Legend of SPI Command Table:
Mode: Operation mode of the current regulator:
a) no regulation
b) hold only
c) peak&hold with minimum peak time
d) peak&hold with programmed peak time
I_pk : Peak current values 1.2A - 3.6A
I_hd : Hold current values
0.7A - 2A
t_p : Peak time value
0.8ms – 3.6ms
t_fo : Fixed off time value
100µs – 400µs
H/L : Channel 1-3 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 for the current regulation and the functional
mode of the channel is written into the internal logic registers.
Config. Ch1- Ch6 : This command writes the configuration data of the three configurable channels (4-
6) and sets the Boolean operation and overtemperature behavior of all channels. It also and 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 = LÆH signal.
