DESCRIPTION
Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transients compatibility table). Active current limitation combined with thermal shutdown protect the device against BLOCK DIAGRAM overload. After a thermal shutdown event, device stays latched off and diagnostic stays at a low level until next falling edge of input signal. Output shorted to VCC is detected in the off state. Device automatically turns off in case of ground pin disconnection. Enable pin allows to switch the device to idle state with very low quiescent current from VCC. When enable is low, device turns off regardless of input pin state.
