Evaluation and Demonstration Boards and Kits are a versatile way for people to quickly explore a particular technology and evaluate its performance. The BQ24103EVM application field and working principle offer an excellent option for users to quickly and effectively learn and experiment with the BQ24103-related applications.

The BQ24103EVM is a high-voltage, integrated Power Management and Battery Charging IC, which combines a power path management, a linear battery charger, and a DC/DC synchronous buck converter in a single chip. It provides a complete Power Management solution for systems running on rechargeable battery sources such as 6-cell Li-Ion/ Li-Polymer and 3-cell LiFePO4 chemistries while also providing a stable 5V output for digital loads. The BQ24103EVM application field and working principle enable fast, simple, and safe implementation of an advanced battery powered system.

The BQ24103EVM supports charge currents up to 3A and an input voltage range from 4.4V to 20V, with a wide input voltage range of 6V to 20V. Additionally, its integrated charger and power path provide maximum system flexibility, allowing the battery to remain permanently connected to the inputs while maintaining the host system powered from the input source. This feature prevents system reset when the input shuts down for only a few seconds. The highly accurate voltage regulation loop on the BQ24103EVM ensures output voltage regulation even during strong load transients.

The BQ24103EVM includes several protection features such as overvoltage protection, undervoltage lockout, reverse current, thermal protection, ultrasound shutdown and short circuit protection. Additionally, its standalone operating mode allows uninterrupted system operation when the inputs are disconnected from the system’s power source.

In terms of working principle, the BQ24103EVM is a single-chip solution that integrates a battery charger, a power path management, and a DC/DC synchronous buck converter in one device. Its working principle starts with the power path management, which works to control the power path between the battery and the loads. The device utilizes two charge modes - a trickle charge mode for light loads and a main charge mode for heavier loads. In addition, the charge current can be programmed up to 3A for fast charging. The device also includes an input voltage feature which allows the input voltage to be adjusted to support the required output voltage.

The BQ24103EVM also includes a synchronous buck converter for regulated 5V outputs. It includes a high efficiency switching regulator, with a low quiescent current that extends the system battery runtime. Additionally, the device also provides an adjustable output voltage range from 0.6V to 5V. The output voltage is adjustable over the full input voltage range, allowing the device to be used for a variety of battery powered products.

To make use of the BQ24103EVM application field and working principle, the device must first be connected to an external battery and input source. A software application is then used to configure the device for the desired parameters. Additionally, the user has the ability to monitor the device’s status using an LED. The LED shows the status of the device and the battery’s charging and/or discharging state.

The BQ24103EVM is an ideal solution for a wide range of battery-powered designs. Its integrated charger, power path management, and DC/DC synchronous buck converter provide system designers with tremendous flexibility in design and protection options. Its wide input voltage range and overvoltage protection allows it to operate in a variety of power environments. Additionally, its unique protection features provide the best solution for a wide range of applications.
