BQ24090 Single Input, Single Cell Li-Ion and Li-Pol Linear Battery Charger Evaluation Module



Texas Instruments  BQ24090EVM

The user’s guide for BQ24090EVM describes the bq24090 evaluation module (EVM), how to perform a stand-alone evaluation or interface with a host or system. The charger is designed to deliver up to 1000mA 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 500mA (logic high) or 100mA (float or high impedance). A low on the ISET2 pin programs the charge current using the ISET resistor.
