BQ24232RGTR Description

The BQ24232RGTR is a highly integrated Li-ion linear charger and system power-path management device targeted at space-limited portable applications. The BQ24232RGTR operates from either a USB port or ac adapter and supports charge currents between 25 mA and 500 mA. 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 bq2423x to meet USB-IF inrush current specification. Additionally, the input dynamic power management (VIN-DPM) prevents the charger from crashing poorly designed or incorrectly configured USB sources.
