DRV8703-Q1 EVM User’s Guide
WARNING
Hot surfaces include the power MOSFETs (Q3-Q8), power sense
resistors (R74-77), and areas around them.
The DRV8703-Q1 EVM serves as an evaluation kit to demonstrate TI’s DRV8703-Q1 H-bridge gate driver
in a 3.5-in × 2.2-in compact form factor. An MSP430G2553 device is used to control the speed and
direction of the motor, while also monitoring the motor current from the DRV8703-Q1 device. The power
stage is created using the DRV8703-Q1 H-bridge gate driver and the CSD18540Q5B N-channel
NexFET™ power MOSFETs. The EVM is a high-performance, power-efficient, and cost-effective platform
that speeds development for a quicker time to market.
