The HL7061 is a fully integrated boost mode 2/3S Li-ion battery charger with integrated power MOSFET, I²C interface and buck-discharge function. It can be used with 2/3 series Li-ion and Li-polymer batteries in a wide range of laptops, tablets, power banks, and other portable devices. Its switch-mode operation and low-resistance power path maximize charging, discharging, and buck efficiency. It also reduces battery charging time and extends battery life during a discharging phase.

This device supports a wide range of input sources, including standard USB host port, USB charging port, and high-power AC-DC adapter. It supports an input operating voltage from 3.9V to 14V. It can automatically adjust to the maximum power output of the input source via the input dynamic power management control (VUSBDPM).
