LTC4162EUFD-LAD#PBF

LTC4162-L 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 rechargeable lithium-ion/polymer 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 I2C port. I2C port can also be used to configure many charging parameters including charging voltages and currents, termination algorithms and numerous system status alerts. It can charge Lithium-Ion cell stacks from 1 to 8 cells with as much as 3.2A of charge current. Power path topology decouples output voltage from battery allowing a portable product to start-up instantly under very low battery voltage conditions. Applications include medical instruments, USB-C power delivery, industrial handhelds, ruggedized notebooks and tablet computers.
