Preliminary specification
TDA9151B
I2C-bus commands
Slave address: 8C HEX = 1000110X BIN
READ MODE
The format of the status byte is: PON PROT 0 0 0 0 0 0
Where:
PON is the status bit for power-on reset (POR) and after
power failure:
• Logic 1:
– after the first POR and after power failure; also set to
1 after a severe voltage dip that may have disturbed
the various settings
– POR 1 to 0 transition, VCC = 6.25 V (typ.)
– POR 0 to 1 transition, VCC = 5.75 V (typ.)
• Logic 0:
– after a successful read of the status byte.
PROT is the over voltage detection for the scaled EHT
input:
• Logic 1:
– if the scaled EHT rises above the reference value of
3.9 V
• Logic 0:
– after a successful read of the status byte and EHT
<3.9 V.
Remark: a read action is considered successful when an
End Of Data signal has been detected (i.e. no master
acknowledge).
