内置ModelGauge m5 EZ的7µA单节电池电量计

业界IQ最低的电量计,采用ModelGauge m5 EZ算法,无需电池建模

产品详情

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。

设计方案:正确的电池电量计助您实现最快上市时间和最长工作时间

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.
