Texas Instruments DRV8329AEVM | Demoboard DRV8329AEVM

Description

The DRV8329AEVM is a 30-A, 3-phase brushless DC drive stage based on the DRV8329A gate driver for BLDC motors. The DRV8329 incorporates three diodes for bootstrap operation without the need for external diodes. The device includes a current shunt amplifier for low-side current measurement, 80-mA LDO, dead time control pin, VDS overcurrent level pin, and gaet driver shutoff pin. The EVM includes switches, potentiometers, and resistors to evaluate these settings as well as configurability for the A variant (6x PWM) and B variant (3x PWM) of the DRV8329 device.Up to 60 V can be supplied to the EVM, and the DRV8329's integrated LDO generates the gate voltage needed for the bootstrap GVDD supply. Status LEDs for all power supplies as well as a Fault LED are included for user feedback. The C2000 launchpad (LAUNCHXL-F280049C) is required for this kit and is used to control the DRV8329AEVM with a sensored trapezoidal algorithm, as well as to monitor and report faults.
