What are the characteristics of BMS signal transformers with different signals?

As for BMS signal transformer, I have introduced it in the article "What are the characteristics of BMS signal transformer?". Today I will take you to understand the characteristics of BMS signal transformer with two different signals, SM91509AL and SM91508AL.

SM91509AL is a dual-channel isolation transformer module, including common-mode choke, used to suppress noise in BMS applications. It is well matched with the BQ79606 daisy chain communication of Texas Instruments, and is AEC-Q200 compatible. It also provides 1600 V (DC) operating voltage, 4300 V (DC) hi-pot isolation, and an extended operating temperature range of - 40 ° C to+125 ° C.

SM91508AL is a single-channel isolation transformer module, including common-mode choke, used to suppress noise in BMS signal applications. It supports serial daisy chain/IsoSPI communication and is AEC-Q200 compatible. BMS transformer provides 1000 V (DC) operating voltage/4300 V (DC) hi-pot isolation voltage and extended operating temperature range from - 40 ° C to+150 ° C.

SM91509AL series features:
