Product details
Overview
DRV10963JMDSNR 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 DRV10963JMDSNR datasheet, DRV10963JMDSNR pinout, DRV10963JMDSNR application, or DRV10963JMDSNR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative options, and supply-ready availability details - all specific to the USON-10 package variant DRV10963JMDSNR.
Technical Context
The DRV10963JMDSNR implements a proprietary sensorless, window-less 180° sinusoidal commutation scheme that minimizes torque ripple and 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 with total H+L RDS(on) < 1.5 Ω, supports dynamic direction reversal via FR pin, and uses PWM duty cycle (15–100 kHz) to scale phase voltage amplitude linearly per Vphpk = PWMdc × VCC. Lock detection employs five independent schemes including BEMF abnormality, frequency overflow, and open-loop stuck detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.1 V to 5.5 V - Enables direct integration with 3.3 V or 5 V system rails without LDO overhead. |
| Output Current | 500 mA - Sufficient for low-power cooling fans (e.g., notebook CPU fans ≤2 W). |
| RDS(on) (H+L) | <1.5 Ω - Limits conduction loss to <375 mW at 500 mA, reducing thermal load in compact USON package. |
| Quiescent Current | 15 µA (typ.) in sleep mode - Extends battery life in portable systems during idle periods. |
| PWM Frequency Range | 15 kHz to 100 kHz - Places switching energy above audible range while allowing robust filtering with small external caps. |
| FG Output Type | Open-drain speed indicator - Configurable to toggle per 1/2/3 electrical cycles for flexible RPM calculation with known pole pairs. |
| Thermal Resistance | RθJA = 40.9 °C/W - Requires minimal PCB copper area (exposed thermal pad to GND) for reliable operation at 125°C junction. |
Pinout & Package
DRV10963JMDSNR is housed in a thermally enhanced 10-pin USON (3.00 mm × 3.00 mm) package with an exposed thermal pad soldered to PCB ground for optimal 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 = 25 mA max). |
| 2 (FGS) | Speed indicator selector input | Latched at power-up; selects FG toggle rate (1×, 2×, or 3× electrical cycles) - not dynamically changeable. |
| 3 (VCC) | Power supply input | Supplies both logic and motor 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 connection; integrated MOSFET pair with RDS(on) <1.5 Ω total. |
| 5 (GND) | Ground reference | Primary analog/digital ground; connects to thermal pad for thermal performance and EMI control. |
| 6 (V) | Motor phase V output | Matches W and U in drive capability and protection; shares same RDS(on) and current limit behavior. |
| 7 (U) | Motor phase U output | Third phase terminal; commutated in sinusoidal sequence (U→V→W or U→W→V based on FR pin state). |
| 8 (FR) | Forward/reverse direction control | Logic-level input (VIH = 2.3 V); dynamically switchable to reverse commutation order without restart. |
| 9 (GND) | Secondary ground terminal | Reduces ground loop impedance; must be connected to same net as Pin 5 and thermal pad. |
| 10 (PWM) | Speed command input | Accepts 15–100 kHz PWM; 9-bit resolution (0.2% step); enters sleep mode if duty <1.5% for >500 µs. |
Key Features
| Feature | Design Value |
|---|---|
| Sensorless 180° sinusoidal control | Eliminates need for Hall sensors or external rotor position feedback, reducing BOM count and board space in fan modules. |
| Intelligent multi-scheme lock detection | Five independent lock triggers (e.g., BEMF abnormality, frequency overflow, open-loop stuck) enable robust stall recovery without external monitoring. |
| Anti-Voltage Surge (AVS) protection | Prevents VCC rail overvoltage during deceleration or tri-state events by redirecting inductive/mechanical energy to GND instead of VCC. |
| Configurable soft current limit | OTP-settable ILIMIT (0–875 mA in 125 mA steps) limits phase current during acceleration without hard shutdown or fault flag. |
| Thermally optimized USON-10 package | 3 mm × 3 mm footprint with exposed thermal pad achieves RθJB = 15.8 °C/W - enables high-power-density fan driver designs. |

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 |
|---|---|---|---|
| DRV10970MDSNR | Higher 1-A output current rating; identical USON-10 package and pinout; adds programmable slew rate control. | Required for fans drawing >500 mA (e.g., larger server chassis fans); same PCB layout but higher thermal margin needed. | Select when motor peak current exceeds 500 mA or when adjustable dv/dt is needed to reduce EMI. |
| MP6532DJ-LF-Z | Monolithic 3-phase driver with 600-mA rating; different pinout (16-pin QFN); no integrated OTP-configurable lock detection schemes. | Used in cost-sensitive consumer electronics; lacks FG/FGS configurability and AVS protection - requires external circuitry for surge handling. | Choose only if pin compatibility is not required and system-level protection can be implemented externally. |
Compared with DRV10963JMDSNR, DRV10970MDSNR offers higher current headroom in identical packaging, while MP6532DJ-LF-Z trades integrated protection and configurability for lower unit cost and broader vendor availability - neither is pin-compatible, but both serve overlapping low-power BLDC fan use cases.

FAQ
What is the maximum motor voltage supported by the DRV10963JMDSNR?
The DRV10963JMDSNR supports motor phase voltages up to 7 V (absolute maximum rating), with recommended operating range of –0.1 V to 7 V on U/V/W pins. This allows safe operation with 5 V supply and typical BEMF overshoot during transients, but does not support direct 12 V motor drive - external level-shifting or higher-voltage drivers are required for 12 V fans.
How does the DRV10963JMDSNR implement sensorless commutation without Hall sensors?
The DRV10963JMDSNR uses back-EMF zero-crossing detection during open-loop acceleration and closed-loop operation. It monitors induced voltage across unpowered phases to estimate rotor position, enabling precise 180° sinusoidal commutation. No external sensors or resistive networks are needed - all sensing and timing logic is embedded in the IC's analog front-end and control state machine.
Can the FG output frequency of the DRV10963JMDSNR be used to calculate exact motor RPM?
Yes - the FG pin toggles per 1, 2, or 3 electrical cycles depending on FGS and OTP setting FGOPT. With known motor pole-pair count (PP), RPM = (FREQFG × 60 × N) / PP, where N = 1, 2, or 3. For example, a 4-pole (2 PP) motor with FG toggling once per electrical cycle at 1 kHz yields RPM = (1000 × 60 × 1) / 2 = 30,000 RPM. The DRV10963JMDSNR datasheet provides full equations for all configurations.
Does the DRV10963JMDSNR require external current-sense resistors for protection?
No - the DRV10963JMDSNR implements both soft current limiting and short-circuit protection without external sense resistors. Soft limiting uses measured motor resistance (Rm) and Kt to estimate phase current and cap applied voltage; short-circuit protection triggers on internal voltage threshold violation. Only the DRV10963JMDSNR's integrated MOSFETs and internal analog comparators are involved.
What thermal design considerations apply to the DRV10963JMDSNR's USON-10 package?
The DRV10963JMDSNR's USON-10 package requires the exposed thermal pad to be soldered to a solid GND plane with ≥4 thermal vias (0.3 mm diameter) connecting to inner/ground layers. TI specifies RθJA = 40.9 °C/W with 1-in² 2-oz copper; insufficient copper area raises junction temperature beyond 125°C under 500 mA load. Avoid floating or undersized pads - thermal performance degrades sharply without proper pad-to-plane connection.
