摘要: An object of the present invention is to provide a current detection circuit for power semiconductor device, having small scale and number parts, generating amount losses. The executes utilizing sense function device. unknown magnitude flowing in devices 1, 11 detected by current-voltage conversion 24 connecting terminals S, S devices. signal delivered direction 27, which detects delivers an external CPU 3, turn gives gain-setting offset-setting signals corresponding signal. output gain adjuster 221 adjusts offset 231 execute correction difference between characteristics region main region.
