说明

MAX20094/MAX20095 IC集成了可配置恒流/恒压(CC/CV)电池充电器和高效同步升压控制器,在主电源断电时为关键系统供电。此外,提供诊断功能,用于检查电池的健康状态(SOH)和IC功能。可配置充电门限和输出电压,以支持主流化学成分电池和多节电池数量。为支持系统集成,IC提供I2C从机接口,通过该接口可访问配置、状态寄存器。

2.2MHz开关频率有助于大幅减小电感尺寸,降低系统成本。IC包括高精度SOH检查等内置功能,最大程度降低备份电池(BUB)的漏电流。

MAX20094/MAX20095采用28引脚(5mm x 5mm)侧面防潮TQFN封装,经过AECQ-100认证。
