APPLICATION EXAMPLE
SG1548/SG2548/SG3548
In this example, the SG1548 simultaneously monitors four DC voltages: +5V, +24V, and ±15V. Three different fault tolerances are
programmed: ±5% on the two 15V supplies, ±10% on the +5V supply, and ±20% on the +24V supply. The 5µF delay capacitor provides
125 milliseconds of fault delay.
