    Smallest Gate Driver and Power MOSFET solution by TI for Motor Control

    Tools and support to jump-start design

    In addition to the 18-volt BLDC motor reference design, engineers can search for other motor reference designs that use the power blocks and gate drivers to help solve their system design challenges. The three-phase smart gate-driver evaluation module (EVM) allows designers to drive a 15-A, three-phase BLDC motor using the DRV8323R gate driver, CSD88599Q5DC power block and MSP430F5529 microcontroller LaunchPad development kit. The EVM is available from the TI store for US$99.00.

    Package, availability and pricing

    The new DRV832x BLDC smart gate drivers offer peripheral and interface options for engineers to select the best device for their design: with or without an integrated buck regulator or three integrated current-shunt amplifiers. Each device option is available in a hardware or serial interface and comes in quad flat no-lead (QFN) packaging. The CSD88584/99 power blocks come in DualCool small outline no-lead (SON) packaging, with 40- or 60-V breakdown voltage (BVDSS) choices. All devices are available now, priced and packaged as listed in the table below.
