Direction indicator circuit for controlling a direction indicator in a vehicle

A direction indicator circuit for controlling a direction indicator in a vehicle, the direction indicator circuit comprising:

• a first terminal for connecting to a supply voltage;
• a second terminal for connecting to a direction indicator switch and a lighting means;
• a third terminal for connecting to a capacitor;
• and
• a switch for providing a current, wherein the switch is connected to the first terminal and to the second terminal;
• wherein the direction indicator circuit is designed to provide the lighting means with a current during an on state using the switch and with no current during an off state;
• wherein during the on state the direction indicator circuit checks the provided current at least once and goes into the off state if the check detects a current which is lower than a predefined current;
• wherein the direction indicator circuit checks the voltage present at the switch and then checks a provided current if the voltage check detects a voltage lower than a predefined switch voltage.

A direction indicator circuit for controlling a direction indicator in a vehicle, the direction indicator circuit comprising:

• a first terminal directly connected to a supply voltage;
• a second terminal for connecting to a direction indicator switch and a lighting means;
• a third terminal for connecting to a capacitor;
• wherein the third terminal is directly connected to the first terminal;
• and
• a p-channel metal oxide semiconductor field effect transistor switch for providing a current, wherein the switch is directly connected to the first terminal and to the second terminal;
• wherein the direction indicator circuit is designed to provide the lighting means with a current during an on state using the switch and with no current during an off state;
• wherein during the on state the direction indicator circuit checks the provided current at least once and goes into the off state if the check detects a current which is lower than a predefined current.
