operates properly in the application, the current in the Zener diode has to be limited by a ground resistor.
shows a typical application to withstand overvoltage issues. In case of supply voltage higher than
transistor switches ON and the voltage across the logic section is clamped. As a result, the internal ground
potential rises to
to that potential, depending on the impedance of the connected circuitry. In the case the device was ON, prior to
overvoltage, the BTS5020-2EKA remains ON. In the case the BTS5020-2EKA was OFF, prior to overvoltage, the
power transistor can be activated. In the case the supply voltage is in above
transistor is still operational and follows the input. If at least one channel is in the ON state, parameters are no
longer guaranteed and lifetime is reduced compared to the nominal supply voltage range. This especially impacts
the short circuit robustness, as well as the maximum energy
superior results compared to a diode and resistor (1 kΩ).
