DRV5015 是一款磁性传感器,具有数字输出,可锁存最近测量的极点。上电期间,如果没有外部磁场,DRV5015A1 和 DRV5015A2 默认为低输出状态,而 DRV5015A3 默认为高输出状态。在封装顶部附近施加南磁极会导致 DRV5015A1 和 DRV5015A2 输出驱动为低,而北磁极会导致此输出驱动为高。在封装顶部附近施加南磁极会导致 DRV5015A3 输出驱动为高,而北磁极会导致此输出驱动为低。没有磁场会导致输出继续驱动当前状态,无论是低还是高。

如果原发电源故障定期发生,或者将DRV安装在安全系统中,该供应系统至关重要,则必须至少每12个月更换一次电池,作为年度维护例程的一部分。在非关键系统中或电池使用率低,更长的替换周期最多可被视为最多5年。
