We use an ADCMP350 comparator in a circuit and would like to provide extra protection to prevent damage in the case of overvoltage at the supply. We have a series resistor to limit current available to VCC, and a zener diode (Vz = 5.5V) to limit the voltage…
I have to supply rails: an adapter AC/DC and one USB. They are ORed together through diodes. I want to support 5V adapters (if it is connected the USB power is turned off) so if the voltage is greater than 4.5V on the adapter side I disable the USB power…
Hello All,
This is a elementary question but confusing one.
According to Figure 21(I attached below) in the ADCMP354 datasheet(Rev B), I think at fist comparator connect to n-FET and its drain connect to the output-pin, then if the output of comparator…
Chun,
you may be able to use a comparator powered by the battery such as the ADCMP350

you need to rectify the AC with a diode and capacitor and compare that…
Hello Everyone,
Im working on a battery charger circuit. I set completely the figure-22 and the figure-23 in the datasheet. So more than hundred try and later than weeks. The circuits are not working as expected. This part is important "The circuits are…
