High Efficiency Bidirectional
Multicell Battery Balancer
DESCRIPTION
The LTC®3300-1 is a fault-protected controller IC for
transformer-based bidirectional active balancing of multi-
cell battery stacks. All associated gate drive circuitry,
precision current sensing, fault detection circuitry and a
robust serial interface with built-in watchdog timer are
integrated.
Each LTC3300-1 can balance up to 6 series-connected bat-
tery cells with an input common mode voltage up to 36V.
Charge from any selected cell can be transferred at high
efficiency to or from 12 or more adjacent cells. A unique
level-shifting SPI-compatible serial interface enables
multiple LTC3300-1 devices to be connected in series,
without opto-couplers or isolators, allowing for balancing
of every cell in a long string of series-connected batteries.
When multiple LTC3300-1 devices are connected in series
they can operate simultaneously, permitting all cells in
the stack to be balanced concurrently and independently.
Fault protection features include readback capability, cy-
clic redundancy check (CRC) error detection, maximum
on-time volt-second clamps, and overvoltage shutoffs.
