Introduction

The BQ25060EVM is a highly reliable, advanced, high-performance evaluation board and kit designed and developed by Texas Instruments. It is specifically designed to support the Texas Instruments BQ25060 power management chip, which is a versatile, high-performance battery charger IC capable of charging one or two lithium-ion batteries when powered by an AC adapter or USB charger. This board is ideal for a wide range of applications, from providing efficient and safe charging of batteries used in consumer electronics, to providing support for the evaluation and demonstration of advanced mobile and stationary battery applications. The BQ25060EVM board offers an easy-to-use platform for evaluating and demonstrating the capabilities of the BQ25060 power management chip.

Design and Features

The BQ25060EVM-K evaluation board integrates the BQ25060 single-cell Li-Ion battery charger IC. The board’s features include an adjustable power input of 5V to 18V, a high accuracy Voltage Output (VIN-VOUT) of 1V to 7V with settings of 0.3V or 0.1V, and a capable VCharge current up to 2.1A. The board also includes enable pins for selecting the appropriate mode of operation (automatic charge, manual charge and idle mode). In addition, it has a boost switch and a status LED for power on and charge complete status indication.

Applications

The BQ25060EVM is ideal for a wide range of applications, including the powering of mobile phones, tablets, MP3 players, digital cameras, game consoles, and other portable electronic devices. It enables the safe and efficient charging of one or two Li-Ion batteries. It can also be used for various stationary and mobile applications such as providing support for energy management, battery monitoring, power monitoring, and energy harvesting.

Working Principle

The BQ25060 chip, at the heart of the BQ25060EVM board, is a highly efficient, integrated power management chip, capable of charging Li-Ion batteries from an AC adapter or USB charger. The chip operates in three different modes: Automatic Mode (A-Mode), Manual Mode (M-Mode), and Idle Mode. In A-Mode, the device automatically switches to the appropriate regulation current and to a trickle charge when the battery is nearly full. In M-Mode, the user can manually select the appropriate current limit and charging termination voltage settings. In Idle mode, the chip automatically releases the system power and will allow the system to enter low-power mode. The BQ25060 chip provides monitoring features such as over-temperature protection, over-current protection, and switching frequency adjustment to ensure safe and efficient charging of the battery.

Conclusion

The BQ25060EVM is an advanced, high-performance evaluation board and kit specifically designed for evaluation and demonstration of the BQ25060 power management chip. It is ideal for a wide range of applications, from efficient and safe charging of Li-Ion batteries used in consumer electronics, to providing support for energy management, battery monitoring, power monitoring, and energy harvesting. The BQ25060EVM offers an easy-to-use platform for evaluating and demonstrating the capabilities of the BQ25060 power management chip.
