LTC3300HLXE-2#WPBF

LTC3300-2 is a fault-protected controller IC for transformer-based bidirectional active balancing of multicell 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 device can balance upto 6 series-connected battery cells with an input common mode voltage upto 36V. Fault protection features include readback capability, cyclic redundancy check (CRC) error detection, maximum on-time volt-second clamps, and overvoltage shutoffs. It is used in application such as electric vehicles/plug-in HEVs, high power UPS/grid energy storage systems, general purpose multicell battery stacks etc.

• Bidirectional synchronous flyback balancing of upto 6 Li-Ion or LiFePO4 cells in series
