NON-MASKABLE INTERRUPT Figure 6

DS1236A

EXAMPLE 1: 5-VOLT SUPPLY, R2 = 10k OHM, VSENSE = 4.80 VOLTS

â´

4.80 =

R1 + 10k

10k

X 2.54

R1 = 8.9k OHM

EXAMPLE 2: 12-VOLT SUPPLY, R2 = 10k OHM, VSENSE = 9.00 VOLTS

â´

9.00 =

R1 + 10k

10k

X 2.54

R1 = 25.4k OHM

VMAX =

9.00

2.54

X 5.00 = 17.7 VOLTS
