Evaluation and Demonstration Boards and Kits

The BQ24185EVM application field and working principle is a demonstration and evaluation board that assesses the performance of the current digital power management and battery charger device. This board is primarily used in applications where precise control over charge voltage, current and battery health is required. It utilizes a TI BQ24185 single-cell lithium ion (Li-ion) or LiPo battery charger, and TI bq24195A synchronous bimodal boost converter with integrated 3.3V power source. The board also features a Battery Management System (BMS) that simplifies the monitoring and protection of the battery and its components.

The board allows users to measure the charge current and the battery voltage, and adjust various charger parameters such as charge current and voltage. The EVM also has virtual sense resistor and adjustable parameters to customize the charge profile to best suit the application. The board includes a graphical user interface (GUI) for easy setup and programming of various charger parameters, and a pin-out adapter board for interfacing with a microcontroller.

The BQ24185EVM can be used in a variety of applications including automotive, industrial, consumer, medical, and telecom. In automotive applications it can be used to provide efficient, reliable charge management and protection for the battery. This board can also be used in industrial applications such as solar energy, wind energy, or battery storage, as well as consumer applications like laptop, cellular phones, tablets, and other battery powered devices. The BQ24185EVM is the ideal solution for those looking for a reliable, efficient, cost-effective, and easy-to-program charger.

The working principle of the BQ24185EVM is based on the TI bq24195A synchronous bimodal boost converter with integrated 3.3V power source. The board applies a step-up (boost) converter to increase the battery voltage to an optimum charge voltage. The board also has a regulation loop to ensure constant charge current regardless of the battery voltage. Finally, when the desired charge voltage is achieved, the board shuts down the step up converter and enters float charge mode, allowing the system to continue to monitor the battery.

The BQ24185EVM is a great combination of functionality and efficiency. It allows users to measure the charge current and the battery voltage, and adjust various charger parameters such as charge current and voltage. The board also provides a graphical user interface (GUI) for easy setup and programming of various charger parameters. Moreover, it features a virtual sense resistor and adjustable parameters for customizing the charge profile to best suit any application. This board is perfect for those looking for an efficient, reliable, and cost-effective charger.
