Description: Standalone Linear Li-Ion Battery Charger

Features

* include charge current monitor, under-voltage lockout, automatic recharge and a status pin to indicate charge termination and the presence of an input voltage
* FEATURE
* Programmable Charge Current Up to 500mA
* No MOSFET, Sense Resistor or Blocking Diode Required
* Complete Linear

Applications

* Furthermore, the UP4054A is specifically designed to work within USB power specifications. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature during high power op
