Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: CSD88537ND Hello,
Need some direction on BMS architecture; specifically MOSFET selection. We have a board prototyped up, but its i too high cost due to the mosfet setup.
My thinking is to minimise…
Hi Mr. Koester,
Would you please send all of the internal register settings again? This did not appear.
Also, what components are being damaged on the board?
What is the VM voltage?
The BSC150N03 appears to have a Vds rating of 30V vs the CSD88537ND…
thanks for the reply, i just wanted to ask that theoretically the DRV8307 will not allow high side & low side mosfets to be turned on at the same time. When the low side mosfet is on what will be the expected power dissipation assuming RDSON = Ron and…
Jason,
We don't have anything at 40V. At 60V, we have the CSD88537ND.
The package is slightly different so we are currently investigating whether the two devices are footprint compatible and can use the same recommended PCB footprint.
Does this…
Hi Rick,
Thank you for your reply. I will let our engineer to do more test when change the register. And we also notice a interesting thing. We change the MOSFET CSD88539ND to CSD88537ND. Suddenly the issue are solved without adjusting the register…
Part Number: DRV8308 Other Parts Discussed in Thread: CSD88537ND Hi, TI expert
The customer is using ITOH DENKI's motor controller (see attached file below), but we are developing a new motor controller with the same performance as some functions are…
Hello Mr.Riveros
Thank you so much to reply quickly.
Risense value is 0.05Ω (same as Evaluate board)
TORQUE setting is 20h(32b)
ISGAIN setting is 5 (same as default setting)
Perhaps signal waveform is depend on characteristic of motor.
I write…
Hello James,
I check the EVM schematic. We have used MOSFET CSD18542KCS whereas EVM has used CSD88537ND. Comparing the gate charge of both, CSD18542KCS has Qg=44nC whereas CSD88537ND has Qg=14nC. I observed the waveform of gate voltages and output when…
Hello,
Is the device brought out of sleep mode? I suspect you need to write the UVLO bit to zero after powering on the device, or set RESET pin high then low.
Your external FETs shouldn't be the issue - their CSD88537ND QG is half the QG of…
Part Number: DRV8711 Other Parts Discussed in Thread: CSD88537ND Hi,
We've designed the DRV8711 onto our motor drive board. We are facing problems with SPI communication when the driver current is increased. At lower currents (200 mA) reads/writes of…
