1. What is the power supply for your IC? Is it the same battery whose voltage you are measuring? If so then you may not be able get correct readings. 2. To measure AC ripple riding a DC component, put in a series capacitor to block the DC. Then amplify the AC which comes through.
Hello everyone, I need to make 24 to 48 volts; 3 amp maximum from a 12 volt battery. Variable frequency Thanks for helping up you cannot design a circuit without specs. What exact device or output impedance vs frequency and V(t) supposed to look like. e.g. rise time, PW50 pulse width, tail time? What does I(
I'm looking for a way to convert TTL level digital(Can be PWM too) signals to 0-12 or 0-24 volt logic signals... The high level for the signals can vary from 9 volt to 32 volts. The circuit should be capable of sourcing a current of upto 50-100mA and sink the same... It should be protected against short to bat as well as short to ground condition
The logic is Marx circuit, voltage multiplier circuit... This can be found in Mosquito Killer bat circuit... If you go for mosquito killer bat and a Flyback Transformer it will cheaper and higher voltage than this.... Refer this
My government put lavacide in storm drains and ponds and now the mosquitoes (and bats that ate them) are gone. The larvacide does not harm birds, bees or animals. Modern technology is wonderful.
It's not clear what are PACK-, bat-, CHG-, and how you want the current pathes to be switched.
hare is dis. circuit for 3.6v lion bat. modifi for your need.77074
From looking at the lower image, the red/black wires should be "bat" and "bat-", for "battery" and "battery, Negative terminal". I believe P23 corresponds to a pin or via near the IC in the center of the board (under the ball of black potting material). I'm not sure what voltages are present on your speaker/microphone (...)
hi. I need circuit diagram for mobile battery charger, model no. JT-B50500 or JT-USB07, REV. 1.0
The absolute minimum voltage on any pin is -0.5V, so I think you should consider Schottky diode, like bat-85, configured as follows: The cathode of the diode is connected to the pin; Its anode is connected to GND .. see attached picture .. IanP :|
Hi, I think you need only a +/-5V supply for the Op= its done! K. Added after 5 minutes: These becouse DAC8831 has self an voltage output between 0V & Vref! With the OpAmp as a buffer only you have it repeated/amplfied, bat if the OpAmp is connected into your circuit (with DACs onchip resistors); control
Hi all. Can anybody help me to repair my mosquito killer bat . These bats works properly 2-5 days in new condition. But after then, these can't fry mosquitoes. I found that there is voltage in it's output terminal but not so high to fry(spark). Can anybody say wht's the problem?
HI You can use LTC4412 IC from linear tech. for ORing internal bat with external battery if power consumption is important - if it is not important you can use 2 diode.. All the best Bobi The microcontroller specialist
Dear Darla Look at microchip,Atmel and NXP site they have application note for programmable battery chrger: you will find code, circuit diagram, and explanation for how the circuit works All the best Bobi
Thanks for replay, I solved the problem. I have got an idea from an expert and this is worked fine for me. The capacitor based charging is possible for high current bat. The circuit diagram below I used and this method charge the 120Amp bat approximately in 5 Hr. I must say what I think about this design.. It's very ea
Modify an electric fly bat! Kills fly, wont kill you! Try it for your self! Try to hurt yourself first before try to hurt somebody else!
Help, I installed the design kit under ads(windows) , copy to the circuit\MasterModels folder of the design kit, excute errata_dos.bat and prefix_dos.bat , but when I simulate circuit ADS reports error as following: Is my library version incorrect, or I have done wrong operation? Could anybody help me?
