Part Number: DRV8703-Q1EVM Other Parts Discussed in Thread: DRV8703-Q1 , Dear Support team,
Our customer will use DRV8703-Q1 in their application. They are using the DRV8703-Q1EVM to check the occurrence of a flag when a fault is detected. Please tell…
Part Number: DRV8703-Q1EVM Other Parts Discussed in Thread: DRV8703-Q1 Hai,
Thanks for responding my previous queries.
In the DRV8703-Q1 EVM board the H-bridge connected to the driver IC seems like operating in the HIGH SIDE DRIVE configuration. The…
Part Number: DRV8703-Q1EVM Hai,
Thanks for responding my previous forums.
As per your suggestion I removed resistors between micro and driver IC of IN1 and IN2 pins, because I want to drive the motor with external micro by providing PWM to IN2.

Hi Huan,
A common reason UVLO can occur is when large or varying loads draw large amounts of current which can cause the supply voltage to dip. Having a sufficient amount of bulk capacitance on the supply voltage will reduce the amount the supply voltages…
Part Number: DRV8703D-Q1 Other Parts Discussed in Thread: DRV8703-Q1 , DRV8703-Q1EVM The DRV8703-Q1 datasheet clearly specifies the SPI mode configuration (mode 1).
After hours of debugging our board, we decided to probe the D RV8703-Q1EVM dev board…
Hi Huan,
Yes the PWM is usually generated by a microcontroller. This is required only if you'd want to have a PWM speed control. Applications that don't need speed control can be controlled by SPI IN1 and IN2. The DRV8703 does not have internal PWM…

Hi Tommy,
Understood. To be very positive that there will not be any problems with the frequent current direction changes, I recommend testing it on one of our evaluation boards (DRV8703-Q1EVM). Plus it would be good to drive your load with our eval…
