VNH3SP30-E
Automotive fully integrated H-bridge motor driver
Datasheet - production data
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 lowside 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.

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 pullup resistor, enable one leg of the bridge. They
also provide a feedback digital diagnostic signal.
The normal operating conditions are explained in
the truth table. 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 will turn on again depending on the state of
the input pin.
