Product details
Overview
DRV8412DDW from Texas Instruments is a dual full-bridge PWM motor driver IC designed for brushed DC and stepper motor control in industrial and robotic systems. It delivers up to 2 × 3A continuous output current (2 × 6A peak) in dual full-bridge mode, features 110mΩ RDS(on) MOSFETs at TJ = 25°C, supports up to 52V supply voltage, and operates at PWM frequencies up to 500kHz - enabling high-efficiency (up to 97%) motion control in compact thermal designs.
For engineers reviewing the DRV8412DDW datasheet, DRV8412DDW pinout, DRV8412DDW application, or DRV8412DDW equivalent, key selection considerations include its HTSSOP-44 (DDW) package with independent PVDD/GND per half-bridge, programmable cycle-by-cycle current limiting via OC_ADJ, integrated overtemperature/overcurrent/undervoltage protection, and support for parallel full-bridge (PFB) and dual full-bridge (DFB) configurations using M1–M3 mode pins.
Technical Context
The DRV8412DDW integrates four independently controlled half-bridges (A–D) with dedicated PVDD, GND, and GVDD pins per bridge, enabling precise current sensing via external shunt resistors and operation with mixed-voltage motor loads. Its intelligent gate drive includes cross-conduction prevention and bootstrap capacitor recharge sequences to maintain high-side FET bias under low-duty or low-frequency PWM conditions.
Protection architecture implements two-stage thermal response (OTW warning at 125°C, OTSD shutdown at 150°C), fast 250ns overcurrent detection with resistor-programmable threshold (9.7A typical with 27kΩ), and bootstrap undervoltage recovery - all while maintaining Hi-Z fault response and open-drain FAULT/OTW signaling compatible with 3.3V or 5V logic via internal VREG pullups.

Pinout & Package
The DRV8412DDW is housed in a thermally enhanced HTSSOP-44 (DDW) package measuring 14 mm × 8.1 mm with exposed power pad for PCB thermal sinking. The package includes 44 leads and requires soldering of the thermal pad to a GND-connected landing pad with vias for optimal junction-to-board thermal resistance (RθJB = 5.5°C/W).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual full-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8432DKD | Higher 2 × 7A continuous output; HSSOP-36 package; different pinout and thermal pad layout | Targeted at higher-power motors requiring >3A per bridge; not pin-compatible with DRV8412DDW | Select when system demands >6A continuous drive and can accommodate larger footprint and revised layout |
| TB9051FTG | Automotive-grade dual H-bridge; 3.5A continuous; built-in SPI interface and diagnostics; 5V logic supply only | Designed for ASIL-B automotive body control; lacks OC_ADJ programmability and independent PVDD per bridge | Choose for automotive environments requiring functional safety compliance and serial configurability over analog tuning |
Compared with DRV8432DKD, the DRV8412DDW offers lower thermal density in a smaller 14×8.1mm footprint but trades off peak current capability; versus TB9051FTG, it provides greater analog flexibility and industrial voltage range at the cost of automotive qualification and embedded diagnostics.

FAQ
What is the maximum continuous output current rating for DRV8412DDW in dual full-bridge mode?
The DRV8412DDW supports up to 2 × 3A continuous output current (6A total) in dual full-bridge mode, with 2 × 6A peak capability. This rating assumes proper PCB thermal design including soldering of the exposed power pad to a GND plane with thermal vias, ambient temperature ≤85°C, and adequate airflow or heatsinking. Derating applies above 70°C ambient - at 85°C, continuous output drops to 2.6A per bridge per TI's DDW package power derating curve.
How does the OC_ADJ pin on DRV8412DDW configure overcurrent protection?
The OC_ADJ pin on DRV8412DDW sets the overcurrent trip threshold by connecting an external resistor to AGND. Using a 27kΩ resistor yields a nominal 9.7A trip point; values from 22kΩ (11.6A) to 36kΩ (7.4A) are supported. This resistor programs both cycle-by-cycle current limiting and latching shutdown thresholds. The DRV8412DDW datasheet Table 6-2 specifies exact correlations, and device-to-device variation of ±20% must be accounted for in safety-critical designs.
Can DRV8412DDW operate in parallel full-bridge (PFB) mode, and what are the requirements?
Yes, DRV8412DDW supports parallel full-bridge mode delivering 6A continuous (12A peak) by configuring M1=0, M2=1, M3=0. In this mode, OUT_A/OUT_B and OUT_C/OUT_D are internally paralleled to form two high-current outputs. PVDD_A/PVDD_B and PVDD_C/PVDD_D must be shorted respectively, and GND_A/GND_B and GND_C/GND_D tied together. External current-sharing inductors are not required due to matched RDS(on), but thermal management becomes critical - power dissipation doubles compared to dual-bridge mode.
What thermal management practices are recommended for DRV8412DDW in high-current operation?
For DRV8412DDW operating near its 3A-per-bridge limit, TI recommends soldering the exposed thermal pad to a minimum 34mm² copper area on the PCB's inner or bottom layer, connected via ≥6 thermal vias (0.3mm diameter) to internal GND planes. With this layout, RθJA is 24.5°C/W; adding a heatsink reduces it to ~13°C/W. Ambient temperature must stay ≤85°C, and power dissipation should be limited to 3.2W at 70°C ambient per the DDW package derating table - exceeding this risks OTSD activation.
Does DRV8412DDW require external Schottky diodes or snubbers for flyback energy handling?
No, DRV8412DDW does not require external Schottky diodes or RC snubbers. Its integrated MOSFETs feature intrinsic body diodes with 1V forward drop (TJ = 25–125°C, IO = 5A) and intelligent gate drive actively manages shoot-through prevention and dead time (5.5ns typical). The device's internal protection circuits - including overcurrent detection and bootstrap recharge - handle inductive kickback safely across its full 500kHz PWM range without added components.
