Can you safely review this Digital Isolator?

OwainM

Hey everyone,

I'm trying to work out how suitable the Toshiba DCM340L01  is for a RoadTest and would appreciate your input.

Reading through the datasheet it seems quite interesting, but due to the voltage it claims to be able to insulate from (5000Vrms), I'm not sure what equipment is required to put it through its paces.

What additional equipment might you need for a RoadTest?



Rather than just the IC alone, the chip is provided on a break-out board, as shown below.

The following documentation for the chip is provided from the manufacturer:

  • It's not a very good candidate for a road test.

    I use isolators in many designs and buy them from reputable suppliers. usually TI or Analog Devices, but sometimes others, including Vishay and Toshiba.

    I expect such parts to perform as described and specified in the data sheet.If the supplier can't be trusted it would be necessary to 100% test any such parts used.

    The design of the board can seriously compromise the function of the isolator.

    Testing one part on a demo board proves almost nothing.

    Testing one part in your application may prove that the complete design is (or maybe is not) capable of working as intended.

    The problem with these parts is that their function is not very exciting for a road test and the gear required to do a decent test is expensive - the value of the part is not a significant incentive.

    (Unlike, for example, a cheap board with a novel sensor or processor chip where the testing demands mainly the effort of the reviewer rather than the gear that they own.)
