DRV10983QPWPRQ1 Overview
A BLDC motor driver is a power management IC that controls commutation of brushless DC motors without mechanical brushes. The DRV10983-Q1 belongs to the sensorless motor driver family, using back-EMF sensing to determine rotor position and eliminating Hall sensors, which reduces system cost and improves reliability. As a motor driver, it sits in the broader power management IC hierarchy, specifically motor control ICs.
Key features include the integrated 3.5-A peak power stage, a supply range of 8 V to 28 V (24-V battery load-dump tolerant), and dual I2C and PWM control interfaces. Sinusoidal drive waveforms minimize acoustic noise and vibration versus trapezoidal (block) commutation. Protection features include overcurrent, overtemperature shutdown, undervoltage lockout, and lock detection. AEC-Q100 automotive qualification ensures robust performance.
Technically, the DRV10983-Q1 estimates rotor position from motor back-EMF, enabling smooth startup across a wide speed range. The integrated power stage uses low RDS(on) MOSFETs to reduce dissipation, and motor parameters are configurable via I2C for tuning to specific motor characteristics. The HTSSOP exposed pad provides good thermal performance for PCB heat spreading.
Typical applications include automotive cooling fans, oil pumps, water pumps, and HVAC blowers. The I2C interface enables real-time monitoring and configuration valuable in advanced automotive systems.
Design tip: ensure adequate PCB copper area on the exposed pad for heat dissipation, and correctly configure I2C motor parameters to match the specific motor being driven.

Typical Applications
DRV10983QPWPRQ1 is suitable for 6 applications: Automotive Cooling Fans, Automotive Oil and Water Pumps, Automotive HVAC Blowers, Industrial Pumps and Fans, Electric Water Heaters and Circulation Pumps, Automotive Fuel Pumps and Battery Cooling.
Automotive Cooling Fans
The DRV10983QPWPRQ1 fits radiator and condenser fan modules where its 3.5-A peak current covers typical 12-V fan motors and its 8 V to 28 V input range absorbs battery transients. Sinusoidal 180-degree drive reduces fan acoustic noise versus trapezoidal commutation, important for passenger comfort. The I2C interface enables speed reporting and fault diagnostics to the body control module, while AEC-Q100 qualification and -40C to +125C rating meet under-hood mounting requirements.
Recommended
Automotive Oil and Water Pumps
Engine oil pumps and coolant water pumps benefit from the DRV10983QPWPRQ1 sensorless sinusoidal drive, which eliminates Hall sensors in fluid-immersed motor assemblies where sensor reliability is a concern. The 3.5-A peak capability handles pump start-up torque, and integrated overcurrent and lock-detection protection prevents damage from blocked rotors. I2C monitoring provides real-time speed and status feedback for functional-safety diagnostics in modern engine thermal management systems.
Recommended
Automotive HVAC Blowers
HVAC blower motors driven by the DRV10983QPWPRQ1 achieve low acoustic signature through sinusoidal commutation, directly improving cabin NVH. The device supports PWM speed control from the climate controller or I2C-based configuration with soft-start profiles. Its UVLO and overtemperature protection tolerate the harsh under-dash electrical environment, and the 24-HTSSOP exposed-pad package simplifies thermal design in compact blower controller modules operating from the 12-V battery rail.
Recommended
Industrial Pumps and Fans
Although automotive qualified, the DRV10983QPWPRQ1 serves industrial 12/24-V pump and fan systems equally well, where its 28-V maximum supply covers 24-V rails. Sensorless sinusoidal control extends bearing and pump life by reducing torque ripple and vibration. I2C parameter tuning lets one firmware platform support multiple motor SKUs, cutting development cost across product families while the integrated power stage removes external MOSFETs and gate drivers from the BOM.
Recommended
Electric Water Heaters and Circulation Pumps
Circulation pumps in thermal management systems use the DRV10983QPWPRQ1 for quiet, efficient operation at moderate power. The sinusoidal algorithm minimizes pressure pulsation noise in plumbing loops, and the sensorless approach survives condensation-prone environments where Hall wiring fails. Protection features such as overtemperature shutdown and lock detection enable unattended operation, while I2C reporting of speed and supply status integrates into system-level supervisory control via a small host MCU.
Recommended
Automotive Fuel Pumps and Battery Cooling
Low-voltage fuel pump and EV battery cooling fan drivers benefit from the DRV10983QPWPRQ1 robust input range and diagnostics. The device tolerates cranking dips and load-dump transients within its 8 V to 28 V rating, and fault flags over I2C support ASIL-relevant monitoring architectures when paired with a functional-safety MCU. Its integrated current limit protects the wiring harness during rotor stall events common in contaminated fuel pump environments.

Key Differentiators
- Automotive AEC-Q100 qualification (vs DRV10983QPWPR)
- Sinusoidal drive for low acoustic noise (vs MCT8316APWPR)
- I2C configurability and diagnostics (vs DRV10975PWPR)
Design Notes
The 24-HTSSOP exposed pad must be soldered to a copper pour of at least 1 square inch with thermal vias to inner layers. Continuous operation near 3.5-A peak in fan/pump duty cycles can push junction temperature toward the 125C limit; use TI datasheet thermal tables to calculate dissipation from phase resistance and RDS(on) for your motor profile.
Place a 0.1-uF ceramic decoupling capacitor close to the VM pin plus bulk capacitance (100 uF) near the connector to absorb PWM ripple currents. Keep the BEMF sense routing (SENA/SENB/SENC) away from the high-current phase traces to avoid noise coupling into the rotor position estimator.
Configure I2C EEPROM motor parameters (phase resistance, inductance, BEMF constant) to match the exact motor; wrong parameters cause startup stalls or lock faults. Use TI TIDA-01373 programming tool reference design for parameter flashing. Also account for sleep vs standby variants (DRV10983Q vs DRV10983SQ) quiescent behavior in system power budgets.
