电池脱离及冷复位开关

SGM4076为全新设计冷复位电池脱离开关。该电路用来保证装箱时电池处于近乎与负载脱离的状态，用于延长成品仓储时间，实现开盒即用、改善客户感受，方便壳体和包装的灵活设计。仅使用“开机”和“电源保持”信号配合即可实现电池脱离动作和电池开通动作。必要时还可以利用其电池脱离功能完成掉电重启循环。\n\n SGM4076具有热关断保护和较低的导通阻抗。\n\n SGM4076采用绿色环保WLCSP-1.31×1.62-12B和TDFN-3×3-8L封装，工作温度范围为-40℃至+85℃。 • WLCSP封装导通电阻：20mΩ（TYP）\n• 抗湿漏输入\n• 过热开路保护\n• 抗浪涌\n• 典型时间参数（可利用外置电阻选择不同值）  7.7s冷脱离延迟  1.9s开机延迟\n• 工作电压范围：1.6V ~ 5.5V\n• 最大连续工作电流：  4.5A（TDFN-3×3-8L封装）  6A（WLCSP-1.31×1.62-12B封装）\n• 唤醒输入符合ICE61000-4-2 L4要求\n• 采用WLCSP-1.31×1.62-12B和TDFN-3×3-8L绿色环保封装\n• ESD保护;
