LN2052 - natlinear

LN2052 1A Is Compatible With The USB Interface / Linear Battery Management Chip

The LN2052 is a constant- current / constant- voltage charger circuit for single cell lithium-ion batteries. The device includes an internal power transistor, does not need external current sense resistor and blocking diode in applications. LN2052 requires minimal external components, and meet the USB bus specification, is very suitable for portable applicat.

Features

include low input voltage latch, automatic recharge, the battery temperature monitoring and charge status / charge status indication functions.LN2052 uses thermally enhanced 8-pin small outline package SOP-8/PP or MSOP-8/PP.
