Diagnostic received data (I²C read mode)
LNBH23 can provide to the MCU Master a copy of the diagnostic system register
information via I²C bus in read mode. The read mode is master activated by sending the
chip address with R/W bit set to 1. At the following master generated clocks bits, LNBH23
issues a byte on the SDA data bus line (MSB transmitted first). At the ninth clock bit the
master can:
●
●
Three bits of the register are read back as a copy of the corresponding write output voltage
register status (LLC, VSEL, EN), while, the other five bits convey diagnostic information
about the over-temperature (OTF), output voltage level (VMON), output over-load (OLF),
Minimum output current presence (IMON) and 22 kHz tone (TMON). In normal operation the
diagnostic bits are set to zero, while, if a failure is occurring, the corresponding bit is set to
one. At start-up all the bits are reset to zero.
