Figure 13. Definition of delay response time of sense current
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:
Figure 14. Half-bridge 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
