TI Korea (CEO Kent Chon, www.ti.com/kr) July 2, 2015 – TI (CEO Kent Chon) announced the launch of an integrated gate driver product with adjustable gate drive settings. The new DRV8701 can flexibly drive a wide range of external FETs (field-effect transistors) and supports various motors, speeds, and varying loads. Additionally, it provides a flexible platform capable of supporting various types of brushed DC motor models with a single gate driver in equipment such as white goods, home appliances, robots, home automation, power tools, industrial pumps, and valves.

The DRV8701 brushed DC gate driver features adjustable gate drive capability and integrates advanced protection functions and other components, enabling a single device to replace up to 45 discrete components, allowing for smaller and more robust designs.

Key Features and Advantages of DRV8701 Gate Driver

·System Flexibility and Scalability: Using the DRV8701, designers can flexibly select external FETs, easily adjust FET slew rate by raising or lowering gate drive current, optimize system EMI (electromagnetic interference) performance, and provide additional system protection without external resistors/capacitors.

·Board Space Savings and Reduced System Complexity: By integrating two LDO (low-dropout) regulators, current sense amplifiers, and comprehensive protection functions, system board space can be reduced by up to 40% compared to competitive products and discrete solutions.

·Achieve Higher System Reliability: In addition to robust on-chip protection functions including undervoltage lockout, overcurrent, shoot-through, and thermal shutdown, it includes advanced features such as charge pump undervoltage, gate drive fault, and individual FET VDS monitoring to protect external FETs.

·Wide Operating Voltage: Provides a wide motor supply voltage range of 5.9 to 45V, supporting industry-standard 12V and 24V power supplies.

Tools and Support

Engineers can test the new gate driver in their systems using the DRV8701EVM evaluation module. This evaluation module integrates the MSP430G2553 ultra-low-power microcontroller and CSD18532Q5B NexFET power MOSFET, and supports a maximum current of 15A in a business card-sized compact form factor. It is currently available for purchase at $49 through the TI store and authorized distributors.

For brushed DC motor design, engineers can find solutions to problems, receive assistance from fellow engineers and TI experts, and share knowledge and solve issues on the Motor Driver Forum in the TI E2E™ community.

Pricing and Availability

The DRV8701 is currently available in a 4mm x 4mm QFN (quad flat no-lead) PowerPAD™ package. It is a thermally enhanced standard-sized package that does not require bulky heat sinks and slugs. Pricing starts at $0.92 at 1,000-unit quantity.

The DRV8701 is a new addition to TI's motor driver portfolio. TI offers a comprehensive range of motor solutions with various voltages, currents, interfaces, integration levels, and control options, from simple drop-in and spin motors to highly complex industrial motors.
