Description

The VNH5180A-E 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 PowerSSO-36 TP 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

and IN

can directly

interface to the microcontroller to select the motor

direction and the brake condition. The

DIAG

/EN

or DIAG

/EN

, when connected to an

external pull-up resistor, enables one leg of the

bridge. Each DIAG

/EN

provides a feedback

digital diagnostic signal as well. The normal

operating condition is explained in the truth table.

The CS pin allows to monitor the motor current by

delivering a current proportional to its value when

CS_DIS pin is driven low or left open. When

CS_DIS is driven high, CS 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 LS

and LS

switches.
