FULLY INTEGRATED H-BRIDGE MOTOR DRIVER

STMicroelectronics 

VNH3SP30

HALF-BRIDGE CONFIGURATION

The VNH3SP30 can be used as a high power half-bridge driver achieving an on resistance

per leg of 22.5mΩ. Suggested configuration is the following:

VCC

INA

INB

DIAGA/ENA

DIAGB/ENB

PWM

OUTA

OUTB

M

OUTA

IINNBA

DIAGA/ENA

DIAGB/ENB

PWM

OUTB

GNDA GNDB

GNDA GNDB

MULTI-MOTORS CONFIGURATION

The VNH3SP30 can easily be designed in multi-motors driving applications such as seat

positioning systems where only one motor must be driven at a time. DIAGX/ENX pins allow

to put unused half-bridges in high impedance. Suggested configuration is the following:

IINNAB

DIAGA/ENA

DIAGB/ENB

PWM

OUTA

OUTB

GNDA GNDB

VCC

M2
