TPS1HC30-Q1: Questions for datasheet - detailed design procedure and KCL

Josh Wei

Part Number: TPS1HC30-Q1

Tool/software:

Hi Team,

Here are four questions need your support. Thank you!

1. When calculating WCA today, is there a problem with the resistance range below? The resistance on the left is larger, and the resistance on the right is smaller.

2. In the example in the figure below, the Ksns values at 6A and 20mA are 1814 and 11814 respectively, which should be a problem;

3. For the GND network, when connected to a capacitive load, can the 1kΩ resistor be replaced with a 0Ω resistor?

4. Are the maximum and minimum values of KCL in the figure below also 6sigma distribution?

Best Regards

Hi Josh,

1. Thanks for pointing that out - regardless, as you pointed out, the RSNS value should be in between those upper and lower limits.

2. I believe this is a typo as well, it should be 1814.

3. If using a capacitive load, this GND network resistor can be DNP, just a diode can be used. A 0Ohm will short the diode.

4. The data points in this graph are taken from the KCL specification in the Electrical Characteristics.

Thanks,

Patrick

Hi Patrick,

Thanks for your reply. When will these typo be correct in datasheet?

Besides, what is KCL specification and does this meet 6 sigma?

Best Regards

Josh
