DESCRIPTION
The VNH3ASP30-E is a full bridge motor driver
intended for a wide range of automotive
applications. The device incorporates a dual
monolithic High-Side drivers and two Low-Side
switches. The High-Side driver switch is designed
using STMicroelectronic’s well known and proven
proprietary VIPower™ M0 technology that allows
to efficiently integrate on the same die a true
Power MOSFET with an intelligent signal/
protection circuitry.
MultiPowerSO-30
The Low-Side switches are vertical MOSFETs
manufactured using STMicroelectronic’s
proprietary EHD (‘STripFET™’) process. 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 CS pin allows to monitor
the motor current by delivering a current
proportional to its value. The PWM, up to 20KHz,
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.
