ÿ DC Motor Full Bridge Driver / Controller
The E910.64/65 is a PWM DC Motor Bridge Controller to drive ex-
ÿ Single voltage supply in the range of
ternal N-channel power-FETs in a full bridge or double independ-
Vbat = 6.0V to 40V
ent half bridge configuration. The IC is designed for motor appli-
ÿ Sleep mode current less than 50μA
cations in the automotive world as well as for general purposes.
ÿ High power efficiency of the whole motor regulator A digital algorithm for EMC optimation is implemented to reduce
system (up to 96% @ fPWM = 20kHz)
the generation of high frequency oscillations. The E910.64/65 fea-

With the EMC Performance the module developer will be able
to save additional filter components in the power lines by driv-
application
ing a DC motor. Via SPI access it is possible to get data related to
ÿ Electro-Hydraulic Power steering
the diagnosis, treatment of motor and the Power FET failures.
ÿ Parking brakes
The IC is able to detect and to handle the follwing failures such
ÿ Closure Systems
as over current, short circuit, open load, over/under voltage and
ÿ Wiper Systems
over temperature. A K-Line or LIN 2.0 Interface connects the ap-
plication to the bus system. There are two versions both with
supply voltages up to 40V : E910.64 delivered in SO20 package and
E910.65 delivered in SO24 package.
