Hello,
I am using the FRDM33771 together with the battery emulator.
I want to test cell balancing and measure current for SOC however when I enable the cell balancing I see no difference regarding the voltages and the current measurement seems wrong also.
When I enable MEAS_ISENSE I can't change the voltage with the emulator and it keeps -157.286 mV.
Do I have to connect an external shunt resistor or is it already inside the emulator.
See the attachment for further information.
Thank you
Hi
How do you operate about enable MEAS_ISENSE?
For the emulator the current sense output voltage can vary from around −150 mV to +150 mV.
This output is not designed to drive a large current since the current sense input from the MC3377x needs
as little as 100 nA. If more than 1 μA is pulled from this output, the voltage may drop by a
few mV.
