LTC®6820 可通过单个双绞线连接在两个隔离器件之间提供双向 SPI 通信。每个 LTC6820 将逻辑状态编码为信号,并跨越一个隔离势垒将信号传送至另一个 LTC6820。接收 LTC6820 对传输信号进行解码并把从总线驱动至适当的逻辑状态。隔离势垒可利用一个简单的脉冲变压器进行桥接,以实现几百伏的隔离度。

LTC6820 采用匹配的供电和吸收电流来驱动差分信号,从而免除了增设变压器中心抽头的需要并降低了 EMI。接收器中的高精度窗口比较器负责检测差分信号。驱动电流和比较器门限由一个简单的外部电阻分压器设定,因而使得系统能够针对所需的电缆长度和期望的信噪比性能实施相应的优化。

12 Cell 4A Controller Board Bi-Directional Active Cell Balancer with LTC3300-1, LTC6804-2 and LTC6820

产品详情

Demonstration Circuit DC2100B-D is a stackable, bidirectional cell balancer slave board using the LTC6804-2 and the LTC3300-1 ICs to achieve active balancing of up to 12 Li-Ion cells. It requires the DC2100B-C for proper operation. The DC2100B-D uses a single LTC6804-2 Multi-Cell Addressable Battery Stack Monitor IC to measure cell voltages and two LTC3300-1 Synchronous Flyback ICs to provide active cell balancing. The DC2100B-C controller board contains a PIC18F47J53 microcontroller, the LTM2884 isolated USB transceiver, the LTC6804-2, two LTC3300-1 ICs, and the LTC6820 isoSPI Interface IC to facilitate isolated communication. Up to seven DC2100B-D boards can be connected to a DC2100B-C to build a stacked system of eight total boards.
