1 Introduction

The DRV8328 is a 4.5-V to 60-V triple half-bridge gate driver IC for motor drive applications. The DRV8328 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. The DRV8328 can also support up to 100% PWM duty cycle inputs with an integrated 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 1-1.

The DRV8328AEVM can be interfaced with the TMS320F280049C microcontroller on the LAUNCHXL-F280049C LaunchPad in correspondence with the reference software to provide the algorithm to the DRV8328 to control the BLDC motor.

This document serves as a startup guide to supplement the DRV8328AEVM + 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 DRV8328. For step by step details on connecting the LAUNCHXL-F280049C + DRV8328AEVM, refer to Section 4.
