Bourns SM91572AL series automotive grade BMS signal transformer

The Bourns® model SM91572AL is an AEC-Q200 compliant, automotive grade, single-channel functional insulation transformer with integrated common mode chokes for battery management system (BMS) communication paths. The integrated common mode chokes eliminate the need for external filtering components, resulting in a shorter BOM for automotive and energy storage BMS designs. The transformer supports serial daisy-chain and IsoSPI communication and is developed for use with Analog Devices’ LTC681x, NXP’s MC33771/MC33772, and Texas Instruments’ BQ79616 devices.
