    To drive 6 LEDS in parallel

    Yes Thanks for the reply I am using Amber LED LNJ447W84RA1 and Mosfet BSN20-7. Attached datasheets for your reference. I want to use 6 LEDs in parallel configuration with Mosfet control by Micro and If I connect one current limiting resistor of 200 ohms; will the circuit is fine? Please guide me

    To drive 6 LEDS in parallel

    Hi, In my project I need to drive 6 LED's in parallel with the 3.3V voltage supply. Can I drive all 6 LEDs in parallel with a single MOSFET? Each LED requires only 5mA and The gate of MOSFET will be driven by Micro-controller. How far this approach is correct? Please let me know ASAP. Thanks...

    LM334 adjustable current source Problem

    Hi, I am using LM334 in my project. I have configured LM334 in such a way that the output current is 2mA constant by placing Rset resistor value as 34 ohms as per LM334 datasheet and I have connected load of 10K across the V- pin and ground. Here I am facing a problem, if I change vary the load...

    Which is better Analog Switch or Relay

    Hi Frank, Thanks for your response. The Switch will be ON for 3 minutes (maximum) continuously and later it is switched off.

    Which is better Analog Switch or Relay

    Hi, In my project there is a requirement of switch that will enable constant current of 1mA to flow when switch is ON and voltage level is 28V. Which one is more reliable for this requirement analog switch or Relay? It would be great if anyone could answer this clarification Thanks in advance!

    Constant current output

    The circuit must source 2mA and the design has to be accurate so that the output source current has to be with in 5% tolerance i.e 1.9mA to 2.1mA

    Constant current output

    Hi, I need to design a circuit which provides constant current output of 2mA for the Variable resistance load(which varies from 350Ω to 45KΩ) in my Project. When the load varies, the output current should be constant and Voltage can be varied in order to maintain current as constant. Please let...
