TDA8595
I2C-bus controlled 4 × 45 W power amplifier
Table 11. Data byte DB1
Bit
Description
D7
temperature pre-warning
0 = no warning
1 = junction temperature too high
D6
speaker fault channel 2 (missing current)
0 = no missing current
1 = missing current
D5 and D4 channel 2 DC load or AC load detection
if bit IB1[D2] = 1, AC load detection is enabled, bit D5 is don’t care, bit D4 has the
following meaning
0 = no AC load
1 = AC load detected
if bit IB1[D2] = 0, AC load detection is disabled, bits D5 and D4 are available for
DC load detection
00 = normal load
01 = not valid
10 = line driver load
11 = open load
D3
channel 2 shorted load
0 = not shorted load
1 = shorted load
D2
channel 2 output offset
0 = no output offset
1 = output offset
D1
channel 2 short to VP
0 = no short to VP
1 = short to VP
D0
channel 2 short to ground
0 = no short to ground
1 = short to ground
Table 12.
Bit
D7
D6
Data byte DB2
Description
power-on reset and amplifier status
0 = amplifier on
1 = power-on reset has occurred; amplifier off
speaker fault channel 4 (missing current)
0 = no missing current
1 = missing current
