Figure 11. Functional Diagram of RESETIN Supervisory Application

RESETIN

The AS1910/AS1911/AS1912 feature a user-adjustable supervisory voltage input (RESETIN). The threshold voltage

for RESETIN is between 0.61 and 0.65V (0.63 typ).

Figure 12. Voltage Monitoring Circuit

To monitor a voltage higher than 0.63V, connect a resistor divider network to the circuit as shown in Figure 12. For the
