D1

Logic Input

Disable Input 1

(Active High)

When D1 is logic HIGH, both OUT1 and OUT2 are tri-stated. Schmitt trigger

input with ~80

μA source so default condition = disabled.

FBA

Analog

Output

Feedback

H-Bridge A load current feedback output provides ground referenced 0.24% of

the high side output current. (Tie to GND through a resistor if not used.)

3

EN/D2

Logic Input

Enable Input

When EN/D2 is logic HIGH, H-Bridge A is operational. When EN/D2 is logic

LOW, the H-Bridge A outputs are tri-stated and H-bridge A is placed in Sleep

Mode. (logic input with ~80

μA sink so default condition = Sleep Mode.)

Power Input

Positive Power

Supply

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.

OUT1

Power

Output

H-Bridge Output 1

H-bridge A source of high side MOSFET1 and drain of low side MOSFET1.

Power Ground

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.
