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.
Part Number: DRV8702-Q1EVM Other Parts Discussed in Thread: DRV8702-Q1 , Hi team,
Recently I study the DRV8702-Q1 and make an experiment that use the DRV8702-Q1EVM to drive a brush motor, then I have some questions as follows,
1. ch1: pin-IN1/PH,…
Hi Hector,
Thanks for your reply. It seems that there is documentation issue in DRV870x-Q1 datasheet.
"Section 7.5.1.1 of datasheet DRV8702-Q1, DRV8703-Q1 SLVSDR9D –OCTOBER 2016–REVISED DECEMBER 2018" has conflicting statements for SPI mode configuration…
Part Number: DRV8703-Q1 Other Parts Discussed in Thread: DRV8702-Q1 , I am using a DRV8703-Q1 (SPI version of the DRV8702-Q1) in a 12V automotive application.
We are seeing a failure rate between 10-30% in a larger prototype batch of boards (sample…
Hi Roy,
The DRV8701 can operate at frequencies from 0 Hz to 100kHz, but is not automotive qualified.
For automotive devices, please consider the DRV8702-Q1 or DRV8703-Q1. These have the following specifications:
Application : Automotive (PTG motor…
Hi Kun,
Is this the device you are evaluating a DRV8702D-Q1 or DRV8702-Q1?
Can you confirm the signal names in the images? SL2 should not be 10V. Channel 3 appears to be GH and ch 4 appear sto be GL?
What is ch 1?
When you say GH1 and GH2…
Part Number: DRV8702-Q1EVM Other Parts Discussed in Thread: DRV8702-Q1 I'm thinking getting a few of these boards to control electric motors in the vehicle using Arduino Mega, is it possible to do so? Is there any pin out on the board to control speed…
Hello,
I have find out this following EVM boards & read all the document files related to this boards so out of all boards I can see input voltage range or Operating Voltage Range of this boards but in that document files I'm not able to find that EVM…
Hi FRAMziskus,
You are not missing anything.
Options are limited above 50V. One possible option is to use the DRV8702-Q1 or DRV8703-Q1 connected to automotive half bridge drivers to reach the higher voltage.
