could you help tell me what the difference between ADuM5201CRWZ and ADuM5201WCRWZ is?
ADuM5201CRWZ has 500mW output power but ADuM5201WCRWZ just only output 400mW.
and both have the same operating temperature range of -40C to +105C.
I just guess they are the same die, but automotive-qualified parts should be tested with stricter conditions, am I right?
but why does WCRWZ has less output power than CRWZ?
The ADuM5201W has a thicker insulation barrier process. The thicker barrier causes lower efficiency than the industrial grade. Due to the thermal limitations of the SOIC packaging, the output is de…
Both parts are specified for 100mA isolated supply output with 5V nominal on the primary side. See Tables 2 & 10 DC-to-DC Converter Static Specifications in both datasheets.
There is a difference in Abs Max tables between the ADuM5401 and ADuM5401W. The output of the ADuM5401W is derated with ambient temperatures above 85C.
Thank you for your kindly help.
I checked ADuM5041 and ADuM5401W which are the same output current as you said.
But, Table 2 in ADuM5201W' datasheet shows an 80mA output supply, it seems like different from ADuM5201.
If i missed the datasheet, sorry, and please let me know.
The ADuM5201W has a thicker insulation barrier process. The thicker barrier causes lower efficiency than the industrial grade. Due to the thermal limitations of the SOIC packaging, the output is de-rated.
If the application needs an automotive grade and more than 400mW, the ADuM5401W-1 would be the part to consider.
