Abstract
To provide a technique to complement overcurrent protection and short circuit protection. An LVIC includes an overcurrent detector configured to detect whether or not a first current flowing through a load and a semiconductor switching element is abnormal and a short-circuit detector configured to detect whether or not a second current flowing not through the load but through the semiconductor switching element is abnormal. The LVIC interrupts the semiconductor switching element based on a detection result of the overcurrent detector and a detection result of the short-circuit detector.
Claims8
A driving device configured to drive a semiconductor switching element connecting to a load, comprising:
- an overcurrent detector configured to detect whether or not a first current flowing through the load and the semiconductor switching element is abnormal;
- and
- a short-cut detector configured to detect whether or not a second current flowing not through the load and but through the semiconductor switching element is abnormal, wherein
- based on a detection result of the overcurrent detector and a detection result of the short-circuit detector, the semiconductor switching element is interrupted.
