LINEAR TECHNOLOGY  LT8584EFE#PBF  芯片, 单片电池平衡器, TSSOP-16

The is a monolithic fly-back DC/DC Converter designed to actively balance high voltage stacks of batteries. The high efficiency of a switching regulator significantly increases the achievable balancing current while reducing heat generation. Active balancing also allows for capacity recovery in stacks of mismatched batteries, a feat unattainable with passive balance systems. In a typical system, greater than 99% of the total battery capacity can be recovered. The part runs completely off of the cell which it is discharging, removing the need for complicated biasing schemes commonly required for external power switches. The enable pin DIN of the part is designed to work seamlessly with the LTC680x family of battery stack voltage monitoring ICs. The LT8584 also provides system telemetry including current and temperature monitoring when used with the LTC680x family of parts.
