Resolved! L6984 produce wrong voltage

Hello everybody,I need a power conversion DC-DC 24V to 3.3V. So I went to eDesign suite who recommendend me the following architecture:I reproduced it in my design: I produced the board, and when I apply 24V on the input, I obtain only 0.9/1V on the ...

Resolved! Motor driver

HelloI am using in my project both brush and brushless motor. My circuit works from 1 cell lion and have dc-dc step up to 6v for my motors.My sensorless brushless motor part number is : https://www.maxongroup.com/maxon/view/configurator/BOM:ECXZ08M1V...

My questions about EVAL-L9963 are following: Does it work with NiMH battery chemistry? Can it support each individual channel voltages of up to 14.4V nominal voltages (voltages may vary as high as 18.8V)? Can it perform passive and/or active balancing?

I am working on BMS type of system that will recondition, balance, and maintain NiMH HEV batteries. I'm considering to use L9963 IC and its accompanying evaluation board EVAL-L9963 for my prototype. My system consists of nickel-metal hydride battery ...
