【应用】国产低功耗复位芯片SGM809B用于以太网交换机,可满足3V,3.3V和5V的电源监控
现在随着数据中心的发展,传输速率越来越快,需要承接的传输设备越来越多,对于交换机的需求也是日益增长了。随着传输速率的提升,千兆以太网卡、万兆网卡,甚至还有很多超万兆的网卡出现,以太网交换机中微处理器的电源监控以及复位就至关重要。这里推荐圣邦微SGM809B复位芯片用于处理器电压的监控,在微处理器下电时进行复位输出,上电时将保持复位状态,最少保持150ms时间,直至系统稳定。
SGM809B的特点如下:
1、低功耗。300nA(TYP)工作电流,能满足交换机低功耗的需求。
2、多种监控电压的选择。阈值电压可设置为4.38、4.00、3.08、2.93、2.63V,满足3V,3.3V和5V的电源监控。
3、主动低电平复位,支持最低150ms延时复位信号,并支持推挽输出。
4、宽工作温度范围,-40~125℃的工作温度范围支持工业级的应用场景。
综上所述,SGM809B是一款低功耗、多种监控电压可选,支持150ms延时低电平复位的复位芯片,是以太网交换机中微处理器监控芯片的理想之选。

【应用】 圣邦微复位芯片SGM803在MCU电源电压监控中的应用,超低功率损耗13μA
MCU电源系统的稳定影响着MCU处理数据的稳定性,MCU工作可能发生混乱,导致程序跑飞,引起整机死机、误动作等现象,复位芯片的工作原理是通过确定的电压阈值启动复位操作,圣邦微(SGMICRO)SGM803有七个复位阈值电压可供选择。
【产品】具有电压检测功能的国产微处理器复位芯片MAX811X系列,2μA低功耗,宽工作电压1~6V
华冠半导体推出的MAX811X系列是一款具有电压检测功能的微处理器复位芯片,它带有使能控制端,用于监控微控制器或其他逻辑系统的电源电压。 它可以在上电掉电和节电情况下,或在电源电压低于预设的检测电压 Vth时,向系统提供复位信号。
【产品】微处理器监控IC R5106N内置延迟电路和看门狗定时器,检测精度高达±1.0%
Nisshinbo (日清纺) 推出的R5106N是一款微处理器监控IC,内部集成有高精度和超低功耗的电流电压检测器,内置延迟电路和看门狗定时器。检测器阈值在芯片内部恒定不变,检测精度高达±1.0%。
【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,受疫情影响,交货周期长,需要一颗国产替代料,本文重点推荐国产SGMICRO复位ICSGM811B-SXKA4G/TR,可PIN-TO-PIN替代,待机电流更低。
【应用】具有手动重置功能的复位芯片SGM811-SXKA4TR用于RCU主控电源监控,适用监控电压为3V
在RCU中主控占据着重要地位,它需要控制电机的转动,监控天线的倾斜角度,因此MCU供电电源的稳定很重要。本文推荐采用SGMICRO推出的监控MCU 3V电压源的复位IC SGM811-SXKA4TR,它在MCU加电、和断电情况下提供重置输出。
