Electrical and Functional Description of Blocks

Power Outputs
Power Transistor Protection Functions¹⁾
Each of the 16 output stages has its own zener clamp, which causes a voltage limitation at the power transistor
when solenoid loads are switched off. The outputs are provided with a current limitation set to a minimum of 1 A
for channels 1 to 8 and 3 A for channels 9 to 16.
In the event of an overload or short to supply, the current is internally limited and the corresponding diagnosis bit
combination is set. If this operation leads to an overtemperature condition, a second protection level will change
the output into a low duty cycle PWM (selective thermal shut-down with restart) to prevent critical chip
temperatures.
