Product details
Overview
DRV10963PDSNT from Texas Instruments is a three-phase, sensorless BLDC motor driver IC with integrated power MOSFETs, designed for ultra-quiet CPU fan applications. It operates from 2.1 V to 5.5 V, delivers up to 500 mA output current, features 180° sinusoidal control, and includes intelligent lock detection and anti-voltage surge (AVS) protection.
For engineers reviewing the DRV10963PDSNT datasheet, DRV10963PDSNT pinout, DRV10963PDSNT application, or DRV10963PDSNT equivalent, key selection considerations include its USON-10 package thermal performance, FG/FGS speed feedback configuration options, PWM-based amplitude-controlled sinusoidal drive, and OTP-configurable spin-up parameters for reliable fan startup under varying inertia and load conditions.
Technical Context
The DRV10963PDSNT implements a proprietary sensorless, window-less 180° sinusoidal commutation algorithm that eliminates torque ripple and enables silent operation. Its closed-loop control uses back-EMF zero-crossing detection without Hall sensors or external position feedback.
It integrates six N-channel power MOSFETs with total H+L RDS(on) < 1.5 Ω, supports dynamic direction reversal via FR pin, and provides configurable lock detection using five independent schemes-including frequency overflow, BEMF abnormality, and open-loop stuck detection-each with defined timing thresholds (e.g., TON_LOCK = 0.3 s).
Key Specifications

|---|---|
| Supply Voltage Range | 2.1 V to 5.5 V - Enables direct compatibility with 3.3 V and 5 V system rails without LDO overhead. |
| Output Current Rating | 500 mA - Sufficient for driving small-form-factor notebook and game station CPU cooling fans. |
| Total RDS(on) | <1.5 Ω (H+L) - Minimizes conduction loss and self-heating in thermally constrained fan modules. |
| Sleep Quiescent Current | 15 µA typical - Extends battery life in portable systems during fan idle periods. |
| PWM Input Frequency | 15 kHz to 100 kHz - Supports high-resolution speed control while avoiding audible noise bands. |
| Thermal Resistance (RθJA) | 40.9 °C/W - Validated for 3 mm × 3 mm USON package with exposed thermal pad soldered to PCB ground plane. |
| Lock Detection Time | 0.3 s (TON_LOCK) - Fast stall response prevents motor overheating and MOSFET thermal runaway. |
Pinout & Package
DRV10963PDSNT is housed in a 3.00 mm × 3.00 mm, 10-pin USON (Ultra Thin Small Outline No-lead) package with an exposed thermal pad on the bottom surface, requiring connection to PCB ground for optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FG) | Open-drain speed indicator output | Provides motor RPM feedback; toggles once per 1–3 electrical cycles depending on FGS/FGOPT OTP settings. |
| 2 (FGS) | Speed indicator selector input | Latched at power-up; selects FG toggle frequency (1×, 2×, or 3× electrical cycle) for accurate mechanical speed calculation. |
| 3 (VCC) | Power supply input | Supplies both logic and motor drive circuitry; accepts 2.1–5.5 V with UVLO hysteresis of 200 mV. |
| 4 (W) | Motor phase W output | High-side/low-side driven terminal for three-phase BLDC winding; part of integrated half-bridge stage. |
| 5 (GND) | Ground reference | Primary signal and power return; two dedicated GND pins (pins 5 and 9) reduce ground impedance and improve EMI immunity. |
| 6 (V) | Motor phase V output | Second motor phase terminal; shares same RDS(on) and protection features as U and W outputs. |
| 7 (U) | Motor phase U output | Third motor phase terminal; enables full sinusoidal commutation sequence (U→V→W or U→W→V). |
| 8 (FR) | Direction control input | Logic-level pin (VIH = 2.3 V) enabling real-time forward/reverse commutation switching without reset. |
| 9 (GND) | Ground reference | Secondary ground connection; must be tied to same net as pin 5 and thermal pad for low-impedance return path. |
| 10 (PWM) | Speed command input | Accepts 15–100 kHz PWM signal; duty cycle maps linearly to output voltage amplitude (Vphpk = PWMdc × VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Proprietary sensorless 180° sinusoidal control | Eliminates audible commutation noise and torque ripple in fan applications without external sensors or complex tuning. |
| Configurable minimum PWM duty cycle (OTP) | Supports 0%, 5%, 10%, or 13% lower limit to prevent unintended low-speed operation or stalling during startup. |
| Five-lock-detection schemes | Detects stalled rotor under diverse failure modes (e.g., BEMF abnormality, frequency overflow, open-loop stuck) with autonomous recovery. |
| Anti-Voltage Surge (AVS) protection | Prevents VCC rail overvoltage during deceleration or tri-state events by redirecting inductive/mechanical energy to ground instead of the supply. |
| Soft current limiting (OTP-configurable) | Adjustable 0–875 mA limit using motor resistance (Rm) and Kt to avoid hard current cutoff and maintain smooth acceleration. |
| OTP-programmable spin-up profile | Enables optimization of align time (40–600 ms), accelerate rate (10–150 Hz/s), and handoff threshold (12.5–187.5 Hz) for motor-specific reliability. |

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 |
|---|---|---|---|
| DRV10970PDSNR | Higher 1-A output current rating; wider 4.5–24-V input range; same USON-10 package but larger 4-mm × 4-mm footprint. | Targeted at higher-power 12-V fans (e.g., server chassis); not drop-in compatible due to different VCC range and pinout mapping. | Select DRV10970PDSNR only when >500 mA drive capability and 12-V operation are required; revalidation of layout and startup timing needed. |
| MP6532DQFU-LF-Z | Monolithic 3-phase driver with 600-mA rating; 2.5–18-V input; lacks OTP configurability and multi-scheme lock detection. | Used in cost-sensitive consumer electronics; relies on simpler single-threshold lock detection and fixed startup profile. | Choose MP6532DQFU-LF-Z for basic fan control where programmability and advanced stall recovery are unnecessary; verify FG feedback compatibility. |
Compared with DRV10963PDSNT, DRV10970PDSNR offers higher voltage/current headroom at the expense of pinout and thermal pad redesign, while MP6532DQFU-LF-Z trades configurability and fault resilience for lower BOM cost and simpler integration in non-critical applications.

FAQ
What is the recommended PCB layout practice for thermal management of the DRV10963PDSNT?
The DRV10963PDSNT requires the exposed thermal pad on the bottom of its USON-10 package to be soldered to a solid copper ground plane with ≥4 thermal vias (0.3 mm diameter) connecting to inner/secondary ground layers. This achieves the specified RθJA of 40.9 °C/W. Avoid splitting the thermal pad net or routing signals underneath it; keep high-current motor traces (U/V/W) short and symmetric to minimize loop inductance and EMI.
How does the DRV10963PDSNT determine motor speed without Hall sensors or encoders?
The DRV10963PDSNT uses sensorless back-EMF zero-crossing detection during closed-loop operation to estimate rotor position and speed. It measures induced voltage across unpowered phases to detect commutation points, then calculates electrical frequency. The FG pin outputs a pulse train whose frequency corresponds to motor speed-configurable to toggle once per 1, 2, or 3 electrical cycles via FGS/FGOPT settings for precise mechanical RPM derivation.
Can the DRV10963PDSNT drive motors with different pole pair counts?
Yes, the DRV10963PDSNT supports motors with any number of pole pairs. Mechanical RPM is calculated from FG frequency using formulas that incorporate pole pair count: RPM = (FREQFG × 60)/Np (if FGS = 1), or scaled by 2× or 3× depending on FGOPT/FGS configuration. The internal control loop adapts automatically-the only design impact is correct selection of handoff threshold (HOffth) and Kt calibration during OTP programming.
What protection features does the DRV10963PDSNT include to prevent damage during abnormal operation?
The DRV10963PDSNT integrates five lock detection schemes, short-circuit current protection (1.8 A trip), thermal shutdown (160°C with 10°C hysteresis), UVLO (2.1 V turn-on, 1.8 V turn-off), anti-voltage surge (AVS) to clamp VCC during deceleration, and soft current limiting (configurable 0–875 mA). These operate autonomously without MCU supervision, placing phases in high-impedance state and restarting after TOFF_LOCK (5 s) upon fault clearance.
Is the DRV10963PDSNT pin-compatible with other devices in the DRV109xx family?
No, the DRV10963PDSNT is not pin-compatible with other DRV109xx variants. While it shares the USON-10 package outline with DRV10970PDSNR, pin functions differ-for example, DRV10970PDSNR repurposes pin 2 for VREF and moves FGS functionality elsewhere. The DRV10963PDSNT pinout (FG/FGS/VCC/W/GND/V/U/FR/GND/PWM) is unique to this variant and must be implemented per its specific schematic and layout guidelines.
