Attention:

The Schottky diode Ds should not be omitted if the local status outputs are used. If the

local status outputs are not used, LS1 should be connected to COM1 and LS2 to COM2

in order to increase the noise immunity of the driver.

Configuration within the Power Section

The drivers should be located as closely as possible to the power transistors. The

connecting leads to the transistors should be as short as possible and as low inductance

as possible, i.e. they can be up to 3cm to 10cm long depending on the gate current and

switching speed.
