Part Number: TL7700 Hi
My customer evaluate TL7700 for adjustable power up time.
The detect voltage is different in the start up and the instantaneous interruption.
Is there the reason for such a result?
The detect voltage is 1.25V at the start up and …
Part Number: TL7700 Other Parts Discussed in Thread: TPS3808 , TPS3890 Hello guys,
One of our customers is evaluating TL7700 for their new product. Then they faced a problem that /RESET signal repeated H/L level a few times when VCC goes down.
We have…
Part Number: TL7700 Hello
Our customer would like to add a capacitor to the SENSE pin of the TL7700. Are there any limit on the capacitance at the SENSE pin or any restrict?
In the customer, there is a possibility that a low pulse of 1 ms will input the…
Other Parts Discussed in Thread: LM137QML-SP , TPS7H1210-SEP , TL7700-SEP , UC1707-SP Hello,
Does TI have any similar parts to either the I SL7457SRHF/PROTO, EL7457CSZ, ISL706ARHF/PROTO, or the ISL72991RHF/PROTO? The cross reference tool was not very helpful…
Other Parts Discussed in Thread: TL7700 , TMS570LS20216 Hi,
Does TPS65381 only work in conjunction with TL7700 IC?
Can’t the IGN pin be driven direct from the supply to turn the device on?
Regards,

Other Parts Discussed in Thread: TL7700 Hello
The value of tpo is calculated by "tpo = Ct × 105 seconds".
But if Ct had already charged by some reasons, does tpo shorten?
Best regards,

Other Parts Discussed in Thread: TL7700 Hi All
TL7700's datasheet is written below.
(Output Pulse-Duration Setting)
When the capacitor voltage exceeds the threshold level of the output drive comparator, RESET changes from a low to a high level.
…
Other Parts Discussed in Thread: TL7700 Dear support member,
My customer use TL7700.
VCC and SENSE connect to a different power source. (VCC：5~12V、SENSE：3.3V dividing the input voltage)
In this case, SENSE voltage before VCC is supplied.
TL7700 supplied…
