Product Overview

The LT8584IFE#PBF 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.
  • No additional software required
  • Selectable current and temperature monitors
  • Ultralow quiescent current in shutdown
  • Can return charge to top of stack
  • Can return charge to any combination of cells in stack
  • Can return charge to 12V battery for alternator replacement
  • Can be paralleled for greater discharge capability
  • All quiescent current in operation taken from local cell
