Hi Steve, Thank you for the additional information. The high dV/dt transitions from the GHx signal look to be the cause of the transient observed in your initial post. I would recommend two possible...

Can you explain how the falling edge high dV/dt transitions of the GHx MOSFET causes a positive pulse on the output from the DRV8303?We did increase the gate resistors to 20 ohms, from 10; but it had...

RE: DRV8833: Sleep pin question
Thanks for the detailed reply.I changed the pull-down resistor value."Internally, the nSLEEP pin has a 500-kΩ resistor to GND"As stated above, I want to tie the sleep pin so the motor doesn't start...

DRV8833: Sleep pin question
Part Number: DRV8833Hi, I'm about to use the DRV8833CPWPR.This is my current schematic. I use the 9V battery to power the motor driver.I use CC3200 QFN MCU's PWM pins to control this.My questions...

Hi David, I am assuming you are concerned about the CC3200 Pad state after power up but prior to reset. Is that correct? I suggest you confirm the worst case pullup current with the CC3200 forum. This...

Hi Akash, What is different about the MOSFETs on the PCB vs the breadboard? Is the surrounding components the same? What is the PVDD voltage?

Hi Eli, No concern from a device standpoint on using a 2 Ohm resistor to trip at 100 mA. The 1 Ohm specification is assuming that the maximum current (1 A) is driven into the system. With a 1 Ohm...

Part Number: DRV8832In page 10, it is written that the maximum allowed resistor for current limiting is 1 Ohm. (Which is a bit different than what I find in other DRV88x family datasheets.)We need to...

Hi Robert, I'm sorry this part is giving you trouble. The response you're getting from the SPI fault registers is strange, in register 0x3, all of the device faults are set with 0xFFFF. Are you able to...

Hi Takahashi-san, Yes it is possible to use the DRV8844 as a 4ch low side switch. You can connect SRC12 and SRC34 directly to VNEG if current monitoring is not required. OCP are individually available...
