Abstract

Provided is an ink jet head drive circuit that prevents unintentional invalidation of a protection function. The ink jet head drive circuit according to an embodiment includes a drive unit configured to drive an actuator, a protection circuit configured to execute a protection function of the inkjet head drive circuit, and a setting data register configured to store setting data including multi-bit designation data designating validation or invalidation of the protection function and to output the multi-bit designation data to the protection circuit. The protection circuit invalidates the protection function only when bit values of the multi-bit designation data match bit values of multi-bit invalidation designation data designating the invalidation of the protection function. The protection circuit validates the protection function when the bit values of the multi-bit designation data do not match the bit values of the multi-bit invalidation designation data.
