Reference Designs
USB Li-Ion Battery Charger and Power-Path Management Reference Design
Texas Instruments
This reference design delivers up to 1000 mA of continuous current to the battery output when programmed with a resistor on the ISET pin and is programmed at the factory for ~540mA. The USB current limit modes are selected by the ISET2 pin and limits current to a maximum of 500 mA (logic high) or 100 mA (float or high impedance). A low on the ISET2 pin programs the charge current using the ISET resistor.
