Input 2
Definition
Logic input control of OUT2; e.g., when IN2 is logic HIGH, OUT2 is set to V PWR ,
and when IN2 is logic LOW, OUT2 is set to PGND. (Schmitt trigger input with
~ 80 μ A source so default condition = OUT2 HIGH.)
2
IN1
Logic Input
Input 1
Logic input control of OUT1; e.g., when IN1 is logic HIGH, OUT1 is set to V PWR ,
and when IN1 is logic LOW, OUT1 is set to PGND. (Schmitt trigger Input with
~ 80 μ A source so default condition = OUT1 HIGH.)
3
SLEW
Logic Input
Slew Rate
Logic input to select fast or slow slew rate. (Schmitt trigger input with ~ 80 μ A
sink so default condition = slow.)

These pins must be connected together physically as close as possible and
Supply
directly soldered down to a wide, thick, low resistance supply plane on the PCB.

Logic Input
Analog Signal
Ground
Input Invert
The low current analog signal ground must be connected to PGND via low
impedance path (<<10 m Ω , 0 Hz to 20 kHz). Exposed copper pad is also the
main heatsinking path for the device.
Sets IN1 and IN2 to logic LOW = TRUE. (Schmitt trigger input with ~ 80 μ A sink
so default condition = non-inverted.)

FB
Analog
Feedback
Load current feedback output provides ground referenced 0.24% of H-Bridge
Output
high-side output current. (Tie pin to GND through a resistor if not used.)

NC
No Connect
No internal connection is made to this pin.
10
EN
Logic Input
Enable Input
When EN is logic HIGH, the device is operational. When EN is logic LOW, the
device is placed in Sleep mode. (logic input with ~ 80 μ A sink so default
condition = Sleep mode.)
