Last edited irdz30 a moderator: I can tell by the sound of the pump, and allot less flow is being produced. You must log in or register to reply here. And yes, we need to know the spec of the pump motor I’m not an electro-tech guy but a mechanical engineer, way over my head.

I think even 10K’s would work, someone out there would know. Started by fastline Yesterday at 8: With a 5V supply the datasheet of an ordinary shows that its output goes as high as only 3. Replacing a 4 pin leaded inductor with jrfz30 2 pin Started by gkmaia Yesterday at Articles Top Datashee Search resources.

Maybe the little 9V battery “falls on its face” when the high starting current of the motor causes its voltage to drop which causes a false trigger of the ?

I tried doing the same thing with mine to see dqtasheet it was helpful in regards to the effect of the manual switch but it was not. Somewhere it says the motor is a 6V motor so maybe 9V is too much for it.

Nowhere says the size of the 9V battery. There are datasjeet few differences compared to the one I have tried and shown above. At the time I didn’t have the manual switch installed. The diagram was only to suggest a way to manually turn the pump on – yes a complete redesign is necessary.

To be honest, the LM isn’t really needed, it could be iirfz30 directly off the battery. Potentiometer Questions Started by norbss Idfz30 at Is a little 9V battery able to produce enough power to drive the motor? Now when I use the manual switch it sets off the timer. It might be necessary to use two diodes to form a simple OR function, but you might get away with changing the gate resistor to say 1K and having another 1K via your now low-current switch. On the LM dataxheet have a capacitor which is wrong in parallel with the ohm resistor from the output to the ADJ pin but the datasheet has only the resistor or the resistor with an added parallel diode when the ADJ pin has a capacitor to ground.


Your schematic does not show a part number for your Mosfet.

Wooops, I think I need to move the manual switch diode out ahead of the pin 3 diode. Consider some small 0. OP is commonly used around here in the forum. By that I do not mean that Jacbk will be one of them.

Both the schematics in the 1st post of this thread show a 9v battery, but I will wait until jacbk replies – at least we are not wasting our time. To participate you need to register. Jacques, Instead of a relatively high current switch irfa30 operate the pump motor, why not just provide a low-current with series resistor input to the MOSFET?

Way too low for most Mosfet gates. Perhaps a bipolar transistor would be better?

I’ve read so many threads where the original OP is OP right? Keep it simple and cheaper! Thread starter jacbk Start date Mar 6, Is this what you mean?
