Table 3-2. Output Data Protocol

Bit

Output (Status)

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

8 n. u. Not used

9 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
