32 / 38 page ![]() Electrical characteristics LNBH26 32/38 Doc ID 022771 Rev 1 Refer to Section 5, TJ from 0 to 85 °C, All DATA 1..4 register bits set to “0” except VSEL1 = 1, TEN=1, RSEL = 11 k Ω, DSQIN = HIGH, VIN = 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 system register. Note: If the 22 kHz tone parameters are lower or higher than the above limits, the TMON I²C bit is set to “1”. Table 19. 22 kHz tone diagnostic (TMON-A/B bit, STATUS 2 register) characteristics Symbol Parameter Test condition Min. Typ. Max.
