Hi, No, but this is the next error: VIH needs to be way more than 5V. Recommended more than 9.5V....VCC. Klaus Hi! That seems to forfeit the purpose of the driver? My signal is coming from a microcontroller, therefore the maximum I can raise the signal to is 5V. Also, I realized that U8 and U9 have different outp
It is a tiny little mosfet so of course its max current and max power dissipation are also low.
The 7812 regulator has a max Vin of 35V. If you get spikes just below this voltage you could drive it into malfunction, especially without any kind of capacitors to stabilize it.
Thanks, but supposing we are PWM dimming a 48V string of LEDs....then the current to the LEDs is going on and off, and the voltage across them has a ripple in it in phase with the PWM dimming, so in this case of PWM dimming, does the AC limit apply?, since there is an AC content to the LED current waveform.? So what I am saying is, 60VDC is the
Hi, I am trying to use a TP4056 based CC-CV Li battery charger (along with battery) to make a lamp that automatically switches between AC and Battery. I choose the TP4056 CC/CV charger because its small, gives upto 850mA of current and seems to be fairly reliable one. The LEDs that I will use will be 0.5W ones which don't need heatsink. I plan t
The graphs on a datasheet are only for a "typical" device. Some devices are minimum and others are maximum. Adding negative feedback reduces the differences between them.
I might be able to help you solve your X class mosfet issues, but you would need to contact me with much more information than can be supplied here. Does it have to be TO-3? Is something like this suitable? VDSS, max, (V) 1200 ID(cont), TC=25C, (A) 26 RDS(on), max, TJ=25C, (Ω) 0.5 Ciss, Typ, (pF) (...)
The battery type is 3.7V/890mAh Li-on battery. The main supply is max 36V and the operating voltage is 4.2V. Now I'm totally confused. First of all, that is not the schematic symbol for a P-channel mosfet; that's the schematic symbol for a box with 6 terminals. Are you saying your 36V supply is connected to the bot
Hi, I need to drive 5mAmps in a load up to 20Kohm from 9V resistor. In order to do so I made a boost converter to boost the 9V up to 120V. 97999 The pulse driving the mosfet 140 micro second and the duty is 14 micro second this was the max current in the coil = 9*14/120 = 1.05 Amp and the average current consumed by
Dear All, can anyone give me idea for full bridge topology.. i am designing bridge rectifier from mosfet (freq=hz) i designed half wave rectifier with single mosfet and it works gud.. the main idea behind designing this is to do the less losses (voltage drop while max current flowing) please help me out..
Hi all, I am planning to make an H-bridge for a DC motor. Here are the specs Supply voltage range - 12V to 30V max current ≈5A I am planning to use IRF530 and IRF530 and IRF9530 mosfets The gate driver I have planned to use is this. Is this and the two mosfets are good choices?
If you are making a h bridge circuit, I think you should go for a Hi side and Lo side driver circuit. You can use IR2110, IR2010 for the purpose and they are easily available. Just go for its datasheet on the net. But the max current is 3A. Btw you can use comparators
1. only an ohm of resistance will make PIC taking larger bias current which can damage PIC ADC i/ps, as pointed by hemnath. Use resistance of 100k. Check google for reference circuits. 2. How r u providing +12V from PIC to mosfet? The MCU can provide 5.5V max. R u using any driver? Plz specify. Also, the i/p is 12V but drain supply is just (...)
Your problem is not so simple. The SOIC-8 package current limit is only linked with the lead to soldered PCB connection. The mosfet max current rating is defined by its manufacturer. Its definition may be (or may not be) dependent upon e.g. pulse frequency and duty cycle. The prudent advice is to choose the minimum rated (...)
Your circuit will not work with AC. The circuit will work as long as you provide enough base current and the collector current is not higher than the specified max current for the transistor. The power consumption of the transistor and temperature should be within limits too. A mosfet doesn't need the (...)
More info is needed.... output pulse DC Voltage of 15V-72V max. pulse current 1.5amps Pulse frequency 1Hz - 7kHz controlled with ??? ( potentiometer , ext. voltage..... ) What is a split second in number values ? ( Pulse OFF-time = voltage 0V ) Is this pulse OFF-time constant value ? What is the load ? ( Inductive, capacitive or pure resis
IRLZ44N has max current of cca. 40A and RDSon of cca. 22mOhm, vs IRLZ34 which has max current of cca. 30A and RDSon of cca. 50mOhm. So, either of those mosfetS should work for you without any difference. I use IRLZ44N to dim 60+W of LED without any problem.
The max current that the mcu pin can give can be found in the datasheet of your mcu in the electrical characteristics section, it is not a matter of the power supply. I assume that there are no drivers on board , if there are then you may be able to connect the motor to them Do you just want to be able to start stop the motor or you intend to c
The max Vgs is specified in the datasheet (usually around 20v) , as long as Vgs is lower than this voltage there is no problem. The mosfet gate doesn't draw current like the base of the transistor, there is just a gate capacitance that needs to be charged in order for the mosfet to conduct. Alex
He is talking about the output transistor of the optocoupler, that is where you are getting the drop not the mosfet You can either use a lower resistor in the input diode of the optocoupler (assuming that you don't go above the max current) ot use a higher value resistor in the transistor output, you will get values closer to 0 but still (...)
