Part Number: TPLD801-Q1
Other Parts Discussed in Thread: TPLD801
I'm using the TPLD801-Q1 to design a power up sequency output.
As shown in the diagram, I'm using a RESET IC(TPS389001QDSERQ1)
to determine the 2V 8 level, then delay a short time before output RST.
TPLD801 I01 setting as follow:
When the SENSE input voltage reaches 1.5V, after a 1.5ms delay then output high level from RST,but the waveform is inexplicably pulled low. as follow:
yellow line: RST output to IO1 input
green line: 2.8V input to SENSE (voltage divider)
If the 0 ohm is disconnected, the RST output is correct (high level). Is there a problem with the input mode setting?
