LTC4162EUFD-FAD#PBF

LTC4162 is a 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 power path topology decouples the output voltage from the battery allowing a portable product to start up instantly under very low battery voltage conditions. It is used in application like medical instruments, USB-C power delivery, industrial handhelds, ruggedized notebooks, tablet computers etc.
