Part Number: DRV8703-Q1 Dear Sir.
My customer is evalating DRV8703-Q1 as brushed motor pre-driver for their system.
At this time, OEM pointing out the GND level difference between DRV8703-Q1 GND
and Motor GND. It may be around 1 ~ 1.5V.
DRV8703…
Other Parts Discussed in Thread: DRV8873-Q1 , DRV8873 , DRV8701 Hi,
We are designing a respirator using brushed DC motor. Motor is 12V 6A rated. Can I use DRV8873-Q1 for this purpose or should I use DRV8703 with external N channel MOSFETs. And which…

Hi,
Please resolve the following issues as early as possible
1.While connecting DRV8703 q1 evm board ,'NO USB FET was FOUND ' like this error was coming..i tried a lot methods which are suggested in forum and also in…
Hello CHO SR,
Answer 1: Ta=85C, if we assume the board allows 125C maximum temperature, the maximum temperature rise is 40C. According to DRV8873-Q1 27.8C/W RθJA, the maximum allowing power dissipation is about 1.43W. DRV8873-Q1 FETs total Rds_on is…
Part Number: DRV8873 Other Parts Discussed in Thread: DRV8702-Q1 , DRV8703-Q1 Hi team,
Customer asked that the drive current of the DRV8873 was insufficient. Is there a chip with higher current?
Thanks.

Thanks for responding to my previous forms.
we want to control DRV8703-Q1 driver IC in DRV8703D-Q1EVM ( Evaluation Module ) with external micro, so as per…
Part Number: MSP432P401R Other Parts Discussed in Thread: MSP430G2553 Tool/software: TI-RTOS Hi,
I am trying to work out the SPI communication between two evaluation boards , MSP432P401R (Master) and MSP430G2553 (Slave). My main goal is to check if…
Hi Benjamin,
Please refer to Figure 43 of the DRV8703-Q1 datasheet. This shows the typical configuration of the charge pump.
You can see the max voltage across the capacitor will be VM - Vfd when CP1 is set to 0V.
This is the reason the CP1/CP2…
Hi Vino,
The DRV8881 has internal FETS and cannot be used to drive external FETs.
We have the following devices available to drive external FETs
DRV8701 DRV8702-Q1 DRV8703-Q1 DRV8704 -- dual motor gate driver
Please consider these.
