BQ25886EVM 的特色
- Easily evaluate the high-efficiency 2-A, 1.5-MHz integrated field-effect-transistor (FET), switch-mode
- Power path management allows instant-on, works with no battery or deeply discharged battery
- Onboard USB input adapter for connecting to USB source and communication using the D+/D- function to set default input current limit
- Onboard test points, sense resistors, and jumpers facilitate measurement of high-efficiency- and high accuracy voltage and current regulation
BQ25886EVM 的說明
A charging 2-cell, 8.4-V battery from a legacy 5-V USB port requires a boost charger. The BQ25886 evaluation module (EVM) is used for the BQ25886, a highly integrated 2-A boosting, 1.5-MHz switch-mode battery charge management with power path for 2s Li-Ion and Li-polymer battery. The standalone feature sets all the charging parameters by external resistors. OTG buck operation allows enables the input port to supply power from battery.
