Part Number: TPS3897 Tool/software: Hi team,
The max current is 10mA, but recommended current is only 1mA, why is there some big difference? Why the recommendation is 1mA？
Hi Sila,
Thank you for your support. I understand that TPS3897A-6P-EVM047 works as expected. Please let me know if you find any problems with the model.
Best regards,
Taka
Part Number: TPS3897 Hello team,
Is there any data for input impedance of VCC?
My customer would like to use resistor divider as supply to VCC.

My question is the following:
1. Whether output waveform will link with VCC ramp up Tr or not? If the ramp out is very fast, for example VCC going to 3.3V within 20us…
Part Number: TPS3897 Hello
When consider the delay time of TPS3897, I think the parasitism capacitance of pin of CT of TPS3897 need to be considered.
I would like to know the value, is it 1~2pf?
Thanks!

Hello,
We are using the TPS3897P with tpd(r) set to 5sec via capacitance.
When the device is powering up, we have SENSE coming up ahead of Vcc, then the ENABLE goes high about 200ms after VCC.
Since ENABLE is after SENSE and VCC…
Part Number: TPS3897 In the datasheet (April 2015), section 7.5 Electrical Characteristics, it provides a Typical Hysteresis Voltage of 5 mV but no min or max value.
At a minimum, I need to know the Maximum Hysteresis Voltage (over operating temperature…
