TLE6288R
SPI
The following parameters and functional behavior can be programmed by SPI:
• Current regulation mode (mode): for each of the 3 highside channels individually the operation mode can be
set.
– “no current regulation”
– current regulation “hold only”
– current regulation “peak & hold with minimum peak time”
– current regulation “peak & hold with programmed peak time”
• Peak Current (I_pk): for each of the 3 highside channels individually the peak current value for P&H current
regulation can be programmed. The current range is 1.2 A to 3.6 A.
• Fixed off time of the current regulator (t_fo): for each of the 3 highside channels (Ch1 to Ch3) individually the
fixed off time for all modes with current regulation can be programmed from 100 μs to 400 μs.
• Hold current (I_hd): for each of the 3 highside channels (Ch1 to Ch3) individually the hold current value for P&H
and hold only current regulation can be programmed. The current range is 0.7 A to 2.0 A.
• Peak time (t_p): for each of the 3 highside channels (Ch1 to Ch3) individually the peak time value for P&H
current regulation can be programmed. The time range is 0.8 ms to 3.6 ms.
• Highside/Lowside configuration (H/L): Each of the 3 configurable channels (Ch4 to Ch6) can be
programmed for use as Highside switch or Lowside switch.
• Open load and switch bypassed detection activated or deactivated (OL+SB): For each of the 3
configurable channels (Ch4 to Ch6) the open load and switch bypassed diagnosis can be deactivated. In
lowside configuration the open load and the short to GND detection can be deactivated, in highside
configuration the open load and short to battery detection.
• Boolean operation (OR/AND): For all channels generally the Boolean operation of the parallel input signal
and the SPI bit of the corresponding channel can be defined.
• Overtemperature behavior (R/L): The overtemperature behavior of the channels can be programmed by SPI.
Autorestart or latching overtemperature shutdown can be selected (for all channels the same behavior).
• DIAG6 or overtemperature flag (D/F): With this SPI bit the function of the DIAG6 / Overtemp pin is defined.
This output can work as diagnosis output of channel 6 or as Overtemperature Flag.
