RS Components has announced availability of a pair of BMS (battery monitoring system) signal transformers from Bourns.
The Bourns SM91501AL and SM91502AL are shipping from RS in the EMEA and Asia Pacific regions.
The new SM91501AL and SM91502AL are dual- and single-channel isolation transformer modules, respectively, with both devices offering common-mode chokes for noise rejection in BMS applications. Offering compliance with the AEC-Q200 standard for automotive applications, the modules are also implemented in reference designs with Analog Device’s LTC6804-1/6811 and NXP’s MC33771/33772 battery monitoring devices.
Further electrical characteristics include working voltages of 1600Vdc and 1000Vdc for the SM91501AL and SM91502AL, respectively, and a 4300V DC high-potential isolation voltage. Other features of the models include an extended temperature range from –40 to +125°C; support for serial daisy-chain isoSPI communication; and compliance with the RoHS directive.
