Part Number:SN65472-EP
您好,查询SN65472-EP的规格书发现如下一句解释,想请问exposed (power) pad 这里的意思是散热盘与PCB的power连接吗?我们常见的是与GND地连接,还请帮忙确认下,
另外这个exposed (power) pad是与芯片内部的GND相连接吗?谢谢
The junction-to-case (bottom) thermal resistance is obtained by simulating a cold plate test on the exposed (power) pad. No specific JEDEC standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.

SN65472-EP 并无芯片底部的Powerpad.
常见的芯片底部有Powerpad的电源芯片,Powerpad与GND是需要链接的,在芯片内部也是连接。
