Figure 5. Four power switching implementations
Power Switching Options
The figures below illustrate four possible methods for wiring the SMH4042. In the first example both power-FETs are
connected to a single VGATE output. This should be used when the design requires the backend voltages to be
powered-up simultaneously. In the second example both VGATE outputs are being used so that the 3.3V slew lags
the 5V slew. The two bottom circuits illustrate the wiring for single power supply boards. Note how the VSEL pin is
biased differently for the two applications.
