Part Number: TL7705B
Other Parts Discussed in Thread: TL7702B, TL7733B

Customer inquires SENSE-pin internal resistance values for sensing over 4.55V using a resistor divider.

The note 1 description for R1 and R2 vales etc. is deleted from the revised TL7705B data sheet of SLVS037N on page 1 and page 9.

Can you inform us R1 and R2 values?

    Hello,

    Please note the following:
    TL7702B: R1 = 0 Ohm, R2 = Open, Vx = Vref1
    TL7705B: R1 = 23kOhm, Rs = 10kOhm, Vx = 1.43V
    TL7733B: R1 = 11.3kOhm, Rs = 10kOhm, Vx = 1.43V

    Note that these are typical and not guaranteed values. There will device to device variation.

    Best,
    Michael
