Product overview

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. All 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 dice are assembled in a PowerSSO-36 package equipped with three exposed islands for optimized dissipation performances. This package is specifically designed for the harsh automotive environment and offers improved thermal performance thanks to exposed die pads. A Multisense_EN pin is available to enable the MultiSense diagnostic. The input signals INA and INB can directly interface the microcontroller to select the motor direction and the brake condition. Two selection pins (SEL0 and SEL1) are available to address to the microcontroller the information available on the Multisense. The Multisense pin allows to monitor the motor current by delivering a current proportional to the motor current value and provides also the diagnostic feedback according to the implemeted truth table. When MultiSense_EN pin is driven low, MultiSense pin is in high impedance condition. 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.
