LTC3300HLXE-2#PBF

LINEAR TECHNOLOGY  LTC3300HLXE-2#PBF  芯片, 电池监控器, 锂/LIFEPO4, LQFP48

The is an addressable high efficiency bidirectional multi-cell Battery Balancer 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. This fault-protected controller IC 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.
