Battery chargers are essential for devices powered by rechargeable batteries. Compared with single-cell battery charger, Texas Instruments’ BQ24079TRGTR multi-cell Li-Ion battery charger, which supports one to four cells, is designed to offer higher versatility, higher efficiency and higher current performance. Furthermore, Its integrated power path management provides the best solution for fast charging, safety and quick system powerup.

The application field of BQ24079TRGTR is mainly aimed at consuming products powered by rechargeable Li-Ion batteries such as: portable radios, CD players, audio products, notebook computers, tablet PCs, mobile phones, secondary and portable battery powered products, etc.

BQ24079TRGTR can regulate the current and the voltage for multiple cells through two phases. Firstly, when Vbus is lower than 4.35V, it is in precharge mode in which some current (Ipredrive) will be distributed to every cell for pre-charging. Secondly, when Vbus is higher than 4.35V, it is in parallel regulation mode in which the current is reduced from 0.3~3A decided by SEL pin.

In addition, the integrated 7-bit ADC is there to read back input voltage between the range of 4V to 26V, battery voltage between 0V and 5.5V and NTC voltage between 0V and 4V.

What’s more, BQ24079TRGTR is equipped with set of advanced safety features such as Over Voltage Protection (OVP), Input Over Voltage Protection (IOVP), Under Voltage Protection (UVP), Over Temperature Protection (OTP) and Charge Time Limit.

To conclude, BQ24079TRGTR is an ideal choice for those rechargeable products with advanced charge management and complete safety protections.
