Description
The VNH3ASP30-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
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 IN
A
and IN
B
can directly
interface with the microcontroller to select the
motor direction and the brake condition. Pins
DIAG
A

A
or DIAG

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 Table 12: Truth table in normal
operating conditions on page 14. The CS pin
monitors the motor current by delivering a current
proportional to its value. The speed of the motor
can be controlled in all possible conditions by the
PWM up to 20 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.
