I2C 隔離器

此參考設計為高壓側 N 通道 MOSFET 控制 (高達 32s) 電池組，且使用堆疊式 BQ769x2 電池監控器系列。此設計可監控每個電池芯電壓、電池組電流、電池芯和 MOSFET 溫度，並保護電池組，以確保安全使用。高壓側 N 通道 MOSFET 架構與最佳化驅動電路，可提供簡易的開關控制。此參考設計可實現低待機與運送模式耗電量，並可將兩組之間的電流差距最佳化。此參考設計適用於高電池芯數、高電壓及電池組應用。

This reference design provides a means to isolate I2C or SPI communication lines. This is often required in grid infrastructure applications such as protection relays and circuit breakers where high voltages are involved. This reference design provides both power isolation and signal isolation.

This reference design showcases a cost-optimized architecture that improves resolution of a binary-input module. A microcontroller unit (MCU) is shared between two-input channels (group isolation) to minimize the cost per channel. Wide-input range is covered using an amplifier with gain and (...)
