VNH3SP30
The three dice are assembled in MultiPowerSO-30
package on electrically isolated leadframes. This
package, specifically designed for the harsh
automotive environment offers improved thermal
performance thanks to exposed die pads.
Moreover, its fully symmetrical mechanical design
allows superior manufacturability at board level.
The input signals IN

up resistor, enable one leg of the bridge. They also
provide a feedback digital diagnostic signal. The
normal condition operation is explained in the truth
table on page 7. The PWM, up to 10KHz, lets us to
control the speed of the motor in all possible
conditions. In all cases, a low level state on the
PWM pin will turn off both the LS
A
and LS
B
switches. When PWM rises to a high level, LS
A
or
LS
B
turn on again depending on the input pin
state.
