BQ24271YFFT 描述

***as Instruments: 1-cell, 1.5-A, I2C controlled buck battery charger with Power Path management 49-DSBGA -40 to 85

***ical: Switching Battery Charger Li-Ion/Li-Pol 1500mA 49-Pin DSBGA T/R

***i-Key: IC BATT CHG LI-ION 1CELL 49DSBGA

***NS: The bq24270 and bq24271 are highly integrated single cell Li-Ion battery charger and system power path management devices targeted for space-limited, portable applications with high capacity batteries. The single cell charger has several input current limits which allow operation from either a USB port or higher power input supply (i.e. AC adapter or wireless charging input) for a versatile solution.

***AS INSTR: The power path management feature allows the bq24270 and bq24271 to power the system from a high efficiency DC to DC converter while simultaneously and independently charging the battery. The charger monitors the battery current at all times and reduces the charge current when the system load requires current above the input current limit. This allows for proper charge termination and timer operation. The system voltage is regulated to the battery voltage but will not drop below 3.5 V. This minimum system voltage support enables the system to run with a defective or absent battery pack and enables instant system turn-on even with a totally discharged battery or no battery. The power-path management architecture also permits the battery to supplement the system current requirements when the adapter cannot deliver the peak system currents. This enables the use of a smaller adapter. The charge parameters are programmable using the I2C interface

***: The battery is charged in three phases: precharge, fast charge constant current and constant voltage. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if the internal temperature threshold is exceeded. Additionally, a voltage-based battery pack thermistor monitoring input (TS) is included that monitors battery temperature for safe charging The TS function for bq24270 and bq24271 are JEITA compatible.
