Please contact each Web shop for details such as availability of online samples.


The S-5471 Series, developed by using CMOS technology, is a voltage monitoring IC with an ultra-low current consumption.
Since the feed-through current in the IC is extremely low, the error can be reduced when the voltage of a power supply with high impedance is detected.
In addition, since the detection voltage is extremely low, a tiny amount of power generated by energy harvesting can also be detected.
Due to its ultra-low current consumption and low-voltage operation, the S-5471 Series is suitable for battery-operated small mobile devices.
