Effect of Temperature on Timeout

Period (tRPU)

The timeout period (tRPU) determines how long the

device remains in the reset condition. This is controlled

by an internal RC timer and is effected by both VDD and

temperature. The graph shown in Figure 2-3 shows

typical response for different VDD values and tempera-

tures.
