Other Parts Discussed in Thread: TPS2660,
Hello Team,
I request you to please provide me some technical feedback on hot-swap design for this Two-phase stepper motor (0940 series, parallel configuration) .
Here is the schematic of the hot-swap:
My questions:
1. Is the power MOSFET in the circuit good enough for this particular design using to drive the above motor operating at 24V and 0,94 A per phase (its a two phase stepper motor)? According to the datasheet, The MOSFET has the parameters 30V and 3A, so i presume that should be suitable but the power dissipation is only 1W. So just wanted to make sure if this is too low for the application. I understand that the MOSFET has to operate in its SOA and power limiting function in the hot-swap helps achieve this. But what should be the maximum power dissipation parameter of the MOSFET ? will it destroy teh MOSFET in my case?
2. Also, please consider skimming through the other components like sense resistor, diodes and so on. Just in case if there are any discrepancies found please let me know with the design. Thanks a lot.
Regards,
Nik
