EM1402EVM: EM1402EVM

Part Number: EM1402EVM

Hi,

I have some questions about EM1402EVM.

1) In the EM1402EVM datasheet shows an image were the external power supply is 12V/24V but then it says that the positive external isolated balance source input is 12V. What is the correct value or is a range of values between 12V and 14V? What happend if the external power supply is less than 12V? The device turn off immediately?

2) Can the EM1402 EVM performs a balance (charge or discharge of one cell) when the Battery Module is being externally charged? Is there is any risk?

Thanks.

Hi user,

Our recommendation is to use the 12V battery as this was how our testing was completed. You can perform charging while balancing.

I understand, but if the system supports a 12 / 24V battery, can it work with a 24V battery and less? Can there be a problem?

Thanks

Hi User,

In theory, it should be okay but as I mentioned we cannot recommend using it this way as we did not do characterization and so we cannot guarantee datasheet specs. You would have to perform your own characterization.

Taylor
