TLE6240GP
Smart 16-Channel Low-Side Switch
Control of the Device
To drive all 16 channels and to get the complete diagnosis data of the TLE6240GP a two step access has to be
performed as follows:
CS
SI Control Byte1 Data Byte1
SO
16 bit Diagnosis
SI command: Control Byte 1 programs the
operation mode of channels 1 to 8.
Data Byte 1 gives the input information (on
or off) for Channel 1 to 8.
SO diagnosis: Diagnosis information of
channel 1 to 8 or 9 to 16, depending on the
SI control word before.

CS
SI Control Byte1 Data Byte1
SO
DIAG_1 (Ch. 1 to 8)
SI command: Control Byte 1 programs the
operation mode of Channels 1 to 8.
Data Byte 1 gives the input information (on
or off) for Channel 1 to 8.
SO diagnosis: 16 bit diagnosis information
(two bit per channel) of channels 1 to 8
CS
SI Control Byte2 Data Byte2
SO
16 bit Diagnosis
SI command: Control Byte 2 programs the
operation mode of channels 9 to 16.
Data Byte 2 gives the input information (on
or off) for Channel 9 to 16.
SO diagnosis: Diagnosis information of
channel 1 to 8 or 9 to 16, depending on the
SI control word before.

CS
SI Control Byte2 Data Byte2
SO
DIAG_2 (Ch. 9 to 16)
SI command: Control Byte 2 programs the
operation mode of Channels 9 to 16.
Data Byte 2 gives the input information (on
or off) for Channel 9 to 16.
SO diagnosis: 16 bit diagnosis information
(two bit per channel) of channels 9 to 16
