1 Motor Control Shield introduction
1
1.1 Motor Control Shield overview
2
The Motor Control Shield adds powerful motor control to the Arduino projects. The shield can be controlled
3
with the general logic IO-Ports of a microcontroller. Either an Arduino Uno R3 or the XMC1100 Boot Kit from
4
Infineon can be used as the master.
5
On board of the Motor Control Shield are two BTN8982TA NovalithIC
TM
. Each is featuring one P-channel high
6
side MOSFET and one N-channel low side MOSFET with an integrated driver IC in one package. Due to the P-
7
channel high side switch a charge pump is not needed.
8
The BTN8982TA half-bridge is easy to control by applying logic level signals to the IN and INH pin. When
9
applying a PWM to the IN pin the current provided to the motor can be controlled with the duty cycle of the
10
PWM. With an external resistor connected between the SR pin and GND the slew rate of the power switches
11
can be adjusted.
12
The Motor Control Shield can be easily connected to any Arduino board or the XMC1100 Boot Kit via
13
headers.

1.2 Key features
18
The Motor Control Shield has the following features:
19
 An Arduino Uno R3, XMC1100 Boot Kit, or similar board connected to the shield can control the two half-
20
bridges via the general IO pins.
