6.2
Due to the fast switching times for high currents, special care has to be taken to the PCB layout. Stray inductances
have to be minimized in the power bridge design as it is necessary in all switched high power bridges. The
BTN7960 has no separate pin for power ground and logic ground. Therefore it is recommended to assure that the
offset between the ground connection of the slew rate resistor, the current sense resistor and ground pin of the
device (GND / pin 1) is minimized. If the BTN7960 is used in a H-bridge or B6 bridge design, the voltage offset
between the GND pins of the different devices should be small as well.
A ceramic capacitor from VS to GND close to each device is recommended to provide current for the switching
phase via a low inductance path and therefore reducing noise and ground bounce. A reasonable value for this
capacitor would be about 470 nF.
The digital inputs need to be protected from excess currents (e.g. caused by induced voltage spikes) by series
resistors in the range of 10 kΩ.
