最近用到电磁式蜂鸣器,由于电源部分处理的不好,对电流的实时大小要有很明确的数值,平时用的万用表就派不上用场了,只好找了一款电流检测IC-Max471。
MAX471 是一款精密高端的电流检测放大器,在很多应用场景下都可以用的到,如电池/DC电源供电的系统中可以见到。
MAX471主要有一下特性:
© Complete High-Side Current Sensing
© Precision Internal Sense Resistor (MAX471)
© 2% Accuracy Over Temperature
© Monitors Both Charge and Discharge
© 3A Sense Capability with Internal Sense Resistor
(MAX471)
© Higher Current-Sense Capability with External
Sense Resistor (MAX472)
© 100µA Max Supply Current
© 18µA Max Shutdown Mode
© 3V to 36V Supply Operation
© 8-Pin DIP/SO Packages
下面直接就是典型应用电路:
