Hello,

For CSD18543Q3A as there is 3 source pin can you plaese confirm

1) Can we use one source pin (S1) for driver

2)Can we use remaining 2 source pin for sharing load .For example our load is 6A so S2 will carry 3A and S3 will 3A

3)Please share if you have any recommendation for same

Hello Pranjali,

It's nice to hear from you again. The 3 source pads on the device are internally tied together on the lead frame. Normally, those pads are connected to a common copper shape on the PCB. There is no inherent load sharing between pins. I don't think there is any benefit of separating the pins. Please let me know if you have any questions.

Best Regards,

John Wallace
