EVAL2293Q demonstration board pin location

The logic and power voltage supply pins are connected through jumper JP1 (normally

closed). If VS and VSS need to be supplied with different voltage values, JP1 should be

opened and the supply to each should be provided separately through external terminals.

The INx input pins drive the corresponding half-bridge. When a low logic level is applied, the

low side power switch is turned on, whereas a high logic level turns on the high side switch.

Pins EN1 and EN2 are used to disable the bridges and put the output pins in a high

impedance status. The output stages integrate freewheeling diodes.

Table 2 below summarizes the electrical specifications of the application, Figure 3 shows

the electrical schematic and Table 3 provides the component list.
