I am trying to make a charger circuit for a battery pack consisting of 6 lithium ion batteries (cells) in series. Many battery charger ICs support multi-cell charging but do not provide cell balancing or protection. How should I connect the charger IC, a balancer IC and a protection IC (the last 2 could be in one IC I guess) with the cells?

Also, is there a single IC that handles battery pack charging, balancing, and protection?

    \$\begingroup\$ There are multi-cell charger IC's that provide cell balancing. You merely have to use the right search terms. \$\endgroup\$ – Sparky256 Feb 15 at 19:57

    \$\begingroup\$ Intersil (now Renesas) has a bunch of these. \$\endgroup\$ – yhyrcanus Feb 15 at 20:32
  • \$\begingroup\$ I did a lot of searching and the ones I found do not support 6-cell packs (including Renesas). Please give me an example instead of criticizing how I search. \$\endgroup\$ – Yosry Feb 15 at 23:13
  • \$\begingroup\$ A Bing search of "liion 6 cell balance ic" brings up several candidates ...so maybe your search is flawed. \$\endgroup\$ – Jack Creasey Feb 16 at 0:19
  • \$\begingroup\$ What comes up is a group of battery monitoring/balancing ICs, not chargers with balancing capabilities. \$\endgroup\$ – Yosry Feb 16 at 0:34
