Industrial & Consumer BMS

Intersil's li-ion battery pack monitoring, protection and balancing ICs are specifically designed to meet the stringent safety, reliability and performance requirements of portable and battery powered applications such as consumer products, home appliances, battery backup and e-bikes.

Intersil's BMS ICs incorporate built-in fault detection for all major internal functions. They detect external faults such as open wire and over/under voltage, as well as temperature and cell balancing faults to mitigate battery pack failures. Overall the highly integrated functionality of the ISL94202, ISL94203, ISL94208 and ISL94212 offer a number of benefits and their use can significantly reduce overall battery management costs.

We also offer digital power monitors for 1 to 2 cell solutions and automotive-grade BMS.
