Product details
Overview
DRV10963JJDSNR from Texas Instruments is a three-phase, sensorless BLDC motor driver IC with integrated power MOSFETs, designed for ultra-quiet CPU cooling fans. It operates from 2.1–5.5 V, delivers up to 500 mA output current, features 180° sinusoidal control, and includes intelligent lock detection and anti-voltage surge (AVS) protection - all in a thermally enhanced 10-pin USON (3.0 mm × 3.0 mm) package.
For engineers reviewing the DRV10963JJDSNR datasheet, DRV10963JJDSNR pinout, DRV10963JJDSNR application, or DRV10963JJDSNR equivalent, key selection considerations include its 15 µA sleep-mode quiescent current, configurable FG feedback resolution (1×/2×/3× electrical cycles), OTP-programmable spin-up parameters (HOffth, TAlign, RAcc), and integrated short-circuit and thermal shutdown protection.
Technical Context
The DRV10963JJDSNR implements a proprietary sensorless, window-less 180° sinusoidal commutation scheme that eliminates torque ripple-induced acoustic noise. Its closed-loop operation relies on back-EMF zero-crossing detection without Hall sensors or external position feedback.
It integrates six N-channel power MOSFETs (total H+L RDS(on) < 1.5 Ω), programmable soft current limiting (ILIMIT = 125–875 mA), and five independent lock-detection mechanisms - including frequency overflow, BEMF abnormality, speed abnormality, open-loop stuck, and closed-loop stuck - enabling robust stall recovery in fan applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.1 V to 5.5 V - supports direct USB 5 V or low-voltage battery-powered fan systems without LDO pre-regulation. |
| Output Current | 500 mA continuous - sufficient for high-speed notebook and game console CPU cooling fans (up to ~4 W mechanical output). |
| Quiescent Current | 15 µA typical in sleep mode - enables always-on thermal management with negligible standby power draw. |
| Total RDS(on) | <1.5 Ω (H+L per phase) - minimizes conduction loss and self-heating at full load, critical for compact USON thermal performance. |
| PWM Input Frequency | 15 kHz to 100 kHz - compatible with standard microcontroller PWM peripherals and avoids audible switching noise. |
| FG Output Resolution | Configurable 1×, 2×, or 3× electrical cycle toggling - enables precise RPM calculation across diverse pole-pair motors (e.g., 2-pole to 12-pole). |
| Thermal Shutdown | 160 °C with 10 °C hysteresis - protects against sustained overload or poor heatsinking in sealed fan assemblies. |
Pinout & Package
DRV10963JJDSNR is housed in a 10-pin USON (Ultra-Thin Small Outline No-lead) package measuring 3.00 mm × 3.00 mm with an exposed thermal pad on the bottom for PCB-level heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FG) | Open-drain speed indicator output | Provides motor RPM feedback; requires external pull-up; short-circuit protected (ISC_FG = 13–25 mA). |
| 2 (FGS) | FG resolution selector input | Latched at power-up; selects FG toggle rate (1×/2×/3× electrical cycles); not dynamically changeable. |
| 3 (VCC) | Power supply input | Supplies both logic and gate-drive circuitry; UVLO thresholds at 2.1 V (rising) / 1.8 V (falling) with 200 mV hysteresis. |
| 4 (W) | Motor phase W output | High-side/low-side driven terminal for 3-phase BLDC winding; rated for –1 V to 7.7 V transient. |
| 5 (GND) | Ground reference | Primary analog/digital ground; connects to thermal pad for optimal thermal resistance (RθJB = 15.8 °C/W). |
| 6 (V) | Motor phase V output | Second motor phase terminal; shares same RDS(on) and protection features as U and W. |
| 7 (U) | Motor phase U output | Third motor phase terminal; forms complete 3-phase bridge with V and W; supports bidirectional commutation. |
| 8 (FR) | Forward/reverse direction control | Logic-level input (VIH = 2.3 V, VIL = 0.8 V); dynamically switchable to reverse commutation sequence (U→W→V). |
| 9 (GND) | Secondary ground terminal | Dedicated ground return path; improves noise immunity and current sharing between power and signal grounds. |
| 10 (PWM) | Speed command input | 9-bit resolution (0.2% step); 100% duty → full VCC phase amplitude; <1.5% duty triggers sleep mode. |
Key Features
| Feature | Design Value |
|---|---|
| Sensorless 180° Sinusoidal Control | Eliminates torque ripple and acoustic noise in fan applications without requiring Hall sensors or rotor position feedback. |
| Intelligent Lock Detection | Five independent schemes (frequency overflow, BEMF abnormal, speed abnormal, open/closed-loop stuck) enable reliable stall recovery and motor protection. |
| Anti-Voltage Surge (AVS) | Prevents VCC rail overvoltage during deceleration or tri-state events by redirecting inductive/mechanical energy to GND instead of VCC. |
| OTP-Programmable Startup | Configurable handoff threshold (HOffth), alignment time (TAlign), accelerate rate (RAcc), and minimum PWM duty cycle via one-time programmable memory. |
| Integrated Protection Suite | Includes UVLO, thermal shutdown (160 °C), short-circuit current limit (1.8 A), and soft current limit (125–875 mA) - no external components required. |
Applications
| Notebook CPU Fan Control | Game Console Cooling System |

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 |
|---|---|---|---|
| DRV10970JJDSNR | Higher 1.2 A output current; wider 4.5–24 V input range; same USON-10 package and pinout. | Targeted at larger 12 V fans (e.g., server chassis fans); not drop-in for 5 V-only designs due to higher VCC min. | Select when >500 mA drive or >5.5 V supply is required; retains identical FG/FR/PWM interface and OTP programming flow. |
| MP6532DJ-LF-Z | 2.5 A output; 4.5–28 V input; integrated current sense; different pinout (16-pin QFN); no OTP configuration. | Suited for higher-power industrial blowers; requires external current-sense resistor and layout redesign. | Choose for applications needing real-time current monitoring or >1 W mechanical output; not pin-compatible with DRV10963JJDSNR. |
Compared with DRV10963JJDSNR, DRV10970JJDSNR offers higher drive capability in identical packaging but requires ≥4.5 V supply, while MP6532DJ-LF-Z provides greater current and sensing flexibility at the cost of board redesign and loss of OTP-based startup tuning.

FAQ
What is the recommended minimum PCB copper area under the thermal pad of DRV10963JJDSNR?
TI recommends a minimum 25 mm² (5 mm × 5 mm) exposed copper area connected to a solid internal ground plane beneath the DRV10963JJDSNR thermal pad. This achieves the specified RθJB of 15.8 °C/W and prevents junction temperature exceedance at 500 mA load. The DRV10963JJDSNR datasheet Figure 10 provides exact solder mask and stencil guidelines for optimal thermal transfer.
Can the FG output of DRV10963JJDSNR drive an optocoupler directly?
No - the DRV10963JJDSNR FG pin is an open-drain output rated for 5 mA sink current at 0.3 V. Driving a typical optocoupler LED (requiring ≥5 mA at ≥1.2 V forward voltage) would violate its absolute maximum rating. A buffer transistor or dedicated level-shifter IC is required. The DRV10963JJDSNR FG output is intended for direct MCU GPIO input with external pull-up to VCC.
Does DRV10963JJDSNR support dynamic direction reversal during motor rotation?
Yes - the FR pin accepts logic-level inputs (VIH ≥ 2.3 V, VIL ≤ 0.8 V) and can be toggled at any time during operation to reverse commutation sequence (U→V→W ↔ U→W→V). The DRV10963JJDSNR handles transition safely via controlled deceleration and re-alignment; no external braking or timing coordination is needed.
How is the soft current limit (ILIMIT) configured on DRV10963JJDSNR?
The soft current limit is set via OTP bits ILIMIT[2:0] during factory programming - it cannot be changed in-system. Valid settings range from 0 (no limit) to 7 (875 mA), with DRV10963JJDSNR defaulting to 4 (500 mA). This value determines the peak phase voltage limit using Equation 5 (ULIMIT = ILIMIT × Rm + Speed × Kt) to prevent overcurrent without hard shutdown.
Is DRV10963JJDSNR qualified for automotive applications?
No - DRV10963JJDSNR is specified for commercial/industrial temperature range (–40 °C to +125 °C junction) and lacks AEC-Q100 qualification, automotive-grade screening, or extended lifetime validation. For automotive cabin fans or HVAC blower modules, TI recommends the AEC-Q100 qualified DRV10983Q or DRV10987Q instead of DRV10963JJDSNR.
