6.9 - MISCELLANEOUS

VCC = 12V, Tamb =25°C

Note 44: Current sunk by the pin if the external voltage is higher than one the circuit tries to force.

Note 45: The threshold is equal to actual VRefO.

Note 46: In the regions of VCC where the device’s operation is disabled, the H-drive, V-drive and B+-drive signals on

HOut, VOut and BOut pins, resp., are inhibited, the I2C Bus does not accept any data and the

XRayAlarm

flag is reset. Also see Figure 16

Note 47: See Figure 10
