ADI LTC4162IUFD-FAD#PBF

The LTC4162-F is an advanced monolithic synchronous step-down switching battery charger and PowerPath manager that seamlessly manages power distribution between input sources such as wall adapters, backplanes, solar panels, etc., and a rechargeable lithium iron phosphate battery. A high resolution measurement system provides extensive telemetry information for circuit voltages, currents, battery resistance and temperature which can all be read back over the I²C port. The I²C port can also be used to configure many charging parameters including charging voltages and currents, termination algorithms and numerous system status alerts. The LTC4162-F can charge LiFePO4 cell stacks from 1 cell to 9 cells with as much as 3.2A of charge current. The power path topology decouples the output voltage from the battery allowing a portable product to start up instantly under very low battery voltage conditions.
