Bit
DB1 Diagnostic Byte:
Thermal warning active (D7 = 1)
Diag not actived or not terminated (D6 = 0)
Diag terminated (D6 = 1)
Channel 1 current detection
Output peak current < 250 mA (IB2 − D7 = 0) − open load (D5 = 1)
Output peak current < 100 mA (IB2 − D7 = 1) − open load (D5 = 1)
Output peak current > 500 mA (IB2 − D7 = 0) − normal load (D5 = 0)
Output peak current > 300 mA (IB2 − D7 = 1) − normal load (D5 = 0)
