• Mode: Operation mode of the current regulator:
– no regulation
– hold only
– peak & hold with minimum peak time
– peak & hold with programmed peak time
•
I
pk
: Peak current values 1.2 A … 3.6 A
•
I
hd

•
t
p
: Peak time value 0.8 ms … 3.6 ms
•
t
fo
: Fixed off time value 100 µs … 400 µs
• H/L: Channel 4 to 6 in highside or lowside configuration
• OL+SB: open load detection and switch bypassed detection activated or deactivated
• OR/AND: Boolean Operation (parallel input and corresponding SPI Bit)
• R/L: Autorestart or Latching overtemperature behaviour
• D/F: DIAG6/Overtemp pin set as Diagnosis output of channel 6 or as Overtemperature Flag
• Ch1-Ch6: On/Off information of the output drivers (high active)
Command Description
Config. Regulator 1-3: With this command the values for the current regulation and the functional mode of the
channel is written into the internal logic registers.
Config. Ch1 to Ch6: This command writes the configuration data of the 3 configurable channels (4-6) and sets
the Boolean operation and overtemperature behavior of all channels. It also sets the DIAG6/Overtemp. pin to
Diagnosis of channel 6 or Overtemperature Flag.
Set all to default: This command sets all internal logic registers back to default settings.
Diagnosis only: When this command is sent the 12 data bits are ignored. The internal logic registers are not
changed.
Channels on/off: With this command the SPI bits for the ON/OFF information of the 6 Channels are set.
Note: Specified control words (valid commands) are executed and the diagnosis register is reset after the rising
CS edge.
Not specified control words are not executed (cause no function) and the diagnosis register is not reset after
the CS = L → H signal.
