Part Number: DRV8703-Q1 My customer is asking the following questions concerning the DRV8703-Q1:
We will be using SPI to program the gains and thresholds. But initially we thought to make sure we drive the motor through hardwired signals.
So, the…
Part Number: DRV8703-Q1 Dear, Sir.
The design at my customer side using DRV8703-Q1 is proceeding well.
So they have started the reviewing of protection functiions which DRV8703-Q1 has.
I would like to make sre as followings to make clear answers…
Part Number: DRV8703-Q1 Dear, Sir.
My customer is using just 1 SPI slave on their system.
So, They would like to connect nSCS to GND immediately, and asking that.
I understand nSCS internally pull-downed.
Is it no problem to connect nSCS to GND…
Part Number: DRV8703-Q1 Dear, Sir.
My customer is evaluating DRV8703-Q1. During that, They are facing following
symptom on /SLEEP & /FAULT.
/FAULT Glitch(LOW) during aprox. several 100us ~ 1ms can be observed at
/SLEEP LOW<=>HIGH.
1. Is it…

As I was working with the DRV8703-Q1EVM, the sense amplifier output showed a large spike a few microseconds after the PWM goes high. I was able to remove this spike…
Part Number: DRV8703-Q1 Hi
I read the following in datasheet:
"Mode control pin. Pull this pin to logic low to use H-bridge operation. Pull this pin to logic high for independent half-bridge operation. This pin is connected to an internal resistor…
Part Number: DRV8703-Q1 Dear, Sir.
Regarding VDS Threshold Resister Setting as below, My customer is feeling strange the value
shifting from 011b=0.2V to 100b=0.12V.
They would like to double-confirm the description is really correct.
Sorry…
Part Number: DRV8703-Q1 Dear, Sir.
I tried to create the relation of OTW/OTSD bits & nFAULT as below.
Is there my miss-understanding which must be corrected?
Please give your advice.
