Motor Control Shield with BTN8982TA
for Arduino
Users Manual 12 V0.9, 2015-03
3 BTN8982TA overview
1
The BTN8982TA used in the Motor Control Shield is an integrated high current half-bridge for motor drive
2
applications. It is part of the NovalithIC™ family containing one p-channel high side MOSFET and one n-
3
channel low side MOSFET with an integrated driver IC in one package. Due to the p-channel high side switch
4
the need for a charge pump is eliminated thus minimizing EMI. Interfacing to a microcontroller is made easy
5
by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate
6
adjustment, dead time generation and protection against overtemperature, undervoltage, overcurrent and
7
short circuit.
8
The BTN8982TA provides a cost optimized solution for protected high current PWM motor drives with very
9
low board space consumption.
