Part Number: DRV8703-Q1 Tool/software: We are currently trying to communicate with DRV8703-Q1 to get the Status Register details however the SDO line is always pulled high
The SPI is configured as follow:
CPOL=0 and CPHA=1
MSB first
Data width -16

Part Number: DRV8703-Q1 Tool/software: Hi Teams,
Regarding the datasheet description of DRV8703, it is stated that the SINK and SOURCE currents of the driving current can be configured through software. May I ask if it is necessary to connect resistors…
Part Number: DRV8703-Q1 Other Parts Discussed in Thread: DRV8705-Q1 Tool/software: Hi team,
When we tested the VDS overcurrent fault of DRV8703, we had the following two questions: 1. After the overcurrent fault occurs, the T retry time is 3ms, but in…
Part Number: DRV8703-Q1 Tool/software: Hello,
We would like to use the DRV8703 Gate Driver to drive 2 Solenoids. We would like to connect each Solenoid to a 1/2-half bridge. Thus we need to operate the Gate Driver in independent 1/2 Bridge control?!…
Part Number: DRV8703-Q1
Tool/software:
Attaching the Motor drive schematic. When the circuits related to Q35, Q36, Q4, Q3 is removed we see Motor fault. But when populated it is working. we identified that there is register control for the VDS fault…
Part Number: DRV8703-Q1 Tool/software: Hi,
In the design, we are using the DRV8703 to drive the motor.
Trying to set the gain as 78V/V using the 0x05H register but when measured gain is not matching.
The Rsense is 3m across SN, SP pin on the low side…
Part Number: DRV8703-Q1 Tool/software: I inserted the value from ''For example...'' into the formula for I (CHOP) on page 26 of the datasheet, but it did not yield 3.28 A.
Does this formula require any other elements?
Vref:3.3V VIO:0…
Part Number: DRV8703-Q1 Tool/software: Hi team,
We use DRV8703-Q1 in EPB, and found the low side MOSFET has a transient voltage change as shown in the below figue, can you help elaborate possible reasons?

Part Number: DRV8703-Q1 Other Parts Discussed in Thread: DRV8705-Q1 , Tool/software:
The H drive implementation in our board is shown as above. Two drivers are used for running two motors with the help of H-bridges. One leg of the H-bridge is made common…
