bq24232 Overview
The bq2423x series of devices are highly integrated Li-ion linear chargers and system power-path management devices targeted at space-limited portable applications. The devices operate from either a USB port or ac adapter and support charge currents between 25 mA and 500 mA. The high-inputvoltage range with input overvoltage protection supports low-cost, unregulated adapters.
