General Description：单节开关式锂电池充电IC，内置MOS，充电电流可达1.5A，TDFN-10极小封装。
The TP8052 is a complete switching battery charger for one (4.2V) cell lithium-ion battery. The TP8052 provides a small, simple and efficient solution to fast charge Li-ion battery. An external sense resistor sets the charge current with high accuracy. 1A充电IC 1.2A充电IC  1.5A锂电池充电IC  单节PWM开关式锂电池充电IC

The maximum charge current which programmed by a resistor is up to 1.5A. An internal resistor divider and recision reference set the final float voltage to 4.2V. When the input supply is removed, the TP8052 automatically enters a low current sleep mode. 
The TP8052 is available in the 10-Lead TDFN package.
