Toshiba has launched an all-new TLX9152M automotive photorelay with an output withstand voltage of 900 V (min), highly suitable for application in high-voltage automotive batteries. Photorelays commonly used in battery systems must have a withstand voltage of approximately twice the system voltage, hence Toshiba’s new product is more than capable of servicing 400 V battery systems.
Improved charge times and a longer cruising range are essential for wider adoption of electric vehicles, and both require more efficient operation of battery systems. Battery management systems (BMS) realize efficient system operation by monitoring the battery charge status, plus the insulation between the battery and the vehicle body that is essential for the safe use of high-voltage batteries. In BMS that must handle high voltages, electrically insulated photorelays are used.
TLX9152M is housed in an SO16L-T package, widely used for high-voltage photorelays including Toshiba’s TLX9160T, which has an output withstand voltage of 1500V. Use of this package facilitates common circuit board pattern design.
