10.Applications

The following sections introduce the basic typical application of BASiC driver ICs, which is for reference only. In practical

application, users need to verify and test its applicability according to their own design requirements to confirm the sys-

tem functions.

10.1TypicalApplications

BASiC recommends that customers add a RC filter with a small time constant at the input port to filter out high-fre-

quency interference without adding a large delay. It is recommended that the resistance value should be be-tween 0

and 100Ω and the capacitance should be less than 1000pF. When setting this parameter, the influence between high fre-

quency interference and delay needs to be taken into account.

To ensure the supply stability, BASiC recommends to add appropriate blocking capacitor between the power supply

and ground. It is recommended to parallel a 1uF+ 0.1uF capacitor between VCC1-GND1, and a 10uF+ 0.22uF capacitor

between VCC2-VEE2 (Figure 11,12,13).
