Charging SuperCap with LT8611 for backup.

Question asked by rokobert on May 6, 2018

Is it good choice to use LT8611 for charging string of 6 supercaps (in series) each 100F/2.7V. Maximum charging current is 500mA and end voltage is 15.6V. Then those caps are for supplying electronic (MCU + motor control). 

What I must be carefull about when supply voltage is off and caps are full?

How big will be drain current from caps to SW pin when LT8611 is disabled?

 

Thanks in advance!
