Product Summary

The BQ24022DRCR is an integrated Li-ion linear charger and system power path management device targeted at space-limited portable applications. The BQ24022DRCR operates from either a USB port or AC adapter and support charge currents up to 1.5A. The input voltage range with input overvoltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the BQ24022DRCR to meet USB-IF inrush current specification. Additionally, the input dynamic power management (V IN -DPM) prevents the charger from crashing incorrectly configured USB sources. The applications of the BQ24022DRCR include Smart Phones, Portable Media Players, Portable Navigation Devices and Low-Power Handheld Devices.
