The BQ24160RGET from Texas Instruments is a battery charging solution that offers both high and low voltage charge termination. This device bridges the gaps between power management and battery management, making it an excellent choice for applications that require a single-stage charge solution. The BQ24160RGET has a wide range of applications, including those within the industrial, automation, medical and telecommunications industries. Additionally, it is suitable for production-level battery powered products such as radio frequency identification (RFID) tags, access control cards, and mobile phones.

The BQ24160RGET is a Power Management IC (PMIC) designed to charge rechargeable Li-Ion and Li-Polymer battery cells. It contains PowerPath technology which allows the device to operate as both a charger and power manager. The device monitors voltage levels and can automatically detect when battery charging is completed and then turn off charging. To accomplish this, the device features programmable charge current, voltage and timer limits. The device also provides various battery-protection features including overvoltage protection, overcurrent protection, thermal regulation and watchdog timer.

The BQ24160RGET also features Linearor Pulse-Width Modulation (PPM) charge mode selection. The Linear mode is suitable for low-power applications and the PPM mode is best for higher-power applications due to its ability to store and discharge current quickly. Additionally, the device has two independently programmable current limits. These make it ideal for applications with varying battery sizes and capacities. It also has a manual charging enable/disable pin, allowing manual override of the internal timer and current limit when manual control of the charging process is desired.

The BQ24160RGET can be used as both a stand-alone charger as well as a power management device when connected to an external battery. When used as a stand-alone charger, it offers both high-voltage and low-voltage termination mechanisms to meet the requirements of different rechargeable batteries and to provide an optimal charging profile. When used as a power manager, it enables the controller to shutdown supply voltage if the input voltage reaches a user-defined threshold. This prevents overcharge of the battery and minimizes energy wastage. Additionally, the device can provide thermal shutdown protection when used as a power manager.

In summary, the BQ24160RGET from Texas Instruments is a battery charging solution that bridges the gap between power management and battery management and provides a unique solution for applications that require single-stage charge. It offers a wide range of features and capabilities such as Linear or Pulse-Width modulation charge mode selection, two independently programmable current limits, overvoltage protection, and thermal regulation. Additionally, it is suitable for both stand-alone charge applications as well as power management applications. The BQ24160RGET is an excellent solution for industrial, automation, medical and telecommunications applications and production-level battery powered products.
