Protection:
The TLE6288R has integrated protection functions
1
for overload and short circuit (active
current limitation), Overtemperature, ESD at all pins and overvoltage at the power outputs (zener
clamping).
Output Stage Control: Parallel Control and SPI Control
A Boolean operation (either AND or OR) is performed on each of the parallel inputs IN 1..6 and respec-
tive SPI data bits, in order to determine the states of the respective outputs. The type of Boolean op-
eration performed is programmed via the serial interface. Both, parallel inputs and respective SPI da-
tabits are high active.

Each output is independently controlled by an output latch and a common reset line FSIN, which dis-
ables all outputs. A logic high input ‘data bit’ turns the respective output channel ON, a logic low ‘data
bit’ turns it OFF.
Overtemperature Behavior:
Each channel has an overtemperature sensor and is individually protected against overtemperature.
As soon as overtemperature occurs the channel is immediately turned off. In this case here are two
different behavoirs of the affected channel that can be selected by SPI (for all channels generally).
Autorestart
: as long as the input signals of the channel remains on (e.g. parallel input high) the chan-
nel turns automatically on again after cooling down.
Latching
: After overtemperature shutdown the channel stays off until the this ovetemperature latch is
reset by a new L
H transition of the input signal.
Note: These overtemperature sensors of the channels are only active if the channel is turned on.
An additional overtemperature sensor is located in the logic of the device. I monitors permanently the
IC temperature. As soon as the IC temperature reaches a specified level an overtemperature fault will
be indicated.

Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault conditions are
considered as "outside" normal operating range. Protection functions are not designed for continuous repetitive operation
