Overview
The DRV8301DCAR, produced by Texas Instruments, is a three-phase gate driver IC designed for motor drive applications. This device is particularly suited for driving three-phase brushless DC (BLDC) and permanent magnet synchronous motors (PMSM). It integrates three half-bridge drivers, each capable of driving two N-channel MOSFETs, and supports a wide operating supply voltage range from 6 V to 60 V. The DRV8301DCAR features a bootstrap gate driver architecture with trickle charge circuitry, enabling 100% duty cycle operation. It also includes automatic handshaking to prevent current flow during MOSFET switching and integrated VDS sensing for overcurrent protection.
