The BQ24007PWP is part of Texas Instrument’s battery charger lineup and is a great choice for those who need a high-efficiency battery charging solution. This small power management integrated circuit (PMIC) is an integrated Li-Ion and Li-Polymer battery charger with an output current of up to 1.5A and an output voltage of 4.2V. The BQ24007PWP is available in a 5-term package and a high-temp version of the device comes with an extended operating temperature range up to 150° C.

The versatile BQ24007PWP can be applied in a variety of applications such as wireless headsets, cellular phones, medical device battery packs, and portable gaming consoles. The device features over-voltage, over-current, and over-temperature protection, as well as optional charge termination for two-cell Li-Ion batteries. This chip is capable of being used as either a standalone charger, or it can be controlled by a microcontroller or other system device using the BQ24007 communication interface.

The working principle of the BQ24007PWP is fairly simple. When the device is provided power, it starts charging the connected battery at a constant voltage of 4.2V. The current is allowed to flow until the battery has reached the configured termination voltage (usually 4.1V). Once the battery has reached the configured termination voltage, the charge cycle is complete and the BQ24007PWP will then switch to the idle state. Additionally, if any of the protections enabled while the battery is being charged activates, the device will enter the safety state.

In conclusion, the BQ24007PWP is an efficient charging solution that is suitable for a variety of applications. With its over-voltage, over-current, and over-temperature protection, as well as charge termination for two-cell Li-Ion batteries, this powerful PMIC can handle charging duties for Li-Ion and Li-Polymer batteries with confidence. Its simple working principle ensures that the device will work as expected, and its 5-term package makes it perfect for applications with a tight space constraint.
