All logic pins have ESD protection. Beside the output clamp for the power stage as described in
is a clamp mechanism implemented for pin IS. See

In case of complete loss of the device ground connections the BTS50080-1EGA securely changes to or remains
in OFF state, if the sense resistor

In case of loss of load with charged primary inductances the maximum supply voltage has to be limited. It is
recommended to use a Z-diode, a varistor ( V

For higher clamp voltages currents through all pins have to be limited according to the maximum ratings. Please
