DocID023739 Rev 2

Refer to Section 5: "Typical application circuits", TJ from 0 to 85 °C, data register bits set to

“0”, RSEL = 16.2 kΩ, DSQIN = low, V

IN = 12 V, IOUT = 50 mA, unless otherwise stated.

Typical values are referred to TJ = 25 °C. VOUT = VOUT pin voltage.

Unit

VTH-L

Diagnostic low threshold at

VOUT = 11.8 V

VSEL0 = 1, VSEL1 = VSEL2 =0

VTH-L

Diagnostic low threshold at

VOUT = 15 V

VSEL1=0, VSEL0 = VSEL2 = 1

If the output voltage is lower than the min. value the VMON I²C bit is set to 1.

If VMON=0 then VOUT > 80% of VOUT (typ.)

If VMON=1 then VOUT < 95% of VOUT (typ.)
