The Infineon OPTIREG™ Trackers are specially designed to supply the off-board sensors. High voltage accuracy and robustness of device implementation are the key benefits of Infineon voltage trackers. All voltage tracker products implement various protection features , such as: Over-Voltage, Over-Temperature, Reverse-Polarity and Reverse-Current . Together with robust design implementation and AECQ100 grade package voltage tracker are perfect solution to protect sensor and ECU in harsh environment. Also voltage output monitoring diagnostic is available on some products. This enables a significantly easier and faster way to detect an over or under-voltage and react accordingly and record such event.
Examples for typical fault conditions handled efficiently with Infineon voltage tracker:
- In case of a short circuit to GND on the external wire, the current flowing through the power stage is limited by the current limitation circuitry. This limits stress condition on primary supply and protects ECU from the overload.
- In case of a short circuit to the battery voltage on the wire, the voltage tracker is in reverse polarity condition. The reverse current through the tracker is limited by the reverse polarity protection. Again ECU is protected from damage.
