VNH3ASP30-E
Figure 12. Half-bridge Configuration
The VNH3ASP30-E can be used as a high power half-bridge driver achieving an ON
resistance per leg of 22.5mΩ. Suggested configuration is the following:
INA
INB
DIAGA/ENA
DIAGB/ENB
PWM
OUTA
OUTB
GNDA GNDB
VCC

Figure 13. Multi-motors Configuration
The VNH3ASP30-E 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:
INA
INB
DIAGA/ENA
DIAGB/ENB
PWM
OUTA
OUTB
GNDA GNDB
