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
