- 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
Charging 2-cell, 8.4-V battery packs from a legacy 5-V USB port requires a boost charger. The BQ25883 is a highly integrated 2-A boosting, 1.5-MHz switch-mode battery charge management with dynamic power-path management for 2-s Li-ion and Li-polymer batteries. The I2C serial interface with charging and cell balancing settings makes the device a truly flexible solution. OTG buck operation allows enables the input port to supply power from battery.
