bq24232HA USB Friendly 0.5A Li+ Charger Texas Instruments bq24232HA USB Friendly 0.5A Li+ Charger is a highly integrated Li-ion linear charger and system power path management device. This device is targeted at space-limited portable applications. The charger operates from either a USB port or AC adapter and supports charge currents between 25mA and 500mA. The high-input-voltage range with input overvoltage protection supports low-cost, unregulated adapters. The USB input current limit accuracy and start-up sequence allow the bq24232HA to meet USB-IF inrush current specifications. Additionally, the input dynamic power management prevents the charger from crashing poorly designed or incorrectly configured USB sources.
