Application Hints

Due to high peak output currents, the layout of the PC board is essential. Appropriate decou-

pling capacitors should be used, otherwise, the performance of the driver degrades severely. It

is strongly recommended to connect the blocking capacitors (low ESR types) as close as possi-

ble to the power supply and the ground pins. If necessary, two or more capacitors of different

types may be connected in parallel.

The two power ground pins, the ground pin, the two output pins and the two supply pins should

be externally connected together as close as possible to the pins.

The measurement pin (pin 5) and the test pin (pin 7) must not be used in any application and

need to be tied to ground.
