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 driver (HSD) and two low-

Datasheet - production data

side switches. The HSD switch is designed using

STMicroelectronics proprietary VIPower™ M0

technology that efficiently integrates a true Power

MOSFET with an intelligent signal/protection

circuit on the same die.

The low-side switches are vertical MOSFETs

manufactured using STMicroelectronics

proprietary EHD (“STripFET™”) process.The

three circuits are assembled in a

MultiPowerSO-30 package on electrically isolated

lead frames. This package, specifically designed

for the harsh automotive environment, offers

improved thermal performance thanks to exposed

die pads. Moreover, its fully symmetrical

mechanical design provides superior

manufacturability at board level. The input signals

INA and INB can directly interface with the

microcontroller to select the motor direction and

the brake condition. Pins 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. The CS pin monitors the motor current

by delivering a current proportional to its value.

The speed of the motor can be controlled in all

possible conditions by the PWM up to 20 kHz. 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.
