Evaluation and Demonstration Boards and Kits are designed to enable customers to evaluate and demonstrate Texas Instruments products. The BQ24296EVM-021 board is a tool used for accurate and efficient evaluation of the BQ24296 device. The key features of the BQ24296EVM-021 board include a 7-bit external I2C selectable current full-scale range of from 1.2A down to 0.1A, multiple selection of charge voltage, remote sense for better accuracy over long cable lengths, power switch control and status monitoring, system cell temperature sense, and six independent safety timers for charge safety.

This board is used in applications that are sensitive to very low current drift above the full-scale. It provides users with the widest selection of charge currents and voltages available in any stand-alone charger IC available today, and is well-suited for use in high-end portable audio, cellular phones, PDAs, etc.

The operating principle of the BQ24296EVM-021 board is quite simple. It consists of two main parts, the battery charger IC and the controller. The ASIC integrates a buck/boost complex power-conversion capability that is optimized for charging very low capacity batteries, in addition to load-sharing capability for multiple devices.

It is capable of delivering up to 1.2A of charging current to the battery. The controller acts as a regulating agent, monitoring the status of both the battery and the charging process. It has several safety mechanisms that regulate the operation of the device, such as an adjustable timer for overcharge protection, simultaneous thermal and voltage protection, and charge-current limiting.

The BQ24296EVM-021 board has several advantages over other battery-charging systems. One of the key benefits is its adjustable current limit, which allows users to customize the device for different battery packs. It also has a high-efficiency switch-mode charger, which reduces power dissipation. Furthermore, its safety features provide accurate thermal protection and voltage regulation. Finally, its wide variety of charging currents provides improved compatibility with different battery types.

In conclusion, the BQ24296EVM-021 board is a high-efficiency evaluation tool designed to accurately and efficiently evaluate the BQ24296 device. It offers several advantages, such as adjustable current limit, high-efficiency switch-mode charging, and safety features. It is the perfect tool for evaluating Texas Instruments products and is well-suited for use in high-end portable electronics.
