低成本、2线电池监测器，提供比例A/D输入

DS2746依旧在生产中，假如您正准备开发新产品，我们推荐ModelGauge m5 MAX17055电量计。\n\n DS2746可为成本敏感应用提供系统侧电池电量监测。通过2线接口将电压、双向电流及累积电流测量数据提供给主处理机。失调偏置和失调消隐特性可以极大的提高库仑计的精度。另外，DS2746有两个辅助A/D输入，可用来采样电池包识别电阻、热敏电阻或其他电压源。转换结果是一个与电源电压成比例的小数，这可以消灭与电源有关的误差。DS2746通过VOUT引脚使能电阻分压器，使之仅在进行测量时工作，以减小测量电路的总功耗。当系统不活动时，低功耗休眠模式可以减少电流消耗，同时保持库仑 • 14位双向电流检测\n• ±51.2mV动态范围时，LSB为6.25µV\n• ±3.4A动态范围(RSNS = 15mΩ)时，LSB为416.7µA\n\n\n• 电流累积寄存器分辩率\n• 409.6mVh范围时，LSB为6.25µVhr\n• 27.31Ah范围时，LSB为417µAhr\n\n\n• 11位电池电压检测\n• 0V至4.997V输入电压时，LSB为2.44mV\n• 3.6V输入时精度为±10mV\n\n\n• 2个11位Aux输入电压测量\n• 比例输入可消除电源带来的误差\n• VOUT驱动分压器，可降低功耗\n• ±8 LSB精度 \n\n\n• 低功耗：\n;
