dc-motor-control-btn8982ta's Introduction

DC-Motor-Control-BTN8982TA Library

Library of Infineon's DC motor control shield for Arduino.

Summary

The DC motor control shield is a high current motor control board being compatible to Arduino. It is capable to drive two uni-directional DC motors (half bridge configuration) or one bi-directional DC motor (H-Bridge configuration). The implemented integrated BTN8982TA NovalithIC™ half bridges can be controlled by a PWM via the IN Pin. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature, undervoltage, overcurrent and short circuit.

Key Features and Benefits

Compatible with Arduino Uno R3
Capable of high frequency PWM e.g. 30kHz
Adjustable slew rates for optimized EMI by changing external resistor
Driver circuit with logic level inputs
Diagnosis with current sense
Protection e.g. against overtemperature and overcurrent
Fast and inexpensive prototyping of DC motor control
Easy testing of half and full bridge motor control
Status flag diagnosis with current sense capability
Overtemperature shut down with latch behavior and undervoltage shut down

dc-motor-control-btn8982ta's Issues

Serial not working

On the XMC 1100 debug board the Bidirectional example sketch does not produce any Output. Changing the order of the begin calls of Serial and ifxMcsBiDirectionalMotor it works as expected.

I think the issue is that in the begin call of IfxMcsBiDirectionalMotor.cpp and IfxMcsUniDirectionalMotor.cpp respectively 'pinMode(mOut->pinIs, INPUT);' is called on an analog Pin which is not necessary. As A0 and A1 are defined as 0 and 1 it defines the pins 0 and 1 and thus rx and tx as input.

Unclear currentSense for PWM applications.

Following the application note "NovalithIC™ half-bridge family BTN89xx", the voltage at the IS pin should either be measured phased in the middle of the pwm duty cycle (Section 5.5) or lowpass filtered (Section 4.5.2.3). In this code the first option is not implemented and the shield proposed doesn't include a lowpass filter. The getCurrentSense method gives unreliable results to me.

Current Sense implementation?

Its unclear is current sense is actually implemented?? is there any example code on how to use this??
