Output device control circuit and power device circuit

A power device control circuit (200) outputs a gate drive signal in a gate terminal (100a) one of a power device (100). The power device control circuit (200) includes: a control signal input circuit (2) including a power device control signal (1a) for controlling the power device (100) receives; a driving system control circuit (4) connected to the control signal input circuit (2) is connected; a drive circuit (5) having a plurality of driving systems, wherein the drive circuit (5), the power device (100) controls received in response to a driving system of the control circuit (4), driving circuit control signal (1c); and a timer circuit (3), which switches in response to the driving circuit control signal (1c) between the driving systems after a given period of time after receiving a predetermined signal, or more precisely of the power device control signal 1a has elapsed, whereby the driving power of the Ansteuersystem- control circuit (4) for driving the power device (100) is changed.
