Hello sir, I didn't get any related information about 588vn1 ic from above links. Thank you.

Hello sir, sorry for late reply, please find the below attachment for the datasheet of 588vn1 IC. original datasheet was in Russian , so I translated to English. Thank you.

hello sir, what you got is correct , it has 28 pins. but it's not same as intel 8259 ic. because pins configuration are different in 2 ic. for ex. there is status register pin and vector address pins are there in 588vn1 where in 8259 its not there , how can i relate it?. thank you.

Hello. I, need a help to find the proper datasheet of a Russian interrupt controller. I found the the datasheet of this IC where there is no working application and only pin information is there. So, can anyone suggest any document related to this IC. Part number : 588VN1 Thank you.

I tried to search for ic which will do the whole job. But I didn't got any.

Pump was filled with water. And I didn't measured the flow rate. But I can see the flow rate change difference while changing the pwm.

Sir. While I am testing pump in stand alone mode it took around 1.3 A at Max speed. (12 v input) Input to dc dc converter is 18-36 V. My problem is if there is a overcurrent of fault happens to load, it will cause the loading problem. To avoid this I have to design a circuit or isolation. Or...

Pump is actually a coolant pump of Ford car engine. I am supplying 12 volts from a dc dc converter.

Load is small pump which has excitation of 12 v and can be controlled speed by pwm. Sir. Since I am new to thease concepts. Please suggest any documents or circuits .

Thank you for your reply. Sir. For preventing overcurrent or short circuit in the load i am isolating dc converter with lm338 voltage regulator in which I can set current limit using resistor. Since load current is 1.5 A . I have to use high wastage resistor. Problem is size of high wattage...

hello, i am working on a load, by giving continous 12v power supply and current consumed by the load is max of 1.5 A. there is a resistor between load and supply. power consumption (heat dissipation) is more at the resistor. i am finding difficulty while designing in pcb board. bcuz size of the...

i want to sample the dc power, i dont have much knowledge about arm, or stm32, can you suggest any ic which can be used for sampling.

output voltage is dc and sampled data will be fed to fpga. so what micro controller wil do the sampling.

ok sir , but i need the proper micro controller which can do the sampling, please suggest any.

Hello, Please help me to create the sampling processing circuit. i have to create the voltage and current sampling processing circuit, Then the output of circuit will be fed to processor to further operation. output voltage of my original circuit will be maximum 250v and current is 30A(peak...
