Description
The VNH5050A-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. All switches are designed using
STMicroelectronics® well known and proven
PowerSSO-36 TP
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 a PowerSSO-36 TP package on
electrically isolated lead frames. 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, enables one leg of the bridge.
Each DIAGA/ENA provides a digital diagnostic
feedback signal as well. The normal operating
condition is explained in the truth table. The CS
pin allows monitoring 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 LSA and LSB
switches.
