Charger 6 Click Mikroe Charger 6 Click is a single-cell battery charger that features the Texas Instruments BQ25601 I2C controlled battery charger. It's used for high input voltage and narrow voltage DC power path management. It supports USB and is optimized for USB voltage input. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, and extends battery life during discharge. It also has a programmable current limiting, allowing it to use an external power supply rated up to 13.5V.
