Product details

Overview

DRV8350HRTVR from Texas Instruments is a 9–100-V, three-phase smart gate driver IC for N-channel MOSFETs in BLDC motor control systems. It integrates high-side charge pump, low-side linear regulator, 50–1000-mA adjustable peak gate drive current, V_DS overcurrent protection, and hardware-only PWM interface - enabling compact, robust motor drives for e-mobility and power tools.

For engineers reviewing the DRV8350HRTVR datasheet, DRV8350HRTVR pinout, DRV8350HRTVR application, or DRV8350HRTVR equivalent, key selection factors include its 32-pin WQFN package, absence of integrated buck regulator or shunt amplifiers (per DRV8350H variant), hardware interface mode, and 9–100-V VM operating range with shoot-through prevention and dV/dt mitigation.

Technical Context

The DRV8350HRTVR implements Smart Gate Drive (SGD) architecture with V_GS handshake logic and programmable dead-time insertion to prevent shoot-through. Its charge pump supports 100% PWM duty cycle on high-side drivers, while strong pulldown circuitry suppresses parasitic dV/dt turn-on.

It operates in 6x, 3x, 1x, or independent PWM modes - with 1x mode using internal commutation table for sensored trapezoidal control. Fault handling includes VM UVLO, GDUV, OCP, thermal warning/shutdown, and open-drain nFAULT output.

Key Specifications

Parameter	Value and Actual Design Meaning
VM Supply Range	9 V to 100 V - powers gate drivers directly from battery or bus; supports wide-input e-bike, power tool, and industrial BLDC systems.
Peak Gate Drive Current	50 mA to 1 A source / 100 mA to 2 A sink - configurable via IDRIVE pin resistor to match MOSFET Q_g and switching loss requirements.
Interface Type	Hardware-only (H-mode) - uses six discrete INx/INy inputs; no SPI required; simplifies controller firmware and reduces BOM count.
Integrated Protection	VM UVLO, GDUV, V_DS OCP, shoot-through prevention, thermal warning/shutdown - enables self-protected operation without external fault monitoring circuitry.
Package	32-pin WQFN (5.0 mm × 5.0 mm, 0.5-mm pitch) with exposed thermal pad - optimized for high-power density motor drive PCB layouts.
Sleep Current	20 µA at V_VM = 48 V - enables ultra-low-power standby in battery-powered applications like e-scooters and cordless tools.
Current Sensing	No integrated shunt amplifiers - requires external amplifiers or ADC for current feedback; matches cost-sensitive designs where sensing is handled externally.
Buck Regulator	Not integrated - distinguishes DRV8350H from DRV8350R; external 5-V/11-V supplies must be provided for DVDD and VGLS rails.

Pinout & Package

DRV8350HRTVR is housed in a 32-pin WQFN package (5.0 mm × 5.0 mm, 0.5-mm pitch) with exposed thermal pad for enhanced thermal dissipation in motor drive applications.

Pin/Terminal	Circuit Role	Design Meaning
INHA–INHC, INLA–INLC	Logic-level PWM inputs	Direct hardware control of all six gate outputs; supports 6x, 3x, 1x, or independent PWM modes without serial interface overhead.
GHA–GHC, GLA–GLC	Gate driver outputs	Drive N-channel MOSFET gates; high-side outputs use charge pump (CPH/CPL/VCP), low-side outputs reference GND.
VM, VGLS, DVDD	Power supply inputs/outputs	VM powers gate drivers (9–100 V); VGLS = 11-V LDO for gate bias; DVDD = 5-V LDO for logic (10-mA max).
nFAULT	Fault indicator	Open-drain output pulled low during any fault (UVLO, OCP, OTSD, etc.); requires external pullup for system-level fault signaling.
ENABLE	Global enable input	Active-low signal; asserts sleep mode (20 µA) and accepts 8–40 µs pulse to clear latched faults.
IDRIVE, MODE	Configuration resistors	IDRIVE sets peak gate current (7 levels); MODE selects PWM mode (4 levels); both use external resistors for pin-strapped flexibility.
VDRAIN, SHA–SHC, SLA–SLC	Sense inputs	VDRAIN monitors high-side drain voltage for V_DS OCP; SHA–SHC/SLA–SLC support external current sense or V_DS monitoring.

Key Features

Feature	Design Value
Smart Gate Drive (SGD) Architecture	Integrates V_GS handshake and minimum dead-time insertion to eliminate external shoot-through protection logic.
Adjustable Slew Rate Control	Reduces EMI by tuning gate drive edge rates via IDRIVE configuration - critical for EMC-compliant motor drives.
Charge Pump for 100% Duty Cycle	Enables continuous high-side conduction without bootstrap capacitor limitations - essential for field-oriented control (FOC) and regenerative braking.
V_DS Overcurrent Protection	Detects MOSFET short-circuit events directly via VDRAIN pin - faster than current-shunt-based OCP and immune to shunt tolerance drift.
Hardware-Only Interface	Eliminates SPI controller dependency and firmware complexity; ideal for resource-constrained MCUs or ASIC-based motor controllers.
Thermal Warning & Shutdown	Provides early overtemperature alert (OTW) before shutdown (OTSD), allowing graceful deceleration or fault logging in safety-critical motion systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar three-phase gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DRV8350SRTVR	Same 32-pin WQFN package and VM range, but uses SPI interface instead of hardware control; includes register-based configuration and diagnostics.	Requires SPI-capable MCU and firmware integration; better suited for systems needing dynamic parameter adjustment or fault logging.	Select DRV8350SRTVR when design flexibility, diagnostics, or multi-device daisy-chaining are required - not for minimal-firmware or cost-sensitive hardware-only control.
DRV8353HRTAR	40-pin WQFN package; adds triple integrated current shunt amplifiers (gain-selectable) and same hardware interface; no buck regulator.	Supports direct low-side current sensing without external op-amps; ideal for FOC or torque-controlled systems requiring phase current feedback.	Choose DRV8353HRTAR when integrated current sensing is needed - avoids external amplifier BOM and layout complexity, at the cost of larger footprint and higher unit price.

Compared with DRV8350SRTVR and DRV8353HRTAR, the DRV8350HRTVR offers the smallest footprint and lowest firmware dependency among the DRV835x family, making it optimal for fixed-function, high-volume motor drives where simplicity and cost are prioritized over configurability or sensing integration.

FAQ

What is the maximum VM supply voltage supported by the DRV8350HRTVR?

The DRV8350HRTVR supports a VM supply range of 9 V to 100 V, with absolute maximum rating at 105 V. This allows direct connection to common battery stacks used in e-bikes (36–72 V), cordless tools (18–60 V), and industrial 48–96 V DC systems - eliminating need for intermediate DC-DC conversion before gate driving.

Does the DRV8350HRTVR include an integrated buck regulator?

No, the DRV8350HRTVR does not include an integrated buck regulator. As the 'H' variant in the DRV835x family, it relies on external 5-V (DVDD) and 11-V (VGLS) supplies. In contrast, the 'R' variants (e.g., DRV8350R) integrate the LM5008A buck regulator capable of 2.5–75 V / 350 mA output.

How does the DRV8350HRTVR prevent shoot-through in three-phase bridge configurations?

The DRV8350HRTVR prevents shoot-through using Smart Gate Drive (SGD) architecture that enforces V_GS handshake logic and inserts minimum dead time between high-side and low-side switching transitions. This hardware-level protection operates independently of MCU timing accuracy or software delays - ensuring robustness even under controller fault or clock jitter.

What is the function of the nFAULT pin on the DRV8350HRTVR?

On the DRV8350HRTVR, the nFAULT pin is an open-drain output that pulls low during any fault condition - including VM undervoltage lockout (UVLO), gate drive supply undervoltage (GDUV), V_DS overcurrent, thermal shutdown, or shoot-through detection. An external pullup resistor is required to interface with MCU GPIO or system fault monitoring circuitry.

Can the DRV8350HRTVR operate in 1x PWM mode for sensored BLDC control?

Yes, the DRV8350HRTVR supports 1x PWM mode using an internal commutation table. In this mode, only three PWM inputs (INHA, INHB, INHC) are required, and the device automatically generates complementary low-side signals and manages timing based on Hall sensor inputs - simplifying MCU resource usage in trapezoidal control applications.
