Electrical characteristics
LNBH29
22/31
DocID023065 Rev 3
TJ from 0 to 85 °C, VI = 12 V.
Refer to Section 5: Typical application circuits, TJ from 0 to 85 °C, DATA register bits set to
“0”, RSEL = 16 k
, DSQIN = LOW, V
IN = 12 V, IOUT = 50 mA, unless otherwise stated.
Typical values are referred to TJ = 25 °C. VOUT = VOUT pin voltage. See software description
section for I²C access to the STATUS register.
Note:
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 typical.
If VMON = 1 then VOUT < 95% of VOUT typical.
