Automotive Battery Management Systems (BMS)

Automotive Battery Management Systems (BMS) must be able to meet critical features such as voltage, temperature and current monitoring, battery State of Charge (SoC), and cell balancing of Lithium-ion (Li-ion) batteries. Therefore, selecting the right Electrostatic Discharge (ESD) protection device is topic of utter importance and needs special attention. Semtech provides a wide portfolio of robust ESD protection devices to protect the different commination interfaces of a BMS.
