Driver characteristics evaluation method for IC driver circuit

摘要

.The driver characteristics evaluation method is effected by bringing a capacitance (C1) connected to the output (OUT) of the driver circuit (DRV) to a given potential, with activation of the driver circuit at a given test point, so that a current flows between the output and the capacitance. This current is interrupted at a second time point and the potential at the capacitance measured and evaluated as a measure of the driver characteristics. The capacitance may be set initially to earth potential, with subsequent measurement of the capacitance potential via an evaluation stage (INV,COMP) within the IC.
