Archie,
It's hard to tell anything from this waveform. It seems that nFAULT does not go LOW. Also, the value measured here does not match the voltage measured by the customer in previous response.
May I recommend ordering a new EVM and trying to see…
Part Number: DRV8803EVM Other Parts Discussed in Thread: DRV8803 Tool/software: Code Composer Studio Hello,
I am currently trying to drive a solenoid (1.2W max/ 24V power supply) using the DRV8803EVM with PWM inputs generated from the TM4C1294XL Launchpad…
Part Number: DRV8803EVM Other Parts Discussed in Thread: DRV8803 , EK-TM4C1294XL , , DRV8804EVM Tool/software: Code Composer Studio Hello,
I am trying to write code on the EK-TM4C1294XL that will produce a PWM wave that controls the DRV8803 on the DRV8803EVM…
Part Number: DRV8803EVM Other Parts Discussed in Thread: MSP430F2617 , DRV8803 I have a DRV8803EVM module and would like to modify the firmware in the MSP430F2617.
According to the TI website on this Eval kit, the MSP source code is included in the Evaluation…
Hi Tor,
I tried to duplicate your finding on a DRV8803EVM and was not able to.
The DRV8803EVM was reconfigured to eliminate any additional current paths such as regulators, mcu, etc.
In all cases (nENBL high/low, nRESET high/low, INx high/low) with no…
Gamze,
The thermal performance is relied on the PCB layout a lot. The datasheet gives the thermal resistance.
The power loss can be estimated by Rds(on) x Load current x Load current.
After we know the power loss and the thermal resistance, we can…
Hi Alex,
The datasheet states 0.8A per channel continuous.
What evb is being used? If it is not the DRV8803EVM:
what is the size of the evb?
what is the copper thickness?
how are the 6 ground pins of the DW package connected to the board…
Hi Shinichi-san,
Shinichi1 said: 1) the value of R and L at the test
Test 1 -- Inductor is 100uH, 14A, resistance of 20mOhm. Two test clips of 30mOhms and 200nH each connected the inductor to VM and OUT4.
Total inductance is 100.4 uH and total resistance…
