SPV1050 current limiting relationship to Veoc

I have an SPV1050 configured as follows:R4 = 6.2MR5 = 1MR6 = 3.9MVeoc = 3.5VVuvp = 2.78VThe device is configured for boost mode with MPPT set to 75% and Vin = 2V. The device works as expected, except that it will only draw the full specified 70mA cu...

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 ...
