1. Diagnosis Only : Reads out the diagnosis register. This command has no other influence on the

device.

2. Output Configure : Configures the behaviour of the Power Outputs.

0: Current limit 2 is activated (default)

1: Current limit 1 is activated

0: Current limit 2 is activated(default)

1: Current limit 1 is activated

Restart / Latch: overtemperature behaviour of the IC

0: Automatic autorestart of a channel after cooling down(default)

1: Latching "off" of a channel at overtemperature

Slew rate: Switching slew rate of channel 1 and 2

0: fast switching (slew rate 1) (default)

1: slow switching (slew rate 2)

3. I/O Configure : Configures the behaviour of the I/O Ports.

Status / SPI : Output of diagnostic information of the IC

0: Diagnosis output serial with one status output per channel (ST1, ST2)

1: Diagnosis output with SPI (SO) and Fault Pin / Sense Pin

Parallel / Serial Input : Control of the output channels

bit3 bit2

0

0 : Control of channel 1 and 2 with parallel input (IN1, IN2) (default)

0

1 : Control of channel 1 and 2 with combination (OR) of serial and

parallel input signal

1

0 : Control of channel 1 and 2 with combination (AND) of serial and

parallel input signal

1

1 : Control of channel 1 and 2 only with SPI

Sense / Fault : Function of the Sense / Fault / ST1 output

bit1 bit0

0

0 : Pin function is "general Fault pin"(default)
