TLE6288R Datasheet, PDF (16/23 Pages) Infineon Technologies AG – Smart 6 Channel Peak&Hold Switch

Preliminary Datasheet TLE6288 R
The 16 bit SPI is used to program different IC functions
and values, turn on and off the channels and to get de-
tailled diagnosis information. Therefore 4 command bits
and 12 data bits are used.
The following parameters and functional behavior can be
programmed by SPI:
Current regulation Mode (mode) : for each of the three
highside channels individually the operation mode can be
set. a) "no current regulation
b) Current regulation "hold only
c) Current regulation "peak & hold with minimum
peak time
d) Current regulation "peak & hold with pro-
grammed peak time".

SI command : 4 Command Bits program
the operation mode of Channels 1 to 6.
12 Data Bits configure the device and
give the input information (on or off) for
Channel 1 to 6.
SO diagnosis 16 bit diagnosis information
(two bit per channel) of channels 1 to 6 plus
two Overtemperature Flags
Peak Current (I_pk) : for each of the three highside channels individually the peak current value for P&H
current regulation can be programmed. The current range is 1.2A to 3.6A.
Fixed off time of the current regulator (t_fo) : for each of the three highside channels (Ch1 - Ch3) indi-
vidually the fixed off time for all modes with current regulation can be programmed from 100µs to
400µs.
Hold Current (I_hd) : for each of the three highside channels(Ch1 - Ch3) individually the hold current
value for P&H and hold only current regulation can be programmed. The current range is 0.7A to 2.0A
Peak Time (t_p) : for each of the three highside channels(Ch1 - Ch3) individually the peak time value for
P&H current regulation can be programmed. The time range is 0.8ms to 3.6ms.
Highside / Lowside Configuration ( H/L ) : Each of the three configurable channels (Ch4 – 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
three configurable channels(Ch4 – Ch6) the open load and switch bypassed diagnosis can be deacti-
vated. 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 pro-
grammed 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.
