Command description: (default values are bold print)
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.
I_lim Ch1: overload behaviour of channel 1
0: Current limit 2 is activated (default)
1: Current limit 1 is activated
I_lim Ch2: overload behaviour of channel 2
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)
0 1 : Pin function is current sense output channel 1 (I_IS1)
1 0 : Pin function is current sense output channel 2 (I_IS2)
1 1 : Pin function is current sense output channel 1 + 2 (I_IS1 + I_IS2)
