Abstract: A switching element driver IC has one or more photocouplers, a driver circuit, a detection circuit and a setting circuit. The photocoupler receives setting data transmitted from a microcomputer, and transmits the received setting data to the setting circuit, wherein an input side as a high voltage side is electrically insulated from an output side as a low voltage side in the photocoupler. The setting circuit transmits the setting data to the driver circuit and the detection circuit. The driver circuit and the detection circuit operate on the basis of the received setting data. The setting data can be provided to the driver circuit and the detection circuit through the photocoupler and the setting circuit. This structure makes it possible to suppress increasing the number of terminals at the high voltage side of the switching element driver IC, and decrease the entire size of the switching element driver IC.

Abstract: In a driver, a clamping module executes a clamping task that clamps an on-off control terminal voltage to be equal to or lower than a clamp voltage for a predetermined time during charging of the on-off control terminal of the switching element. The clamp voltage is lower than an upper limit of the voltage at the on-off control terminal of the switching element. A measuring module measures a parameter value correlated with a sense current correlated with a current flowing between input and output terminals of the switching element. A limiting module discharges the on-off control terminal to limit flow of the current between the input and output terminals if the value of the parameter exceeds a threshold. A setting module variably sets a length of the predetermined time as a function of the parameter value during charging of the switching element's on-off control terminal.
