20.1.1 Supply Voltage Sequencing and Separation Cautions
Figure 20-1 shows two situations to avoid in sequencing the IV
IV

(Figure 20-2). This keeps IV
IV
supplies (2). Typically this situation is avoided by using external discrete diodes in series
between supplies as shown in Figure 20-2. The series diodes forward bias when the
difference between EV
ramps up. When the IV
should not exceed 1.5 V and conduction through the diode chain reduces to essentially
leakage current. During supply sequencing, the following general relationship should be
adhered to: EV
