DC Motor Control Shield with BTN8982TA

Hardware Compatible with Arduino

 

The DC motor control shield from Infineon technologies is one of the first high current motor control boards being compatible to Arduino as well as to Infineon’s XMC1100 Boot Kit. The DC motor control shield 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.

特征描述:

  • 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

优势:

  • 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

目标应用:

  • Brushed DC motor control up to 250W continuous load
    • 8–18V nominal input voltage (max. 6–40V)
    • Average motor current 30A restricted due to PCB (BTN8982 current limitation @ 55A min.)

How to drive easily small DC Motors with the new TLE94xyz Multi Half Bridges Family

www.infineon.com/multihalfbridges

The DC Motor Shield for Arduino comes with the TLE94112EL, the 1st device of the new protected TLE94xyz half-bridge drivers family.
Designed for small DC motors applications such as Heating, Ventilation, Air Conditioning (HVAC), as well as mirror adjustment and fold, the family offers 3-, 4-, 6-, 8-, 10-, and 12-fold integrated half-bridge driver. All devices can drive DC motor loads up to 0.9 A per output in cascaded or parallel operation. They provide diagnosis of short circuit, open load, power supply failure and overtemperature for each half-bridge to ensure safe operation in HVAC or other systems. The TLE94xyz offers enhanced EMC performance, which in combination with the low quiescent current and a small package makes the products attractive for automotive and other applications.
