Notes

9. Applies individually to each H-Bridge.

10. Average inductor current for DC/DC converter (connected between VDD and LX [L = 1.0 mH, C = 2.2 µF]).

11. Full drive (input signal to all input terminals).

12. The total H-bridge ON resistance when VG is 11.5 V.

13. When voltage is supplied externally without built-in DC/DC.

14. VIN is the voltage level applied to any input.
