Hi Richard,
Many thanks for the help.
I have since tried another MOSFET type with a much faster body diode recovery time of 50nS (CSD18537NKCS) but unfortunately the heating problem has persisted. This is with the gate and source connected as before…
Part Number: UCC27211A-Q1 Other Parts Discussed in Thread: CSD18537NKCS , , UCC27282 Hi,
I'm using UCC27211A-Q1 to drive two N-channel MOSFETs (CSD18537NKCS) synchronously. I want to reduce the ripples for the switching waveform. Please find the attached…
Thank you very much for your reply. And sorry about the confusion, I was using CSD18537NKCS for my MOSFETS rather than BSC160N10NS3. Besides, is there any protection I can use on my circuit? Since the motor is really inductive, I'm worried about when…
Hello William,
What is needed here is a 'Transient Thermal Impedance' chart, where the x-axis is time in seconds and the y-axis is Effective Zθ(J-C), for this particular package.
While this 'Transient Thermal Impedance' chart is a fairly typical thermal…
Hello Clinton,
I'm still trying to fix this issue. Yes. If I add a fan blowing directly to the board the current eventually settle out.
I put my design requirements on Webench with a 3.2A output current(tried with 3.4 but it didn't find a suitable…
Hello, thank you for your prompt reply.
We are also considering to use CSD18537NKCS with TPS40170.
On this case, I assume that the required RILIM would be;
RILIM = IOC*RDS(on)/IILIM = 3A*14mohm/9.0uA = 9.3kohm
Please let me clarify whether my…
Attached is my schematic for my Li-Ion Battery charger. Some notes on the design:
Adapter Input Voltage is 12 VDC.
Battery consists of two series NCR16850B batteries at 7.4Volts.
Appreciate any questions or comments.
Thanks,

Although I still need to use power line to transmit the data about the motor's speed or something else to control the motor.
So, do I need to buy a new device or any software I can use?
if you wish implement motor control…
