BQ24230RGTR

Product Summary

The BQ24230RGTR is an USB-friendly lithium-ion battery charger and power-path management IC. The BQ24230RGTR operates from either a USB port or ac adapter and support 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 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. The applications of the BQ24230RGTR include Bluetooth Devices, Low-Power Handheld Devices.
