MAX17055为7μA低工作电流电量计，采用Maxim ModelGauge™ m5 EZ算法。ModelGauge m5 EZ不需要对特定电池特征进行建模，很容易实现电量计设计，并简化主机软件开发。ModelGauge m5 EZ提供可靠算法，对于绝大多数锂电池提供高精度测量。
ModelGauge m5 EZ算法既有库仑计出色的短期高精度、高线性度，又具备电压测量电量计的长期稳定性优势，温度补偿则提供了业内领先的计量精度保障。MAX17055自动补偿老化、温度和放电率，并提供精确的电量状态(SOC，%)和剩余电量(mAh)。当电池达到接近空电量的临界区域时，ModelGauge m5算法激活特殊的误差修正算法，进一步消除误差。器件提供三种方式报告电池寿命：容量的减少、电池电阻的增大和充电次数。
MAX17055提供精确的电流、电压和温度测量。使用内部温度测量或外部热敏电阻测量电池组的温度。通过2线I²C接口访问数据和控制寄存器。
MAX17055采用9引脚0.4mm焊距、1.4mm x 1.5mm的无铅微小尺寸WLP封装，以及2mm x 2.5mm、10引脚TDFN封装。

描述
The MAX32620FTHR board is a rapid development platform designed to help engineers quickly implement battery-optimized solutions with the MAX32620 Arm® Cortex®-M4 microcontroller with FPU. The board also includes the MAX77650 ultra-low power PMIC and MAX17055 fuel gauge to provide efficient power conversion and battery management with minimal board space. The form factor is a small 0.9in x 2.0in dual-row header footprint that is compatible with breadboards and off-theshelf peripheral expansion boards. In addition to the dualrow headers, there are also two 12-pin Pmod™-compatible socket connectors for more expansion options. Also on board are common user-interface peripherals including two RGB indicator LEDs and two pushbuttons. These provide a power-optimized flexible platform for quick proofs-of-concept and early software development to enhance time to market.
