Evaluation and Demonstration Boards and Kits are widely used for assessment and demonstration purposes in many applications. BQ24093EVM is an evaluation module from Texas Instruments that offers a comprehensive and integrated solution for power management in desktops, laptops, and wired/wireless communication systems. It is designed to provide a platform for engaging users in evaluation and design using the BQ24093 in a wide range of applications.

The BQ24093EVM is used to evaluate the features and performance of the BQ24093 low input voltage, high efficiency charger(LIHV). This charger is designed to provide fast, accurate charging capability for applications and also features linear regulation control, over-current protection, thermal balance control, and reverse power protection. The board features various input source connections which enable users to evaluate the solution in different power systems. It also features Cycle-by-Cycle Current Limit, a UC/UI Total Charge Timer, and a Universal I/O Header Connectors.

The working principle of BQ24093EVM is based on its system control scheme which is employed to regulate the output voltage and current accurately. The module utilizes an integrated Voltage Loop (IVL) to control the output voltage to the system. The IVL is activated by an internal comparator to monitor the output voltage. When the output voltage is above the setpoint, the output current is turned off to limit the output from reaching the maximum load output. When the output voltage is below the setpoint, the output current is increased allowing the system to reach the desired output voltage.

The BQ24093EVM also provides feedback control to the system, allowing it to adjust the output voltage and current waveforms according to the battery\'s charging needs. The module also utilizes an adaptive voltage control (AVC) to control the output voltage, and a charge current control (CCC) which allows for fast and accurate charging of the battery. The AVC and CCC also work together to extend the battery life and optimize the charging performance.

BQ24093EVM is ideal for charging systems in consumer, industrial and automotive applications, and is suitable for fast and accurate charging in a wide range of voltage inputs. It also provides an easy-to-use, flexible and scalable power management platform for both developers and users. The evaluation module is also ideal for development and testing as it offers full-featured design tools for the evaluation and optimization of the BQ24093.
