Texas Instruments has introduced two new series designed to reduce the size and weight of motor drive applications.
When used together TI claims the DRV832x brushless DC gate drivers and CSD88684/99 NexFET power blocks require half the board space of other solutions at 511 square millimeters. The gate drivers feature a smart gate-drive architecture that eliminates up to 24 components used to set the gate drive current to adjust field-effect transistor (FET) switching.
When used together, the gate drivers and power MOSFETs deliver 700 watts of motor power without a heat sink, drive a peak current of up to 160 amps for more than 1 second, enable shorter trace lengths and prevent unintended FET turn-on, and the switch-node clip helps eliminate parasitic inductance between high- and low-side FETs.
The combination of devices can be used to design smaller and lighter power tools, integrated motor modules, drones and more.
