PIN CONNECTIONS
24
RS
Slew Rate Control
This input pin is connected to a resistor that sets slew timing.
25
PWM
PWM Input
This input pin is used to set the motor switching and frequency duty cycle.
26
FWD
Forward Input
This input pin, along with the reverse input pin REV, determines the direction of
current flow in the H-Bridge.
27
REV
Reverse Input
This input pin, along with the forward input pin FWD, determines the direction of
current flow in the H-Bridge.
28
VCCL
3.3 V Input

Tab/Pad
Thermal
Interface/
GND
Exposed Pad Thermal
Interface
The exposed pad, a thermal interface for sinking heat from the device, is also a
high-current GND connection and must be connected to GND (pins 12 and 19).
