When D1 is logic HIGH, both OUT1 and OUT2 are tri-stated. Schmitt trigger
input with ~80 μA source so default condition = disabled.
The load current feedback output provides ground referenced 0.24% of the high
side output current. (Tie to GND through a resistor if not used.)
When EN/D2 is logic HIGH the H-bridge is operational. When EN/D2 is logic
LOW, the H-bridge outputs are tri-stated and placed in Sleep mode. (logic input
with ~ 80 μA sink so default condition = Sleep mode.)
These pins must be connected together physically as close as possible and
directly soldered down to a wide, thick, low resistance supply plane on the PCB.
Source of high side MOSFET1 and drain of low side MOSFET1.
High-current power ground pins must be connected together physically as
close as possible and directly soldered down to a wide, thick, low resistance
ground plane on the PCB.
Source of high side MOSFET2 and drain of low side MOSFET2.
