Product details
Overview
DRV10983QPWPRQ1 from Texas Instruments is an automotive-grade, three-phase sensorless BLDC motor driver with integrated power MOSFETs, delivering 2-A continuous winding current and supporting 6.2 V to 28 V motor operation. It features a proprietary BEMF-based 180° sinusoidal commutation scheme, integrated 5-V buck regulator and 3.3-V/1.8-V LDOs, and I²C/SPEED/DIR/FG interface - deployed in seat ventilation fans and HEV battery cooling systems.
For engineers reviewing the DRV10983QPWPRQ1 datasheet, DRV10983QPWPRQ1 pinout, DRV10983QPWPRQ1 application, or DRV10983QPWPRQ1 equivalent, key selection considerations include sensorless startup reliability, load-dump tolerance up to 45 V, configurable PWM slew rate for EMI control, thermal shutdown at 150°C, and AEC-Q100 Grade 1 qualification (–40°C to 125°C ambient).
Technical Context
The DRV10983QPWPRQ1 implements a closed-loop, sensorless BEMF estimation algorithm with initial position detection to prevent back-spin at startup, enabling smooth commutation without Hall sensors. Its 180° sinusoidal drive minimizes torque ripple and acoustic noise in low-external-component fan/pump applications.
It integrates a hysteretic buck regulator (configurable with 47 µH inductor or 39 Ω resistor) delivering 5 V @ 100 mA (switching mode) or 5 mA (linear mode), plus dedicated 3.3-V LDO (20 mA max) and 1.8-V core LDO. Protection includes phase-to-phase/phase-to-GND overcurrent detection, lock detection with 0.3 s entry / 5 s release, UVLO with 200 mV hysteresis, and anti-voltage surge (AVS) response to load dump events.

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 |
|---|---|---|---|
| DRV10987QPWPRQ1 | Higher 3-A continuous current rating; identical pinout and feature set; supports same 6.2–28 V range and AEC-Q100 Grade 1 | Targeted at higher-torque pumps/fans requiring >2-A drive; shares same EEPROM tuning flow and I²C register map | Select when motor winding resistance demands >2-A RMS current or peak torque margin is critical |
| MP6532GQ-P | Non-automotive grade; no AEC-Q100 qualification; lacks integrated buck regulator; requires external 3.3-V supply and current-sense resistor | Cost-sensitive industrial fans where automotive qualification and integrated power are not required | Choose only for non-automotive designs with existing 3.3-V rail and tolerance for added external components |
Compared with DRV10987QPWPRQ1, the DRV10983QPWPRQ1 offers lower current capability but identical integration and qualification - making it optimal for space-constrained, cost-sensitive automotive fans. Against MP6532GQ-P, it delivers superior automotive readiness, reduced component count, and self-contained power regulation at the expense of higher unit cost.

FAQ
What is the maximum continuous motor current supported by the DRV10983QPWPRQ1?
The DRV10983QPWPRQ1 supports 2-A continuous winding current with 3-A peak capability. This is enabled by its integrated MOSFETs with total H+L rDS(on) of 250 mΩ at 25°C and 325 mΩ at 125°C. The device sustains this current across its full operating ambient range of –40°C to 125°C, provided thermal management (e.g., PCB copper area, thermal vias to ground plane) meets the RθJB = 14.8°C/W specification.
Does the DRV10983QPWPRQ1 require external current-sense resistors for overcurrent protection?
No, the DRV10983QPWPRQ1 does not require external current-sense resistors. It implements internal overcurrent protection that monitors phase-to-phase, phase-to-GND, and phase-to-vCC short conditions using integrated sensing. The protection triggers at 3.5–5.5 A depending on condition and temperature, and is documented in the Electrical Characteristics table under IOC_limit_HS and IOC_limit_LS.
How does the DRV10983QPWPRQ1 handle load dump conditions in automotive systems?
The DRV10983QPWPRQ1 handles load dump by entering protection mode when VCC exceeds 28.5–30 V (rising threshold), clamping operation until VCC falls below 27.7–28.8 V (falling threshold). It tolerates up to 45 V at slew rates <1 V/µs without damage, per AEC-Q100 stress testing. This Anti-Voltage Surge (AVS) function is fully integrated and requires no external TVS diodes for basic compliance.
Can the DRV10983QPWPRQ1 operate without an external microcontroller?
Yes, the DRV10983QPWPRQ1 can operate autonomously using its dedicated SPEED and DIR pins for analog/PWM speed control and direction selection, plus FG for tach feedback. EEPROM stores startup profiles and motor parameters, enabling standalone operation. I²C is optional for tuning or diagnostics - not required for basic motor control.
What are the power supply requirements for the DRV10983QPWPRQ1's integrated regulators?
The DRV10983QPWPRQ1's buck regulator requires either a 47 µH inductor + 10 µF output capacitor (for 5-V @ 100 mA) or a 39 Ω resistor + 10 µF capacitor (for 5-V @ 5 mA). V1P8 and V3P3 each require 1 µF capacitors to GND. All regulators derive from VCC (6.2–28 V), and V3P3 may power external 3.3-V logic like FG/DIR pull-ups, up to 20 mA total load.
