Bit
Output (Status)
Register Function
0 TP Temperature prewarning: high = warning
1 Status LS1
Normal operation: high = output is on, low = output is off
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off); not affected by SRR
2 Status HS1
Normal operation: high = output is on, low = output is off
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off); not affected by SRR
3 Status LS2 Description see LS1
4 Status HS2 Description see HS1
5 Status LS3 Description see LS1
6 Status HS3 Description see HS1
7 n. u. Not used
8 n. u. Not used
9 n. u. Not used
10 n. u. Not used
11 n. u. Not used
12 n. u. Not used
13 OVL
Over-load detected: set high, when at least one output is switched off
by a short-circuit condition or an overtemperature event. Bits 1 to 6 can
be used to detect the affected switch
14 INH
Inhibit: this bit is controlled by software (bit SI in input register)
High = standby, low = normal operation
15 PSF Power-supply fail: undervoltage at pin VS detected
