FULLY INTEGRATED H-BRIDGE MOTOR DRIVER

STMicroelectronics 

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 INA and INB can directly

interface to the microcontroller to select the motor

direction and the brake condition. The DIAGA/ENA

or DIAGB/ENB, when connected to an external pull

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 LSA and LSB

switches. When PWM rises to a high level, LSA or

LSB turn on again depending on the input pin

state.
