BATT-MON 5 Click is based on the LC709204V, a 1-cell Lithium-ion/Polymer (Li+) battery fuel gauge from onsemi. This highly efficient fuel gauge monitors battery performance with exceptional accuracy and stability while consuming minimal power, making it a perfect solution for modern portable and battery-powered devices. The LC709204V uses the innovative HG-CVR2 algorithm, a proprietary technology that accurately determines a battery's Relative State of Charge (RSOC). This algorithm ensures reliable RSOC readings even under varying and challenging conditions such as fluctuating temperatures, different load demands, aging of the battery, and self-discharge rates. With precise RSOC measurement, the LC709204V optimizes battery usage, extending the operating time of devices like wearables, PDAs, USB-related systems, and configurations such as 1-series N-parallel battery systems.
One of the standout features of the LC709204V is its ease of integration. To begin operation, the HG-CVR2 algorithm requires only a few simple parameter configurations upon battery insertion. This significantly reduces development complexity and allows for rapid deployment in various applications. In addition, the device offers State of Health (SOH) reporting, giving insights into the overall condition and longevity of the battery.
This Click board™ is designed in a unique format supporting the newly introduced MIKROE feature called "Click Snap." Unlike the standardized version of Click boards, this feature allows the main IC area to become movable by breaking the PCB, opening up many new possibilities for implementation. Thanks to the Snap feature, the LC709204V can operate autonomously by accessing its signals directly on the pins marked 1-8. Additionally, the Snap part includes a specified and fixed screw hole position, enabling users to secure the Snap board in their desired location.
BATT-MON 5 Click communicates with the host MCU via a standard I2C interface, supporting clock speeds of up to 400kHz for fast and efficient data exchange. To ensure safety and reliability, the board includes an alert interrupt (ALR) pin, activated whenever critical conditions are detected, such as low cell voltage, abnormal temperature, or low Relative State of Charge (RSOC). This integrated alarm functionality provides timely alerts to users, helping to prevent potential issues like over-discharge or unsafe operating conditions, thereby enhancing overall battery safety.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
Click Snap is an innovative feature of our standardized Click add-on boards, introducing a new level of flexibility and ease of use. This feature allows for easy detachment of the main sensor area by simply snapping the PCB along designated lines, enabling various implementation possibilities.
