The LX2201 Linear Battery Charger is amulti-state (2 stage) Li-Ion battery charger (Constant current / Constant voltage) that can supply up to 2A of charging current into a single cell Li-Ion battery.

LX2201 is a cost effective , high performance USB battery charger. The LX 2201 features a 2A high charge current, with automatic power savings using isolated battery topology, user programmability in USB charging, and an extended battery life with low RdsON in discharge.

In USB mode, the LX2201 has advantages over competition chargers with the USB Limit Control circuit and low RdsON in discharge mode. The USB limit Control circuit allows simultaneous battery charging while the device is in operation. The VDD to supply load is independent of the VBAT charging logic. In discharge mode a low RdsON provides low loss and heavy transient.
