TP
Temperature prewarning: high = warning
(overtemperature shutdown see remark below)
Normal operation: high = output is on, low = output is off
1
Status LS1
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off)
Normal operation: high = output is on, low = output is off
2
Status HS1
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off)

SCD
Short circuit detected: set high, when at least one output is switched off
by a short circuit condition
14
INH
Inhibit: this bit is controlled by software (bit SI in input register) and
hardware inhibit (pin INH). High = standby, low = normal operation
15
PSF
Power supply fail: undervoltage at pin VS detected
Note: Bit 0 to 15 = high: overtemperature shutdown
