Part Number: TMCS1126-Q1 Other Parts Discussed in Thread: UCC21750 Tool/software: Hi~
What is the maximum power consumption of TMCS1126-Q1 and UCC21750QDWRQ1 ?
I can not find it in the datasheet.
Part Number: TMCS1126 Tool/software: Hi there,
This is Racheal from AA3 team in Shenzhen. My customer is now using TMCS1126 in PFC current detection. When the power ramping up, the output signal of TMCS1126 is toggling with amplitude of 60mV, shown as…
Part Number: TMCS1126-Q1 Tool/software: Hi,
We are using TMCS1126C5BQDVGR hall effect sensor in our battery charging control module .We are not using Voc & oc pin. In datasheet it is recommended oc pin to GND & Voc pin to Vs if not used. But our…
Part Number: TMCS1126 Tool/software: Hi team,
With OC pull up to VS, when test OC pin during power down, there is many glitch on OC pin. In below waveform, blue is VS. purple is OC pin. you can see significant glitches during power down. After zoom in…
Part Number: TMCS1126 Tool/software: If I have a close-loop controller with a dc motor using Ripple Current for position/counts and would like to measure the counts external from this system do you have a recommendation?
Part Number: TMCS1126 Other Parts Discussed in Thread: DRV5055 , DRV425 Tool/software: Currently designing a PCB for measuring current of motor, no wires will come to PCB, only through Magnetic flux need to measure current, can you suggest any sensor for…
Gary,
Here is a correction on expected noise. I placed the 1.57 outside the Sqrt. I highlighted the updated values.
Assume 1/f noise =not an impact
A1 = 25mV/A
Noise density: 150µA/√Hz
Bandwidth: 550kHz
Assume single pole at output: 1.57

Part Number: TMCS1126 Other Parts Discussed in Thread: TMCS1123 Tool/software: Hi team,
Is there a data regarding maximum continues input current when 70C degree or 80C degree ambient temperature? I would like to know max current for TMCS1126 and TMCS1123…
Part Number: TMCS1126 Tool/software: In the instructions (SBAU452) it says:
But in the data sheet:
In the DS, GND is pin 9 and Vs pin 4, not 8 and 3 as shown in the user guide.
I am going to assume that the data sheet is correct!
