CIRCUIT DESCRIPTION
The IL9001 is a monolithic full bridge switching motor driver realized in the new Mul-tipower-BCD technology
which allows the integration of multiple, isolated DMOS power transistors plus mixed CMOS/bipolar control
circuits. In this way it has been possible to make all the control inputs TTL, CMOS and C compatible and
eliminate the necessity of external MOS drive components. The Logic Drive is shown in table 1.

Although the device guarantees the absence of cross-conduction, the presence of the intrinsic
diodes in the POWER DMOS structure causes the generation of current spikes on the sensing
terminals. This is due to charge-discharge phenomena in the capacitors C1 & C2 associated with
