Part Number: LMC555 Tool/software: The following is the timing accuracy listed in the datasheet, For example, it is 1.1ms (Typ) at Vs=5V, Is this 1.1ms (maximum variation 1.2ms) regardless of the operating frequency? Or did you mean that it varies by a…
Hi Owain,
The section you highlighted is correct. The reset pin is not related to power on reset. Power on reset circuits are used in designs to provide a known state on power up. The timers do not have power on reset circuits. The reset pin has never…
Part Number: LMC555 Hi,
The following changes have been made to the Revision N datasheet: However, the yellow highlight is VS=1.5 V. Is this VS=5 V correct?
If so, do you plan to modify the datasheet? Could you tell me when you will modify it?
Best Regards…
Part Number: LMC555 Hello, I'm utilizing the LMC555 timer to produce PWM with a duty cycle between 45-55% and a frequency of 84.5KHz. The timer is set up in A-stable mode, and I'm facing challenges in understanding two key aspects. Firstly, I have…
Part Number: LMC555 Dear,
My name is Yonemura from Omron corporation.
Please tell me about PCN#20240306005.1.
1. Is there an English datasheet for Rev.M? Or you can use Rev.N Japanese data sheet.
2. Is there any material comparing RevM and N?
Best regards…
Part Number: LMC555 Other Parts Discussed in Thread: TLC555 Dears,
At present, the circuit we design first outputs a high level signal (2.6V or 3.3V, with a maximum drive current of 20mA) to the second pin of the LMC555CMX chip, and then power on the…
Part Number: LMC555 Good day Colleagues,
I understand, the threshold highly dependand on external RC tolerances, but could you tell me how this circuit inside depends on temperature?
the datasheet says the paramiters at +25 degC. Could you tell me what…
Part Number: LMC555 Other Parts Discussed in Thread: NE555 , TLC555 Hi,
In LMC555CMMX/NOPB datasheet for achieving 50% duty cycle discharge pin is kept as high and control pin is left open. Any specific reason for doing the same?
And in the same circuit…
Part Number: LMC555LMC555の50%デューティ回路構成で発振周波数を2kHz設計しましたが、評価では周波数は1.792kHz、デューティは57%でした。デューティが50%に達しないのは、OUTPUT端子のHigh電圧がV+電圧まで上がっていないからだと思いますが、なぜOUTPUT端子の電圧が11V程度までしか上がらないのでしょうか?V+端子に印加される電圧は12Vで、OUTPUT端子には回路図以外の負荷は接続されていません。回路図と波形を添付しておりますので、ご対応ください…
