output toggles in one direction or the other. These
resistors are not required when using the MAX6338
because hysteresis is built into the device. MAX6338
hysteresis is typically 0.3%.
Undervoltage Detection Circuit
The open-drain outputs of the MAX6338 can be config-
ured to detect an undervoltage condition. Figure 2
shows a configuration where a low at a comparator out-
put indicates an undervoltage condition, which in turn
causes an LED to light.
Figure 5. Output Response of Window Detector Circuit
The MAX6338 can also be used in applications such as
system supervisory monitoring, multivoltage level
detection, and V CC bar graph monitoring (Figure 3).
Window Detection
A window detector circuit uses two auxiliary inputs in a
configuration such as the one shown in Figure 4.
External resistors R1–R4 set the two threshold voltages
(V TH1 and V TH4 ) of the window detector circuit. Window
width ( ? V TH ) is the difference between the threshold
voltages (Figure 5).
