Part Number: TL7705A Hello,
Is it OK to use the TL7705 (5V) supervisor in a 12V application with a custom threshold by adding a resistor divider in series with the sense pin? Please review the TL7705A circuit below.
Thank you.

Part Number: TL7705A Other Parts Discussed in Thread: TL7705B , , TPS3703-Q1 , TPS3840 Hello,
Please tell me which of the TL7705B and TL7705A has a narrow range of VIT- from -40℃ to 125℃?
In data sheet of TL7705B, VIT- is 4.45V to 4.65V in "TA = full range…
Part Number: TL7705A We are testing a power supervision circuit that monitors 2 voltages: 12V and 5V.
This circuit activates an enable signal (EN_SQCR) for the power sequencer that follows. This signal is active at a high level. It turns out that if…

Why cannot they…
Part Number: TL7705A Hi, This is Masaharu Takahashi from TI Japan.
could you tell me how much tolerance do you expect for those resistors ?
how much can you accept as tolerance for those resistor ?
Part Number: TL7705A Other Parts Discussed in Thread: TL7705B Hello.
Can I set a delay of 1s by using a large capacitor such as 70~80μF for CT?
1.3 * 10000 * 77μF = 1s
Similarly, in the case of TL7705B, Can I set a delay of 1s by using a large capacitor…
Hello Satoshi-san,
Regardless of the reference voltage variation, the resistor R1 is trimmed to ensure the output voltage range specified in the datasheet for the TL7705A device.
Best,

Ciao Alessandro,
this is usually done by the help of an additional switching stage using a BJT, JFET or MOSFET which needs a minimum voltage to turn-on or turn-off. See figure 14 and 15 of datasheet of TL7705A, e.g.:
