Product details
Overview
DRV10983SQPWPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified, three-phase sensorless BLDC motor driver with integrated MOSFETs, delivering 2-A continuous winding current (3-A peak), 6.2–28-V motor operating range, and on-chip 5-V buck + 3.3-V/1.8-V LDOs - designed for ultra-quiet fan and pump control in vehicle cabin ventilation systems.
For engineers reviewing the DRV10983SQPWPRQ1 datasheet, DRV10983SQPWPRQ1 pinout, DRV10983SQPWPRQ1 application, or DRV10983SQPWPRQ1 equivalent, key selection considerations include its I²C-configurable sinusoidal 180° commutation, analog/PWM SPEED input flexibility, FG tach feedback, DIR polarity control, and integrated AVS/UVLO/thermal/lock protection without external sense resistors.
Technical Context
The DRV10983SQPWPRQ1 implements a proprietary sensorless BEMF estimation algorithm enabling continuous sinusoidal 180° phase drive - eliminating hall sensors while minimizing torque ripple and acoustic noise. Its commutation logic dynamically adapts to motor back-EMF zero-crossing timing across speed and load conditions.
It integrates a hysteretic 5-V step-down regulator (configurable as buck or linear mode), dual LDOs (3.3 V/1.8 V), and a charge-pump circuit driving internal high-side FETs. Protection includes phase-to-phase/phase-to-GND overcurrent detection, rotor lock sensing, anti-voltage surge (AVS) response to 45-V load dump, and thermal shutdown at 150–180°C with 15–25°C hysteresis.
Key Specifications

Pinout & Package
DRV10983SQPWPRQ1 is housed in a thermally enhanced HTSSOP-24 package (7.80 mm × 6.40 mm) with exposed thermal pad (GND-connected), supporting AEC-Q100 Grade 1 operation (–40°C to +125°C ambient).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCP, CPP, CPN | Charge pump network | Supports high-side gate drive; requires 0.1-µF ceramic capacitor between CPN-CPP and VCP-VCC for stable operation. |
| SW, SWGND | Buck regulator switching node | Connects to external 47-µH inductor (buck mode) or 39-Ω resistor (linear mode); SWGND must be low-inductance path to PGND. |
| VREG, V3P3, V1P8 | Regulated power outputs | VREG = 5-V buck output (100 mA); V3P3 = 3.3-V LDO (20 mA, can drive external loads); V1P8 = 1.8-V core supply (internal only). |
| U, V, W, PGND | Motor phase outputs & power ground | Three half-bridge outputs driving BLDC motor windings; PGND pins (15,16) must be tied directly to thermal pad and low-impedance ground plane. |
| SPEED, DIR, FG | Motor control interface | SPEED accepts analog (0–3.3 V) or PWM (0.1–100 kHz); DIR sets U→V→W (low) or U→W→V (high); FG outputs open-drain tach signal synchronized to commutation. |
| SCL, SDA, GND | I²C communication & reference | Standard I²C bus (3.3-V tolerant); GND (pin 8) is digital/analog reference for all logic and analog functions. |

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 | Same HTSSOP-24 package; sleep-mode version (48 µA vs 8.5 mA standby); identical motor drive specs and protection features. | Preferred where lowest quiescent current is critical (e.g., always-on battery-powered modules); lacks continuous 5-V rail for external MCU during idle. | Select DRV10987QPWPRQ1 only if system requires sub-100-µA sleep current and can tolerate regulator shutdown during idle periods. |
| MP6532GQ-Z | Monolithic 3-phase driver with 2.5-A peak; no integrated buck regulator; requires external 3.3-V supply; I²C-only interface (no analog/PWM SPEED or FG). | Suitable for space-constrained designs where external regulators already exist and tach feedback is not required; lacks automotive qualification and load dump tolerance. | Choose MP6532GQ-Z when BOM cost is prioritized over automotive compliance and integrated power management. |
Compared with DRV10983SQPWPRQ1, DRV10987QPWPRQ1 offers deeper sleep but sacrifices always-on 5-V rail functionality, while MP6532GQ-Z reduces integration level and excludes automotive-grade protections - making DRV10983SQPWPRQ1 optimal for cost-sensitive, safety-aware fan/pump systems needing self-contained power and flexible control.

FAQ
What is the difference between DRV10983SQPWPRQ1 and DRV10983Q variants?
The DRV10983SQPWPRQ1 is the standby-mode version, drawing 8.5 mA in standby while maintaining active 5-V and 3.3-V regulator outputs - ideal for systems where an external microcontroller must remain powered. In contrast, the DRV10983Q variant enters deep sleep (48 µA) and shuts down all regulators. Both share identical motor drive performance, pinout, and protection features. The DRV10983SQPWPRQ1 part number explicitly denotes the standby version in HTSSOP-24 packaging.
Does DRV10983SQPWPRQ1 require an external current-sense resistor?
No, DRV10983SQPWPRQ1 implements internal overcurrent protection without any external sense resistor. It monitors phase current using integrated MOSFET RDS(on) sensing and provides protection against phase-to-phase, phase-to-GND, and phase-to-VCC shorts. This eliminates BOM cost and layout area typically needed for shunt resistors and amplifiers - a key advantage confirmed in the device's Electrical Characteristics table (IOC_limit_HS/LS parameters).
Can DRV10983SQPWPRQ1 operate with a 5-V-only supply?
No, DRV10983SQPWPRQ1 requires a minimum 6.2-V supply to drive the motor, though its registers remain preserved down to 4.5 V. A 5-V supply is insufficient for motor operation and will result in UVLO activation (VUVLO_R = 5.8–6.2 V). However, the integrated 5-V buck regulator can *output* 5 V to external circuits when powered from a compliant 6.2–28-V source - it does not accept 5 V as input.
How is thermal management handled in DRV10983SQPWPRQ1?
DRV10983SQPWPRQ1 incorporates junction temperature monitoring with thermal shutdown at 150–180°C (hysteresis 15–25°C) and a warning threshold at 115–140°C. Its HTSSOP-24 package features an exposed thermal pad that must be soldered to a PCB ground plane with multiple vias for effective heat dissipation. Thermal metrics (RθJA = 36.1°C/W, RθJC(bot) = 1.1°C/W) confirm efficient bottom-side conduction - critical for sustaining 2-A continuous current in automotive ambient temperatures up to 125°C.
What protection features does DRV10983SQPWPRQ1 provide against automotive electrical transients?
DRV10983SQPWPRQ1 includes Anti-Voltage Surge (AVS) protection to handle load dump events up to 45 V (with slew rate <1 V/µs), undervoltage lockout (UVLO) with 6.2-V rising threshold, overcurrent protection on all phases, rotor lock detection, and thermal shutdown. These are AEC-Q100-compliant safeguards validated for automotive Grade 1 operation (–40°C to +125°C ambient), ensuring robustness against ISO 7637-2 Pulse 5a transients and battery disconnection scenarios without external TVS diodes.
