8.1.2 Multi-Purpose Sink Driver

TPL7407LA basic_application_SLRS073.gifFigure 8. Multi-Purpose Sink Driver Schematic

When configured as per Figure 8, the TPL7407LA may be used as a multi-purpose driver. The output channels may be tied together to sink more current. The TPL7407LA can easily drive motors, relays & LEDs with little power dissipation. COM must be tied to highest load voltage, which may or may not be same as inductive load supply.
