DESCRIPTION  
The Texas Instruments bq33100 Super Capacitor  
Manager is a fully integrated, single-chip, solution that  
provides a rich array of features for managing, charge  
control, monitoring, and protection, for either 2, 3, 4  
or 5 series Super Capacitors with individual capacitor  
monitoring and balancing or up to 9 series capacitors  
with only the stack voltage being measured. With a  
small footprint of 7.8 x 6.4 mm in a compact 24-pin
