TI BQ24079QWRGTRQ1

锂离子/聚合物1.5A-40°C ~ 125°C（TA）

Overview

The BQ2407x series of devices are integrated Li-Ion linear chargers and system power pathmanagement devices targeted at space-limited portable applications. The devices operate from eithera USB port or an AC adapter and support charge currents up to 1.5 A. The input voltage range withinput overvoltage protection supports unregulated adapters. The USB input current limit accuracyand start up sequence allow the BQ2407x to meet USB-IF inrush current specifications. Additionally,the input dynamic power management (VIN-DPM) prevents the charger fromcrashing incorrectly configured USB sources.

The battery is charged in three phases: conditioning, constant current, and constantvoltage. In all charge phases, an internal control loop monitors the IC junction temperature andreduces the charge current if the internal temperature threshold is exceeded. The charger powerstage and charge current sense functions are fully integrated. The charger function has highaccuracy current and voltage regulation loops, charge status display, and charge termination. Theinput current limit and charge current are programmable using external resistors.
