Part Number: LM555 Other Parts Discussed in Thread: TLC555 Dear Team,
Out customer need RC timer solution: similar with 555 oscillator.
operating temp : -40~+105
Please advise. Thanks.
I appreciate all your efforts! Unfortunately non of the provided solutions worked for me. However, after a lot of experimenting, using an open collector-collector circuit connected to the trigger pin on LM555 and PIC microcontroller did the job…
Part Number: LM555 Dear Sir.
I tested the circuit below.
The load is a filament heater with 3.3Ohm,
but the LM555 timer was sometimes dead and LED was burnt.
Could you check what is problem with this circit ?
Part Number: LM555 Hi Team, May I ask for your help? Kindly see customer concern below: " At this moment everything is highly conceptual, what we are needing is a timer that can perform the speeds of a photographic shutter. We are very interested in…
Part Number: LM555 Hi Team,
Our customer is designing a push-pull converter and they intend to use the LM555, but it will with no feedback and no dead time. Would this be suitable for this use case? Are there any potential risks of having open-loop and…
Part Number: LM555 Other Parts Discussed in Thread: CSD19534KCS Dear Sir.
I am developing the power module with timer function.
After 12V DC Jack inserted, and 5 minutes later, we want to switch off the 12V power connected to heater.
12V DC JACK --- LM555…
Part Number: LM555 Dear Sir/Ms.
My client uses LM555 to generate 40% Duty but his actual result is 60% Duty. The customer said that he adjusted the resistance ratio of RP1 to RP2, the maximum duty is only 50%. The customer's schematic is like an attachment…
