Evaluation and Demonstration Boards and Kits provide powerful tools for the design and development of a wide range of electronic systems. One key component of such kits is the BQ24750AEVM. This device allows for the easy evaluation and testing of the performance of the BQ24750A Charge Pump Controller. This article will introduce the application fields and working principle of BQ24750AEVM.

The BQ24750A is a Charge Pump Controller based on BQChip Technology. It is a single chip device designed to manage the charging of mobile devices such as smartphones and tablets. It offers a range of protections such as overvoltage protection, overcharge protection, and over-discharge protection. It can also support up to 25W of charging power and has a wide input voltage range (3.0V to 5.5V).

The BQ24750AEVM allows for easy evaluation of the performance of the BQ24750A and is designed to be used with other evaluation modules such as the high voltage modules. The EVM includes the BQ24750A, an LDO voltage regulator, an inductor, an SPI interface, and a USB micro B connector for programming. It can be powered conveniently through the USB port or through the LDO voltage regulators. It also includes several terminal pins and jumpers for connecting external components.

Product applications of the BQ24750AEVM are mainly in the field of mobile product charging. It is also widely used in other mobile device applications such as tablet PCs, camera batteries, and navigation systems. The BQ24750AEVM can also be used for debugging and testing purposes.
