All associated gate drive circuitry, precision current sensing, fault detection circuitry and a robust serial interface with built-in watchdog timer are integrated.
Each LTC3300-2 can balance up to 6 series-connected battery 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.
Each LTC3300-2 has an individually addressable serial interface, allowing up to 32 LTC3300-2 devices to interface to one control processor.
Fault protection features include readback capability, cyclic redundancy check (CRC) error detection, maximum on-time volt-second clamps, and overvoltage shutoffs.
The related LTC3300-1 offers a serial interface that allows the serial ports of multiple LTC3300-1 devices to be daisychained without opto-couplers or isolators.
