Description

The VNH3SP30-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-

side switches. The HSD switch is designed using

STMicroelectronics proprietary VIPower™ M0-3

technology that efficiently integrates a true Power

MOSFET with an intelligent signal/protection

circuit on the same die.

MultiPowerSO-30™

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 speed of the motor can be

controlled in all possible conditions by the PWM

up to 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.
