excessive voltage spikes caused by bridge operation and place a 100 nF or larger filter capacitor to
GND close to the VS pin.
Attention
Keep supply voltage ripple low, by using sufficient filtering capacity (ceramic capacitors plus low ESR
electrolytic) close to the MOSFET bridge. Place the ceramic capacitors directly left and right of the IC
package, e.g. 2.2µF types.
