality is redundant; DRV10982QPWPRQ1 provides superior integration and automotive qualification depth. |
Compared with DRV10983QPWPRQ1, the DRV10982QPWPRQ1 trades advanced diagnostics for lower quiescent current and simpler register map; versus MP6532GQ-P, it delivers full power subsystem integration (buck + dual LDOs) and broader AEC-Q100 coverage - making it optimal for cost-sensitive, thermally demanding automotive fan modules.

FAQ
What is the maximum motor supply voltage supported by the DRV10982QPWPRQ1?
The DRV10982QPWPRQ1 supports motor operation up to 28 V. Above this threshold, the device enters load dump protection mode and halts motor drive until VCC falls below 28.8 V. It tolerates transient voltages up to 45 V with slew rate <1 V/µs - confirmed in Section 7.1 Absolute Maximum Ratings of the SLVSF30A datasheet.
Does the DRV10982QPWPRQ1 require an external current-sense resistor?
No, the DRV10982QPWPRQ1 does not require an external current-sense resistor. Its integrated overcurrent protection detects phase-to-phase, phase-to-GND, and phase-to-VCC shorts using internal MOSFET voltage monitoring - a key feature documented in Section 1 Features and Section 8.3.2.3.
How does the DRV10982QPWPRQ1 handle motor startup without position sensors?
DRV10982QPWPRQ1 uses an initial position-detect algorithm that estimates rotor alignment before commutation begins, preventing reverse spin. This sensorless BEMF-based method is detailed in Section 1 Features and Section 8.3.3, enabling reliable startup in fans and pumps.
What are the power supply options for the integrated regulators in the DRV10982QPWPRQ1?
The DRV10982QPWPRQ1 supports two configurations for its 5-V step-down regulator: buck mode (47 µH inductor + 10 µF capacitor) delivering up to 100 mA, or linear mode (39 Ω resistor + 10 µF capacitor) delivering up to 5 mA - specified in Section 8.3.1.1 and Figure 8-1.
Is the DRV10982QPWPRQ1 pin-compatible with other devices in the DRV1098x-Q1 family?
Yes, the DRV10982QPWPRQ1 shares identical HTSSOP-24 (PWP) packaging and pinout with DRV10983QPWPRQ1, enabling drop-in replacement where enhanced diagnostics are not required - verified in TI's orderable addendum and Pin Configuration tables (Section 6).
