DC Motor Control Shield
with BTN8982TA for Arduino
The DC Motor Control Shield from Infineon is one of the first high-current motor control
boards being compatible to Arduino as well as to Infineon’s XMC1100 Boot Kit. It is capable
of driving two uni-directional DC motors (half bridge configuration) or one bi-directional
DC motor (H-Bridge configuration).
The implemented NovalithIC™ integrated half-bridge driver BTN8982TA 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 adjust-
ment, dead time generation and protection against overtemperature, undervoltage,
overcurrent and short circuit.
Applications

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
(BTN8982TA current limitation @ 55A min.)
