Smart 16-Channel Low-Side Switch

Electrical and Functional Description of Blocks

Power Outputs

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.

1) The integrated protection functions prevent an IC destruction under fault conditions and may not be used in normal

operation or permanently.
