DESCRIPTION
The VNH2SP30-E is a full bridge motor driver
intended
for
a
wide
range
of
automotive
applications. The device incorporates a dual
monolithic High-Side drivers and two Low-Side
switches. The High-Side driver switch is designed
using STMicroelectronic’s well known and proven
proprietary VIPowerM0 technology that allows
to efficiently integrate on the same die a true
Power
MOSFET
with
an
intelligent
signal/
protection circuitry.
Figure 1. Package
The Low-Side switches are vertical MOSFETs
manufactured
using
STMicroelectronic’s
proprietary EHD (‘STripFET™’) process.The three
dice are assembled in MultiPowerSO-30 package
on electrically isolated leadframes. This package,
specifically designed for the harsh automotive
environment offers improved thermal performance
thanks to exposed die pads. Moreover, its fully
symmetrical mechanical design allows superior
manufacturability at board level. The input signals
INA and INB can directly interface to the
microcontroller to select the motor direction and
the brake condition. The 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 truth
table on page 14. The CS pin allows to monitor the
motor current by delivering a current proportional
to its value. The PWM, up to 20KHz, lets us to
control the speed of the motor in all possible
conditions. 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.
