A whole MCU port of 8 pins can sometimes supply only 10mA as a whole, despite that an idividual pin is also capable of supplying 10mA, but if 1pin takes all the current, the rest will have nothing.Whirlpool ES50R123-45D electric water heater parts | Sears PartsDirect. If the power comes from the source instead of the MCU, this will allow you to power more things and just ground them through the MCU's pin. This is only valid when you are powering something from the MCU's pin. A MOS has very low Rds, which should be better for your purposes. Its normally a good idea, but it will eat a part of your voltage, which will be applied on the transistor itself(collector-emitter junction) and the power over the wire will drop even more. It can be used to fine control the current.

If you set it to 22mA, but the resistance is 205 Ohms, you will get about 17mA, because the source is not 4.51V. On the other hand a BJT can be used, but it will be controlling the current through the wire, depending on the base current, the resistance of the wire and the voltage source connected to the collector and emitter. The reasons are that the MOS will allow most of the voltage(from the 3.6V battery) to be applied over the wire and the current will depend only on the resistance. Of course when you decrease the length of the wire, and the power for it, you will have even less heat.Ī MOS FET would be a better choice. Here the wire must be very short, because with 22mA, it will not heat a lot, and the bigger it gets, the less will it heat.ĭriving from a 3.6V battery, means you have to decrease the resistance, or the current will not be the same. This of course depends on the length of the wire and changing the length will change the resistance. If you want to have 22mA and 4.51V, this means that the wire's resistance is 205 Ohms. The wire is just a component like any other, it has a resistance and depending on the voltage through it, the current will change. So, on using an NPN BJT, wouldn't it work properly?

Also, I read on a website that while using MCU, it's better to use a high side switch, since MCU always needs to be ground.

I researched about load switches which use P-channel MOSFET, because of it's lots of advantages, I am confused if it will be a better choice or not, if someone can suggest.The problem that I am confused about is, will my circuit work properly with 3.6V at source? Does 4.51V generated across heating element have any significance in regards to this?

Since, I'll have to provide a source voltage for the driving circuit, I plan on using a 3.6 V battery.

I am using MCU connected to this nichrome wire through current driving circuit.

#Circuit xdiagram with heating elements driver

I am planning on using a NPN BJT as a current driver to limit the current at a constant rate and because my current requirement is lower than 1A, I think NPN BJT will be a better option than using MOSFET. I have already done computation and I need current of approximately 22mA to generate that power, also the voltage that will be generated across the heating element will be 4.51V. For my project, I need to heat up a nichrome wire (which acts as a heating element) and provide a power of 100mW to it.
