Battery Cell Balancers

Analog Devices battery cell balancer portfolio includes fault-protected controller ICs for transformer-based, bidirectional active balancing of multicell battery stacks, as well as monolithic flyback dc-to-dc converters designed to actively balance high voltage stacks of batteries. Our devices include unique, level-shifting SPI-compatible serial interfaces, with active balancing that allows for capacitive recovery in stacks of mismatched batteries—a feat unattainable with passive balance systems.
