The MAX17302X+T, manufactured by Maxim Integrated, is a compact battery fuel gauge integrated circuit (IC) designed for monitoring lithium-ion or lithium polymer batteries. This device is housed in a small 15-pin wafer-level package (WLP) measuring 1.68x2.45 mm, which enables efficient space utilization in electronic devices. It features multiple protective functions such as over-current, over-temperature, over-voltage, and short circuit protection, ensuring the safe operation of battery systems. Communication with the device is facilitated via an I2C interface, allowing for easy integration and data exchange with other system components.
