The VNH5019A-E can be used as a high power half-bridge driver achieving an
on- resistance per leg of 9.5 mΩ. The figure below shows the suggested configuration:

The VNH5019A-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. DIAG_X/EN_X pins allow
to put unused half-bridges in high-impedance. The figure below shows the suggested
configuration:
