Part Number: TPS3897 Tool/software: Dear experts,
Previously we were using a simple RC circuit (10K with 1uF) on the enable pin of a microcontroller. Right now, it's directly controlled by the TPS3897 like below. Of course, as the output is open-drain…
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？
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!
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.

Part Number: TPS3897 Tool/software: Hello experts,
I tried simulating the TPS3897A Transient Model with PSpice for TI, but the output was not as expected. (No errors were displayed.)
Why doesn't the SENSE_OUT change even if the SENSE exceeds 500mV…
Other Parts Discussed in Thread: TPS3899 , TPS3760 Hello, For an MCU based design,TPS3897ADRYR is used to control the Hardware reset of the MCU, My intention is if the sense input is low for 10s or more the the reset out of the TPS3897ADRYR should be…
Part Number: TPS3897 Hello Team,
Would you like to help me check the Ct range of tps3897? maybe we have one project need to set the delay time to several second, I am not sure this part has problem or not if using very large Ct.
Thanks,
Ant…
Part Number: TPS3897 Hello:
Schematic is the following:
Timming is the fillowing:
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…
