consists of two DMOS transistors connected in
series with common drain to act as a switch with
the voltage applied in both direction. A charge
pump takes the gates of the DMOS above the
supply voltage. The motor is controlled by the
control ’logic low voltage’ block that receives the
motor status for the comparator.The ’charge C

block controls the T

Figure 2. Applicationschematicdiagram.
All the necessary external componentsare shown in the applicationdiagram. It is important to shunt the
motor with a devicethat limits the maximum over voltage to 40V. This is necessarywhen the power sup-
ply circuit is opened on motor power up. In this case the back E.M.F. must be clamped becausethere is
no otherfree wheel current path.
