【经验】微控制器监控芯片SGM812可以pin to pin替代CAT824,静态工作电流典型值13uA
一般控制芯片都需要稳定可靠的电源供电,一旦供电不正常,控制芯片就无法正常工作。因此控制芯片一般需要监控电路来实时监测其供电电压,一旦发现电压不正常就会关断或者重启主控制器,以免造成程序跑飞,造成不必要的损坏。因此在控制器的电源系统中,一款适合用于微控制器及数字系统供电电压监测的芯片必不可少。
图1 微控制器监控电路原理图
SGM812是圣邦微推出的微控制器监控芯片,可支持手动复位输入,可在上电、断电及掉电情况下产生复位信号,适合用于微控制器及数字系统供电电压监测。本文将介绍圣邦微公司推出的微控制器监控芯片SGM812,可完美与ON公司的CAT824做替代,而且噪声更低,精度更高,其性能参数对照表如下表所示。
图2 微控制器监控芯片SGM812和CAT824参数对比图
通过微控制器监控芯片SGM812和CAT824的比较可以得出:
1、供电参数上比较:微控制器监控芯片SGM812相比较CAT824来说,两者供电电压范围一致,但SGM812的监控电压范围更广,说明其能够适用于更过的芯片电压场合,可以完全替代CAT824使用,而且供电参数更优。
2、性能参数上比较:微控制器监控芯片SGM812相比较CAT824来说,SGM812的复位时间短,工作电流小,能够消耗更小的功率,发热量减小,能够更好的适应环境温度变化。
3、环境参数上比较:微控制器监控芯片SGM812相比较CAT824具有很大的温度优势,其能够在-40 ~ 125℃的环境温度下工作,适应恶劣环境温度能力强,能够更好的满足客户的要求。
通过供电参数、性能参数、环境参数对比分析可见,SGMICRO公司的微控制器监控芯片SGM812性能更加优越,在芯片电压监控上能够更好的发挥其作用。其次介绍下微控制器监控电路SGM812的引脚和封装尺寸,和CAT824一样,都包含标准封装SOT-23-5,封装尺寸完全兼容。
图3微控制器监控芯片SGM812和CAT824封装尺寸对比图
通过SGMICRO公司的微控制器监控芯片SGM812和CAT824的供电参数、性能参数、环境参数以及引脚封装尺寸对比,可以看出两者尺寸完全兼容可以pin to pin互换,而且微控制器监控电路SGM812在供电参数和性能参数上更具优势。
