【选型】国产复位IC SGM811B-SXKA4GTR可替代安森美CAT811STBI用于小基站，待机电流更低
某客户小基站项目上有使用到一颗安森美的复位芯片CAT811STBI，来监控MCU的工作。受到国际疫情的影响，交货周期日益拉长，从而需要寻找一颗国产的替代料，本文将重点推荐国产圣邦微（SGMICRO）的复位IC SGM811B-SXKA4G/TR，可PIN-TO-PIN替代CAT811STBI。
图1：SGM811B-SXKA4G/TR与CAT811STBI的参数对比
从图1所示的参数对比表可以看出：
1、从工作电压范围、复位阈值电压、是否具有手动复位功能等分析，两者参数基本一致。
2、SGM811B-SXKA4G/TR的待机电流只有不到1μA，远远比CAT811STBI的8μA要小，说明SGM811B-SXKA4G/TR的待机性能要比CAT811STBI更加优秀。
3、从复位阈值的温漂上分析，SGM811B-SXKA4G/TR在全温度范围内的精度要更高。
图2：SGM811B-SXKA4G/TR与CAT811STBI的典型应用对比图
图3：SGM811B-SXKA4G/TR与CAT811STBI的封装对比图
图2和图3是SGM811B-SXKA4G/TR与CAT811STBI的封装PIN脚及典型应用图，分析可知，两者的封装PIN脚和典型应用电路完全相同，所以SGM811B-SXKA4G/TR和CAT811STBI可以PIN-TO-PIN替换，可以大大缩短客户的替换验证时间，提升产品替换验证效率。并且，SGM811B-SXKA4G/TR属于国产物料，可以给客户提供更好的价格和交期。

你好，我们有用到ADI品牌的 LT8301ES5和ROHM的BD4840FVE-TR的IC,我们现在想找国产IC可以替代的，性能一致就可以，是否有推荐的国产品牌可以替代呢？
推荐圣邦微隔离电源芯片SGM46000（替代LT8301ES5）和复位芯片SGM706-J（替代BD4840FVE-TR），均为功能性替代，相关技术资料参考链接：SGMicro（圣邦微） SGM46000 3W主变压器和用于隔离电源H桥驱动器数据手册SGMicro（圣邦微）SGM706 Low-Cost, Microprocessor Supervisory Circuit
【应用】国产复位芯片助力基站天线RCU单元，支持手动复位，复位持续时间可达240ms
RCU由驱动马达、控制电路与传动机构构成。其中，主控电路供电稳定尤为重要，SGM811-SXKA4/TR复位芯片可监测电压包括1.8V/2.5V/3V/3.3V/5V，即使供电电压低至1V时也可保证复位有效性，因此可以应用于控制电路的主控。
求推荐两款性价比高的逻辑IC和复位IC；用来替代NXP品牌74HC08D SO14和ADI品牌ADM803 SC-70-3， 代加工项目：汽车IO扩展板 用于汽车驱动上；目前选型阶段；预计量产日期2019年四五月份；预计年用量100K以上
圣邦微有单与逻辑门SGM7SZ08， 罗姆这边也有：BU4S81G2。复位芯片圣邦微也有SGM803
【应用】圣邦微单双输入异或门SGM7SZ86YN5G/TR用于充电桩主控复位，输出电流达50mA
针对充电桩项目的复位，本文推荐圣邦微单双输入异或门SGM7SZ86YN5G/TR，输出电流可达50mA，静电等级为8000V，工作电压范围1.65V~5.5V，工作温度-65℃~150℃。
