But if increased current capacity is your only goal, there is a big trap you need to look out for. My circuit is 15 volts.

The battery charge may not have intelligent soft start and irfp450q the charger hooking up to a dead battery. I am assuming these are too light for the duty.

Take a look at this one. It seems this “entry level” charger” has very little margin before exceeding the component limits.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at If the impedance gain or resistance gain is too high, you need more stages of MOSFET buffering to prevent overloading the gate resistors due to Qgs charge switch datashet and switch frequency.

Misterbenn Active Member Mar 1, If so, can you suggest some part numbers?

Maybe a little overkill but, other than the copper plates that carry the current, there is no heatsink. As Tony points out, there will usually be some other parameter that changes along the way. Pins 11 and 14 are the 2 outputs of the chip.

You must log in or register to reply here. A project I am doing right now needs to switch 60Amps DC. You need to know what affect other parameters may have on your circuit. So, it will only carry 14 amps if you can keep the case at 25C while it is pushing out 78 watts of heat. Lets take that number down to the graph at Figure 4. One of the pair of There is also a visible crack in the case of the same Mosfet. Articles Top Articles Search resources. Give them a good look, especially those close to the hot heat sink.


Media New media New comments Search media. So when carrying 14 amps, it will be dissipating about 78 watts of heat. Datasheets, Manuals or Parts.

So it will only handle 14 amps continuous if the case is kept at 25C all of the time. Pin 11 which the burned resistor connects to has a very low resistance to ground compared to pin One important fact that everyone need to be aware of when choosing mosfets, is that the current rating has a fine print disclaimer that causes problems if not taken into account. If the case is at 25C, the junction is at 94C.

Potentiometer Questions Started by norbss Yesterday at The unit belongs to a neighbour and he said it just quit working; he doesn’t know if it was running hot before it quit. Not as easy as it sounds.
