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.

Name
Description
Logic control
Allows the turn-on and the turn-off of the high side and the low side switches
according to the truth table
Overvoltage +
undervoltage
Shuts down the device outside the range [5.5V..36V] for the battery voltage
High side and low Protects the high side and the low side switches from the high voltage on the
side clamp voltage battery line in all configurations for the motor
High side and low
side driver
Drives the gate of the concerned switch to allow a proper RDS(on) for the leg of
the bridge
Linear current limiter
Limits the motor current by reducing the high side switch gate-source voltage
when short-circuit to ground occurs
Overtemperature
protection
Fault detection
In case of short-circuit with the increase of the junction’s temperature, shuts
down the concerned high side to prevent its degradation and to protect the die
Signals an abnormal behavior of the switches in the half-bridge A or B by
pulling low the concerned ENx/DIAGx pin
