3 Description
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. 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.
