Working Principle of BQ24168RGER

The BQ24168RGER is a synchronous buck-boost adjustable voltage regulator, meaning it is able to regulate the power provided from either a higher or lower voltage input source. The N-Channel MOSFETs in the IC provide up to 8A of current at up to 12V output.The adjustable voltage and current allows for rapid charging of batteries. The output voltage and current can be adjusted to match the particular requirements of the battery being charged.The IC also contains a variety of safety features that enhance the safety and performance of your battery-operated devices. For example the IC can detect overcurrent, overvoltage, undervoltage, and over-temperature conditions and shut itself off to prevent damage to the device. This feature drastically increases the overall reliability of the BQ24168RGER as well as reducing the risk of inadvertently damaging any attached device.The IC can also work with an external temperature sensor to limit charging current if the battery temperature gets too high during charging. This prevents the battery from overheating, and reduces the risk of damage or even an explosion.The BQ24168RGER also provides a low-battery detection and an idle-mode to reduce power output if the battery is fully charged or if it is not in use. This reduces power consumption and increases the overall battery life.

Conclusion

The BQ24168RGER is an advanced, efficient and reliable dual-channel synchronous buck-boost adjustable voltage regulator from Texas Instruments. It is capable of efficiently and quickly charging rechargeable NiMH and Li-Ion batteries, and is suitable for applications such as smart phones and tablets, portable consumer electronics, and industrial equipment.The adjustable voltage and current, combined with the wide range of safety features, make the BQ24168RGER an ideal choice for anyone looking for a reliable power source for a battery-operated device.
