2 Introduction
The DRV8329 is a 4.5-V to 60-V triple half-bridge gate driver IC for motor drive applications. It provides a
bootstrap architecture to drive 3 high-side and 3 low-side N-channel MOSFETs with up to 1-A peak source
and 2-A peak sink current and can support up to 100% PWM duty cycle inputs with a trickle charge pump. All
variants are in compact QFN packages with hardware configurations and provide ultra-low sleep mode current.
Additionally, variants offer a variety of optional features including a dead time pin, overcurrent level pin, driver
shutoff pin, and integrated LDO capable of driving 3.3 V and 80 mA. A summary of the variants below can be
seen in
Table 2-1 .

Device Name LDO Output DRVOFF pin DT pin and VDSLVL pin PWM_MODE
DRV8329A 3.3 V Yes Available 6x
DRV8329B 3.3 V Yes Available 3x
The DRV8329AEVM can be interfaced with the TMS320F280049C microcontroller on the LAUNCHXL-
F280049C LaunchPad in correspondence with the reference software to provide the algorithm to the DRV8329
to control the BLDC motor.
This document serves as a startup guide to supplement the DRV83 LAUNCHXL-F280049C BLDC
motor control demo kit. It also is intended to help engineers design, implement, and validate reference hardware
and software for the LaunchPad MCU and DRV8329. For step by step details on connecting the LAUNCHXL-
F2 DRV8329AEVM, refer to
