Operation Theory

4.2.1 Common Ground (Sinking Current)

To connect these signals, connect an external +5 V to +30 V

power supply to <VDDm>, connect <IGND> to ground, and cross

the load between <I_DOn> and <VDDm>. Please note that when

the load is of an “inductance nature” such as a relay, coil or motor,

the <VDDm> pin must be connected to external power supply. The

extra connection is utilized for the “fly-wheel diode” to form a cur

rent-release closed loop, so that the transistors are protected from

any high reverse voltage which can be generated by the induc

tance load when the output is switched from “ON” to “OFF”.
