The TIP122 is a 100V, 5A, Hfe at least 1000, darlington NPN transistor. With the base resistor of 2k2, that is about 1 or 2 mA per pin. You don't have to worry about a few mA. To answer your question: "How many transistor can be connected to arduino pins?", that will be about 100. Why do you use TIP122 ? They have a voltage drop.

I do not have it.. am I right so far? Another thing I am missing is - where can I see in the datasheet that 3.3V is enough on the base, BJTs is not Voltage , but current base, right? if I am right so far, so I need 500mA/4mA = Hfe of 125, but I couldnt find such resistor..

10/02/2012 · It could have been useful. The current available from the PIC877A outputs is probably much higher than the current available from the 4050 outputs. Check the datasheets. You can either try to remove the 4050, or replace it with a better driver. The TIP's would like at least 8mA in for 5A out, preferably 20mA.

31/01/2013 · Hey all, Since power=IV, is it possible to reduce voltage to increase current ( well of course, power being constant)? For example, a dc-dc converter has an output of about 300v at 0.4A, is it posible to reduce the 300v to get 20v at 5A? If possible, how can this be achieved practically? Any circuit/ components, please? Thanks for your responses!

Increasing Current on 78xx Series Regulators: Typically 78xx series regulators have a maximum load current capacity of 1 to 1.5 Amperes. Using this design you can double the maximum current of your 78xx regulator. This design was posted on the Net by I Hakki Cavdar of Karadeniz Technical Univ...

17/10/2013 · Does the load, R2, need to connect to the negative rail? As BobK said, if you're using an NPN, it's more usual to connect the load between the collector and …

17/11/2014 · If the Darlington is getting overloaded due to exceeding the current limit of the Darlington then an additional one in parallel would help to fix the problem ... You say that the circuit has no short circuit protection, but the 3k resistor with a hFE of 1000 means some current limit: ... The TIP122 is rated at 5A max, and without knowing the ...

/* */ Here is a calculator for transistor base resistor values. Its IMPORTANT that you read the following. Calculate the current you need to pass through the transistor when its on, that is your collector current. The current gain, beta, Hfe, is a value you can find in the datasheet for the specific trans ...

05/11/2011 · My power supply was current limited though; the circuit was pulling about 1.5A and the supply sagged to 9V (I had the current limit set at 1.5A - the supply is a CC/CV type.) I didn't make much of this because the transistor can handle 5A. Then I plugged it into a 12.6V LiPoly battery, and it worked great - for about 2 seconds.

23/07/2011 · Q5 and Q8 could be any low signal / power NPN transistors. edited: TIP120 - 127 IC Collector Current (DC) 5 A ICP Collector Current (Pulse) 8 A You better stick with TIP140 - 147, as they more powerful IC Collector Current (DC) 10 A ICP Collector Current (Pulse) 20 A Start up current for 4A motors could go up to 20A, may be more, you have to ...
