Description
The device is a full bridge motor driver intended
for a wide range of automotive applications. The
device incorporates a dual monolithic high-side
driver and two low-side switches.
Both switches are designed using
STMicroelectronics’ 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. The three dies are
assembled in SO-16N package on electrically
isolated leadframes.
Moreover, its fully symmetrical mechanical design
allows superior manufacturability at board level.
The input signals INA and INB can directly
interface the microcontroller to select the motor
direction and the brake condition. A SEL0 pin is
available to address the information available on
the MultiSense to the microcontroller. The
MultiSense pin allows to monitor the motor
current by delivering a current proportional to the
motor current value.
The PWM, up to 20 kHz, allows to control the
speed of the motor in all possible conditions. In all
cases, a low level state on the PWM pin turns off
both the LSA and LSB switches.
