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.

Block diagram and pins description
Table 4. Pin functions description
Name
Description
VCC Battery connection
GNDA, GNDB Power grounds; must always be externally connected together
OUTA, OUTB Power connections to the motor
INA, INB
Voltage controlled input pins with hysteresis, CMOS compatible. These two pins
control the state of the bridge in normal operation according to the truth table (brake
to VCC, brake to GND, clockwise and counterclockwise).
PWM
Voltage controlled input pin with hysteresis, CMOS compatible. Gates of low side
FETs are modulated by the PWM signal during their ON phase allowing speed
control of the motor.
ENA/DIAGA,
ENB/DIAGB
Open drain bidirectional logic pins. These pins must be connected to an external pull
up resistor. When externally pulled low, they disable half-bridge A or B. In case of
fault detection (thermal shutdown of a high side FET or excessive ON state voltage
drop across a low side FET), these pins are pulled low by the device (see truth table
in fault condition).
