BQ24091EVM概述
Evaluation Module For Single-Input, Single-Cell Li-Ion Battery Charger
The user’s guide for describes the bq24091 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.
