Motor Control Shield for Arduino with BTN7030-1EPA

1 Motor Control Shield introduction

1.1 Motor Control Shield overview

The Motor Control Shield adds powerful motor control to the Arduino projects. The shield can be controlled
with the general logic IO-Ports of a microcontroller. Either an Arduino Uno R3 or the XMC1100 Boot Kit from
Infineon can be used as the master. Another way to control this board is via uIO Port using Infineon uIO Stick.

The device is a monolithic chip integrated in SMART7 technology. BTN7030-1EPA is a protected half-bridge with
integrated driver, providing protection and diagnosis functions. The high side power stage is built using a N­channel vertical power MOSFET with charge pump, while the low side power stage uses no charge pump. This
device has an exposed pad which ensures better cooling.

The BTN7030-1EPA half-bridge is easy to control by applying logic level signals to the IN and EN pin. When
applying a PWM to the IN pin the current provided to the motor can be controlled with the duty cycle of the
PWM. BTN7030-1EPA NovalithIC

1.2 Key features

The Motor Control Shield has the following features:

 An Arduino Uno R3 or XMC1100 Boot Kit can control the two BTN7030-1EPA devices via the general IO pins.
 6 – 18 V nominal input voltage (max. 3.8 – 28 V)
 Typical nominal current 7 A (current limitation is temperature dependent - 14 A @150ºC)
 Drives either one brushed bi-directional DC motor or two uni-directional DC motors.
 Capable of PWM up to 2 kHz
 Status flag diagnosis with current sense capability
 Current sense accuracy ~ 5%
 Protection against overtemperature, overcurrent, cross current, undervoltage
 Voltage clamping
 OFF state diagnosis (missing load and short circuit to battery or ground)

1.3 Block diagram of a full-bridge Motor Control

As a starting point for the Motor Control Shield, the application block diagram shown in Figure 2 was used. To
be flexible in the usage of the Motor Control Shield each IN, EN and DEN of the two half-bridges is connected to
a separate IO pin.
