Product details
Overview
DRV8332HDDV from Texas Instruments is a high-efficiency, three-phase PWM motor driver IC designed for extreme-temperature operation (–55°C to 175°C). It integrates six N-channel MOSFETs with 260 mΩ RDS(on) (HS/LS, TJ = 25°C), supports up to 50 V PVDD, delivers 5 A continuous phase current, and operates at switching frequencies up to 500 kHz - enabling compact BLDC and PMSM motor control in aerospace, downhole, and industrial inverters.
For engineers reviewing the DRV8332HDDV datasheet, DRV8332HDDV pinout, DRV8332HDDV application, or DRV8332HDDV equivalent, key selection considerations include its independent half-bridge supply/ground architecture, programmable cycle-by-cycle overcurrent protection via OC_ADJ resistor, bootstrap-based high-side gate drive, and fault reporting via open-drain FAULT/OTW outputs with internal 3.3 V pull-ups.
Technical Context
The DRV8332HDDV implements three fully independent half-bridge power stages, each with dedicated GVDD_X, PVDD_X, GND_X, BST_X, and OUT_X pins - enabling isolated shunt-based current sensing and mixed-voltage motor phases. Its gate drive uses adaptive dead-time control (5.5 ns) and integrated bootstrap charging with undervoltage protection (BST_UVP) to sustain high-side FET conduction down to 10 kHz PWM.
Protection is implemented via parallel, per-FET current detectors with user-programmable trip thresholds (30–200 kΩ OC_ADJ resistor), dual-mode response (cycle-by-cycle limiting or latching shutdown), plus coordinated undervoltage (GVDD/VDD < 8.5 V), overtemperature (>125°C OTW warning, >175°C shutdown), and short-circuit detection - all asserting FAULT low within 250 ns of fault onset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PVDD operating range | 0–50 V DC; supports wide-input industrial and automotive battery-fed inverters without external pre-regulation |

Pinout & Package
DRV8332HDDV is housed in a thermally enhanced 44-pin HTSSOP (DDV) package with exposed thermal pad, optimized for high-power density and junction-to-board thermal resistance of 17.4°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT_A / OUT_B / OUT_C | Half-bridge output node | Drives motor phase windings directly; requires external bootstrap capacitor to BST_X for high-side FET gate bias |
| PVDD_A / PVDD_B / PVDD_C | Power-stage supply input | Independent 50 V-rated inputs per phase - enable differential bus architectures and localized decoupling |
| GVDD_A / GVDD_B / GVDD_C | Gate-drive voltage supply | 12 V logic/gate supply per half-bridge; powers level-shifted drivers and enables independent gate bias control |
| BST_A / BST_B / BST_C | Bootstrap supply terminal | Connects to external capacitor (33–220 nF) tied to corresponding OUT_X; forms floating rail for high-side gate drive |
| PWM_A / PWM_B / PWM_C | Input control signal | CMOS-compatible (0.8–3.6 V logic) inputs accepting standard 3.3 V or 5 V PWM; no external level-shifting required |
| FAULT / OTW | Open-drain fault indicators | Active-low signals with internal 3.3 V pull-up to VREG; report latched faults (FAULT) and overtemperature warning (OTW) |
| OC_ADJ | Analog current limit programming | Resistor-to-AGND sets cycle-by-cycle overcurrent threshold (e.g., 36 kΩ → 7.4 A); enables motor-specific current tuning |
| RESET_A / RESET_B / RESET_C | Independent half-bridge reset | Active-low asynchronous reset; clears cycle-by-cycle faults individually or latched faults collectively |
| GND_A / GND_B / GND_C | Phase-specific power ground | Isolated ground returns per half-bridge - essential for accurate shunt-based current measurement and noise immunity |
| AGND | Analog reference ground | Separate low-noise ground for VREG, OC_ADJ, and internal analog comparators; must be star-connected to minimize offset |
Key Features
| Feature | Design Value |
|---|---|
| Independent half-bridge supplies & grounds | Enables true three-phase current sensing using single shunt per phase and eliminates ground loop coupling between phases |
| Programmable cycle-by-cycle overcurrent limit | Adjustable trip point (1.4–8.8 A) via single external resistor - avoids motor stall damage while preserving dynamic torque response |
| Integrated bootstrap undervoltage protection (BST_UVP) | Automatically recharges bootstrap capacitors during low-duty or low-frequency PWM - prevents high-side FET dropout without external circuitry |
| 175°C junction-rated silicon + extended life qualification | Validated for 1000 hours at 175°C; meets reliability requirements for oil & gas, aerospace, and military embedded systems |
| No external snubber or Schottky diode required | Internal charge pump and optimized gate drive timing eliminate need for external recovery components - reduces BOM count and board area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8323RSRTVT | 40-V max PVDD, 3.5-A continuous, SPI interface, integrated current sense amps, -40°C to 125°C | Targeted at cost-sensitive industrial drives with digital control and onboard diagnostics - lacks extreme-temperature rating and independent GND_X pins | Select when system-level diagnostics, lower BOM count, and SPI configurability outweigh need for >125°C operation |
| MP6532GQ-Z | 60-V max PVDD, 5-A continuous, 3-phase gate driver only (no integrated FETs), -40°C to 125°C | Requires external high/low-side MOSFETs; suited for custom power stage designs needing higher voltage or thermal customization | Select when discrete FET selection (e.g., SiC/GaN), layout flexibility, or >50 V bus voltage is required |
Compared with DRV8332HDDV, DRV8323RSRTVT offers digital configurability but sacrifices extreme-temperature capability and phase-isolated grounding, while MP6532GQ-Z provides voltage scalability and layout freedom at the cost of increased component count and loss of integrated protection logic.

FAQ
What is the maximum allowable PVDD voltage for the DRV8332HDDV?
The absolute maximum PVDD voltage for DRV8332HDDV is 70 V, but the recommended operating maximum is 50 V. Exceeding 50 V risks violating the 52.5 V upper limit specified in Recommended Operating Conditions and may trigger overvoltage-related stress or premature wear, especially at elevated junction temperatures. The device is rated for continuous operation at 50 V PVDD across its full –55°C to 175°C temperature range.
How does the OC_ADJ pin configure overcurrent protection on the DRV8332HDDV?
The OC_ADJ pin on DRV8332HDDV accepts an external resistor connected to AGND to set the cycle-by-cycle overcurrent threshold. Using a 36 kΩ resistor yields a nominal 7.4 A trip point; values from 30 kΩ to 200 kΩ correspond to 8.8 A down to 1.4 A. This resistor directly programs the internal current-sense amplifier gain - not a digital register - so the setting is analog, monotonic, and functional immediately after power-up without firmware initialization.
Can the DRV8332HDDV operate without external bootstrap capacitors?
No, the DRV8332HDDV cannot operate its high-side FETs without external bootstrap capacitors. Each BST_X pin (BST_A, BST_B, BST_C) must be connected via a 33–220 nF ceramic capacitor (X5R or better) to its corresponding OUT_X pin. These capacitors provide the floating gate-drive voltage needed for high-side N-channel MOSFETs. Omitting them results in immediate high-side FET failure or non-functional PWM output, as confirmed in the Theory of Operation section of the DRV8332HDDV datasheet.
What is the purpose of the separate GND_A, GND_B, and GND_C pins on the DRV8332HDDV?
The separate GND_A, GND_B, and GND_C pins on DRV8332HDDV provide isolated power return paths for each half-bridge, enabling accurate, noise-immune current measurement using external shunt resistors placed between OUT_X and GND_X. This architecture prevents current-sensing errors caused by shared ground impedance and cross-talk between phases - a critical requirement for field-oriented control (FOC) in high-performance motor drives where torque ripple must be minimized.
Does the DRV8332HDDV include internal protection against shoot-through?
Yes, the DRV8332HDDV includes hardware-level shoot-through prevention via fixed 5.5 ns dead-time insertion between high-side and low-side FET switching transitions. This dead-time is implemented in the gate driver logic and is independent of PWM input timing - ensuring that both FETs in any half-bridge are never simultaneously conductive, even with imperfect or overlapping PWM signals. This feature is explicitly documented in the Electrical Characteristics table under parameter "tDT".
