Notes

Applies individually to each H-Bridge.

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

10.

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

11.

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

12.

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

13.

VIN is the voltage level applied to any input.
