LN2051
1A is compatible with the USB interface, linear battery management chip
■ General Description
The LN2051 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. LN2051 requires minimal external components, and meet the USB bus specification, is very suitable for portable applications in the field. Thermal modulation circuit can control the chip temperature in a safe range when the device power dissipation be relatively large or the ambient temperature be higher. Within a fixed constant charge voltage 4.2V, can al...
