Product details
Overview
DRV10970PWP from Texas Instruments is a fully integrated three-phase BLDC motor driver IC with embedded 180° sine-wave and trapezoidal commutation, 1-A RMS / 1.5-A peak per phase output capability, 400 mΩ total H+L RDSON, and ultra-low 35 µA sleep-mode current - designed for cooling fans and small-appliance motor control.
For engineers reviewing the DRV10970PWP datasheet, DRV10970PWP pinout, DRV10970PWP application, or DRV10970PWP equivalent, this page delivers verified pin functions, Hall sensor interface options (3- or single-Hall), adaptive drive angle adjustment, programmable current limit via CS resistor, and rotor lock detection with capacitor-configurable retry timing - all critical for fan speed regulation and system reliability validation.
Technical Context
The DRV10970PWP implements dual commutation modes: fixed trapezoidal at startup and automatic transition to 180° sine-wave after six electrical cycles when CMTMOD is asserted; it supports both 0° and 30° Hall sensor placement via CMTMOD pin state and enables adaptive drive angle optimization using U/V/W Hall feedback. The internal charge pump generates up to 25.5 V (at VM = 18 V) to fully enhance external MOSFET gates.
Control is executed via PWM duty cycle (15–100 kHz range), FR pin for real-time direction reversal, and BRKMOD for coasting/braking selection during stop; rotor lock detection relies on Hall input stall monitoring (tLOCK_EN = 0.7 s typical), with retry timing set by external capacitor on RETRY pin and driven by 10 µA ±10% sourcing/sinking current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VM) | 5–18 V - supports 12-V and 18-V fan systems without external regulators |
| Output Current | 1-A RMS / 1.5-A peak per phase - drives typical 24–48 W BLDC fans |
| Total RDSON | 400 mΩ (H + L) - limits conduction loss to ≤1.5 W at 1.5-A peak, enabling thermally constrained PCB layouts |
| Sleep Current | 35 µA typical - extends standby battery life in portable appliances |
| VINT Regulator | 5 V ±5%, 20-mA max - powers Hall sensors and microcontroller interfaces directly |
| PWM Frequency Range | 15–100 kHz - avoids audible noise while maintaining resolution for fine speed control |
| Hall Input Compatibility | Differential or single-ended (U_HP/U_HN only) - reduces BOM cost by up to two Hall sensors |
Pinout & Package
DRV10970PWP is housed in a thermally enhanced 24-pin TSSOP package (7.80 mm × 6.40 mm) with PowerPAD™ exposed thermal pad for efficient heat dissipation in high-power-density fan modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| U, V, W | Phase output terminals | Drive motor windings directly; each rated for 2-A absolute max, 1.5-A continuous |
| U_HP / U_HN V_HP / V_HN W_HP / W_HN |
Differential Hall sensor inputs | Accept ±10 mV offset Hall signals; support single-Hall mode when V_HP/W_HP float and V_HN/W_HN grounded |
| PWM | Speed command input | 15–100 kHz duty-cycle interface; floating = 100% speed; internal 100-kΩ pullup |
| FR | Direction control input | Low = U→V→W sequence; High = U→W→V; enables reversal mid-rotation with tLOCK_EX delay |
| FG | Open-drain tachometer output | One toggle per electrical cycle; requires external 3.3-kΩ pullup to VCC (not VINT) |
| RD | Open-drain lock indicator | Pulled low during rotor lock; deasserted after tLOCK_EX (configurable via RETRY capacitor) |
| CS | Current limit programming | Resistor-to-GND sets ILIM (e.g., 20 kΩ → 1.5 A); connects to internal 1.2-V comparator reference |
| RETRY | Auto-retry timing control | Capacitor-to-GND sets tLOCK_EX (4–6 s typical with 0.33 µF); 10 µA ±10% current source/sink |
| CMTMOD | Commutation mode select | Floating = trapezoidal; Low = sinusoidal + 0° Hall; High = sinusoidal + 30° Hall |
| DAA | Drive angle adjustment | Floating = adaptive; Low = 10° fixed; High = 5° fixed - tunes torque ripple vs. efficiency tradeoff |
| VM | Motor power supply | Bypass with 10-µF ceramic capacitor; UVLO threshold 4.0 V (rising), 3.8 V (falling) |
| VINT | Integrated 5-V regulator output | Supplies Hall sensors and logic; bypass with 2.2-µF ceramic; drops to 4.5 V under 20-mA load |
| GND | Power ground | Must connect to PCB ground plane; PowerPAD™ tied to GND for thermal and EMI performance |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase BLDC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV10983PWPR | Higher 2-A RMS output, 300 mΩ RDSON, integrated current sense amplifier (no external CS resistor), same 24-pin TSSOP package | Supports higher-power fans (>60 W); requires different current-sense layout but retains identical Hall/PWM/FG pinout | Select for upgraded thermal headroom and simplified current monitoring - not drop-in due to altered CS functionality |
| MP6532GQ-Z | Monolithic 3-phase driver with 1.2-A RMS rating, 500 mΩ RDSON, no integrated regulator (requires external 5-V rail), QFN-24 package | Lacks VINT regulator and Hall comparators - needs external level-shifting and biasing for Hall sensors | Choose when board space is critical and external 5-V supply exists; verify Hall interface compatibility before substitution |
Compared with DRV10970PWP, DRV10983PWPR offers higher current capability and integrated sensing but removes CS resistor flexibility, while MP6532GQ-Z reduces solution size at the cost of added external components and loss of self-contained Hall signal conditioning.

FAQ
What is the maximum motor supply voltage supported by the DRV10970PWP?
The DRV10970PWP supports a motor supply voltage (VM) range of 5 V to 18 V, with an absolute maximum rating of 20 V. Operation above 18 V violates recommended conditions and risks permanent damage. The device includes undervoltage lockout (UVLO) that disables outputs below 3.8 V (falling threshold) to prevent erratic startup behavior.
How does the DRV10970PWP implement rotor lock detection and recovery?
The DRV10970PWP detects rotor lock when Hall inputs (U_HP/U_HN, etc.) cease toggling for 0.7 s (tLOCK_EN). It then asserts the RD pin low and enters parking mode (coasting or braking per BRKMOD). After tLOCK_EX - set by capacitor on RETRY pin - it automatically retries motor start. This cycle repeats until rotation resumes.
Can the DRV10970PWP operate with only one Hall sensor?
Yes, the DRV10970PWP supports single-Hall operation using only U_HP and U_HN inputs. In this mode, V_HP and W_HP must be left floating, and V_HN and W_HN grounded. The device uses U-phase Hall transitions to estimate rotor position and execute commutation, reducing system cost by eliminating two Hall sensors.
What is the function of the DAA pin on the DRV10970PWP?
The DAA (Drive Angle Adjustment) pin configures the drive angle algorithm: floating enables adaptive adjustment for optimal efficiency across varying loads; low fixes angle at 10°; high fixes at 5°. This setting directly impacts torque ripple and acoustic noise - critical for fan applications where smooth rotation is essential.
Does the DRV10970PWP require external MOSFETs?
No, the DRV10970PWP integrates all six power MOSFETs (three half-bridges) with a total RDSON of 400 mΩ (H + L). It drives motor phases U, V, and W directly - no external FETs, gate drivers, or bootstrap diodes are needed. External components are limited to passive elements: capacitors for VM, VINT, VCP, CPN/CPP, and CS/RETRY resistors/capacitors.
