Battery Management


Toshiba provides MOSFETs, diodes, photocouplers and other devices necessary for battery management.
Toshiba’s MOSFET portfolio includes both P- and N-channel devices with high quality and reliability suitable for use in lithium-ion battery protection circuits.
The U-MOSIX-H series fabricated with the latest low-voltage UMOS process features low conduction losses and therefore helps improve battery life.
Toshiba’s photocoupler portfolio includes photorelays for detection of short-to-ground faults and logic-output photocouplers for high-speed communication applications. These devices help reduce the power consumption and improve the reliability of battery management systems.
