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 VIPower™ M0 technology that allows
to efficiently integrate on the same die a true
Power MOSFET with an intelligent signal/
protection circuitry.
MultiPowerSO-30
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
IN_A and IN_B can directly interface to the
microcontroller to select the motor direction and
the brake condition. The 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 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 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.
