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 IN_A and IN_B can directly
interface with the microcontroller to select the
motor direction and the brake condition. Pins
DIAG_A/EN_A or DIAG_B/EN_B, 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 LS_A and LS_B
switches. When PWM rises to a high level, LS_A or
LS_B turn on again depending on the input pin
state.
