Motor Control Shield with BTN8982TA for Arduino 1 About this document 2 Scope and purpose 3 This document describes how to use the Motor Control Shield with BTN8982TA for Arduino. 4 Intended audience 5 Engineers, hobbyists and students who want to add a powerful Motor Control to Arduino projects.
Motor Control Shield with BTN8982TA for Arduino 1 1 Motor Control Shield introduction 2 1.1 Motor Control Shield overview 3 4 5 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. 6 7 8 On board of the Motor Control Shield are two BTN8982TA NovalithICTM.

Motor Control Shield with BTN8982TA for Arduino 1 1.3 Block diagram of a bi-directional Motor Control 2 3 4 5 6 As a starting point for the Motor Control Shield, the application block diagram shown in Figure 3 was used. For simplicity reasons the conductivity L1 was removed in the Shield schematics. In the application block diagram the INH pins of both half-bridges are connected to one IO-port of the microcontroller.
Motor Control Shield with BTN8982TA for Arduino 1 2 Motor Control Shield board description 2 3 For a safe and sufficient motor control design, discrete components are needed. Some of them must be dedicated to the motor application and some to the NovalithIC™. 4 5 Figure 4, Figure 5 and Figure 6 show the schematics plus the corresponding layout of the Motor Control Shield.
Motor Control Shield with BTN8982TA for Arduino 1 2.2 Layout 2 3 Figure 5 and Figure 6 show the layout of the Motor Control Shield. The layout follows the design rules in the BTN8960 /62 /80 /82 High Current PN Half Bridge NovalithICTM Application Note (also see Chapter 2.3). 4 5 Figure 5 Motor Control Shield – Bottom and top layers Figure 6 Motor Control Shield for Arduino with BTN8982TA – Layout 6 7 Users Manual 8 V0.

Motor Control Shield with BTN8982TA for Arduino 1 2 3 4 5 6 C1/C3: This ceramic capacitors support C4 to keep the supply voltage ripple low and cover the fast transients between the Vs-pin and the GND-pin. The value of these ceramic capacitors must be chosen so that fast Vs-ripples at the NovalithIC™ do not exceed 1V peak to peak. The layout wiring for C1/C3 must be shorter than for C4 to the NovalithIC™ to keep the parasitic PCB-wire inductance as small as possible.

Motor Control Shield with BTN8982TA for Arduino 1 3 BTN8982TA overview 2 3 4 5 6 7 8 The BTN8982TA used in the Motor Control Shield is an integrated high current half-bridge for motor drive applications. It is part of the NovalithIC™ family containing one p-channel high side MOSFET and one nchannel low side MOSFET with an integrated driver IC in one package. Due to the p-channel high side switch the need for a charge pump is eliminated thus minimizing EMI.
Motor Control Shield with BTN8982TA for Arduino 1 3.2 Block diagram 2 3 4 5 6 The BTN8982TA is part of the NovalithIC™ family containing three separate chips in one package: One pchannel high side MOSFET and one n-channel low side MOSFET together with a driver IC, forming an integrated high current half-bridge. All three chips are mounted on one common lead frame, using the chip on chip and chip by chip technology.
