Part Number: TPS3890 Other Parts Discussed in Thread: TPS3842
Tool/software:
Hello Team,
Customer is looking for supervisor as below conditions:
1. Adj threshold
2. Open Drain
3. Active LOW
4. RESET with no delay (uS level should be ok…
Part Number: TPS3890 Tool/software: Hi Team,
According to the Device Comparison Table, for the TPS389018, VITN = 1.73V, VITP = 1.740V.
Applying this to formula (1), VHYST = [ (1.74 - 1.73) / 1.73 ] * 100% = 0.578%, which is close to the 0.575% listed…
Part Number: TPS3890 Other Parts Discussed in Thread: TPS3703 , TPS3899 Tool/software: Hi, team.
I consider using TPS3890. However, I'm having trouble with a big error of reset time delay.
You have other ICs to set more accurate delay? Or is there…
Part Number: TPS3890 Tool/software: Hi team,
I would like to check that how to calculate tPD(f) of TPS389001DSER?
In datasheet only show the normal value of tPD(f) under CT=open, and VDD=3.3V or 5.5V. How about the situation when CT is not open and…
Part Number: TPS3890 Other Parts Discussed in Thread: TPS3840-Q1 , TPS3842-Q1 Tool/software: Hi Team,
According to the data sheet, tPD(r) is calculated as follows: tPD(r)[SEC] = CCT x VCT ÷ ICT + tPD(r)(nom) *tPD(r) = SENSE (rising) to RESET propagation…
Part Number: TPS3890-Q1 Tool/software: Hello, Based on datasheet “5 Device Comparison Table”, my customer calculated VHYST [%]. (Please refer to the attached Excel file.) For most devices, calculated VHYST [%] is almost equal to VHYST(typ)= 0.575%. However…
Part Number: TPS3890-Q1 Other Parts Discussed in Thread: TPS3899 Hi,
I am looking for a supervisor or pushbutton controller that has a programmable output delay and monitoring input setup time.
Specifically, I am looking for a device that can monitor…
Part Number: TPS3890 Hi expert,
Customer used TPS389033 and used 0.01uF C(CT) which hope to have 10ms delay time.
However, we didn't see the 10ms delay time happened. Could you please help advise what might goes wrong?
p.s. the time division is…
Part Number: TPS3890-Q1 Hi team,
My customer want to know tPD(r) min/MAX value. In the datasheet there are only nominal value.
They want to calculate by using min/MAX value. Not NOM.
Regards,
Youhei MIYAOKA
Part Number: TPS3890 Looking at the datasheet I expected this to work as the threshold is 0.25*VDD = 1.25V. But in my board reset is always low. Could be another problem but I just wanted to check this out too.
5V is up, 3.3V is up, 1.8V is up and PGOOD_1V8…
