3 Description
The Texas Instruments bq33100 Super Capacitor
Manager is a fully integrated, single-chip, solution that
provides a rich array of features for 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 × 6.4 mm in a compact 24-pin
TSSOP package, the bq33100 maximizes
functionality and safety while dramatically increasing
ease of use and cutting the solution cost and size for
Super Capacitor applications.
