DRV8353SRTAR Multiphase motor driver, three-phase BLDC motor controller
The DRV8353SRTAR from Texas Instruments (TI) is a highly integrated three-phase motor driver IC designed for brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) control applications. Housed in a compact 40-pin QFN package, this device combines a gate driver, buck regulator, and advanced protection features into a single chip. It supports a wide input voltage range of 8–60V and delivers up to 70V absolute maximum voltage tolerance, making it suitable for high-power systems. The DRV8353SRTAR integrates three half-bridge drivers with adjustable gate drive current, enabling compatibility with N-channel MOSFETs or IGBTs. Its SPI interface allows flexible configuration of parameters such as dead-time, drive current, and fault diagnostics, ensuring adaptability across diverse motor control scenarios.
DRV8353SRTAR Key Features
The DRV8353SRTAR stands out with its integrated smart gate drive architecture, which reduces external component count and simplifies PCB design. It features programmable slew-rate control to minimize EMI and optimize switching losses. The chip includes a 1.5A buck regulator to power external controllers, eliminating the need for an additional voltage regulator. Advanced protection mechanisms such as overcurrent (OCP), undervoltage (UVP), overtemperature (OTP), and shoot-through prevention ensure system reliability. Additionally, its current-shunt amplifiers support both low-side and high-side sensing with adjustable gain, enabling precise motor current monitoring for closed-loop control.
DRV8353SRTAR Applications
This motor driver is ideal for high-performance applications requiring robust control and efficiency. Common use cases include electric vehicles (e-bikes, scooters), industrial automation (robotic arms, conveyor systems), power tools (drills, saws), and HVAC systems. Its ability to handle high voltages and currents also makes it suitable for drones, servo drives, and renewable energy systems like solar trackers. The DRV8353SRTAR's diagnostic features and fault reporting further enhance its suitability for safety-critical environments.
DRV8353SRTAR's Selection Advantages
Choosing the DRV8353SRTAR offers a balance of integration, flexibility, and cost-effectiveness. Its built-in buck regulator and gate drivers reduce BOM complexity, while SPI programmability allows customization without hardware changes. Compared to discrete solutions, it improves thermal performance and system reliability. The device's compatibility with multiple motor types and control methods (sensorless/sensored FOC, trapezoidal control) ensures scalability across projects. Engineers benefit from TI's comprehensive design resources, including reference schematics, simulation models, and GUI-based configuration tools.
Alternative Models
For lower-power requirements, consider the DRV8353F (with hardware interface instead of SPI) or the DRV8305 (supports 45V max). Competing alternatives include Infineon's IRAM136-3023B (integrated inverter module) and STMicroelectronics' STDRIVE601 (three-phase driver with similar voltage range). For applications needing higher current, TI's DRV8350RHAR (100V rating) or DRV8343 (70V with integrated current sensing) may be suitable.
