Motor Control Shield with BTN8982TA

2 Motor Control Shield board description
1
For a safe and sufficient motor control design, discrete components are needed. Some of them must be
2
dedicated to the motor application and some to the NovalithIC™.
3
Figure 4, Figure 5 and Figure 6 show the schematics plus the corresponding layout of the Motor Control
4
Shield.
5
Due to the possibility of using the Shield with loads which can draw a current of up to 55 A the connectors
6
Vbat, GND, OUT1 and OUT2 are designed as solid 4mm through whole connectors. This provides the
7
possibility to connect plugs which are capable of such high currents. Nevertheless the thermal performance
8
of the Shield itself limits the possible current which should be applied to the Motor Control Shield to 30 A. To
9
reach the best performance in terms of parasitic inductance and EMC a GND plane, with maximal size was
10
designed.

2.1 Schematics
12
In Figure 4 the schematics of the Motor Control Shield is shown. The schematics are based on the
13
application circuit in the BTN8982TA Data Sheet.
