Output Data Protocol

Output (Status)

Bit

Function

Temperature prewarning: high = warning

(overtemperature shutdown see remark below)

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)

Status LS1

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)

Short circuit detected: set high, when at least one output is switched off

by a short circuit condition

SCD

Inhibit: this bit is controlled by software (bit SI in input register) and

hardware inhibit (pin INH). High = standby, low = normal operation

INH

PSF

Power supply fail: undervoltage at pin VS detected

Note:

Bit 0 to 15 = high: overtemperature shutdown
