Functional Description

General

ON state Low level at the input stage activates the output stage.

OFF state The internal pull-up resistor provides high level to the input comparator and deactivates the output stage.

A 7V Zener diode between input pin and GND is capable of ±10 mA clamping current.

Current Limitation of the Output Stages and Overtemperature Shutdown

A temperature-dependent current limitation in the range of 25 to 100 mA protects the stage in case of a short circuit. Additionally, the chip temperature is monitored. For TChip > 148°C, the output is disabled and automatically enabled with a hysteresis of TChip > 5°C.

Transients and Load Dump

An integrated 28V Zener diode protects the output stage against transients and load-dump Schaffner pulses . With the help of an external 1 resistor, the output transistor is capable of handling the corresponding current which flows during each of these conditions. Apart from that, the output is short-circuit and overload protected.
