The adjustable voltage monitor is comparable to an
internal reference of 1.23V as shown in Figure 6. To set
the desired trip level of monitored supply, V
choose: R1 = R2 [(V
voltage detection at 4.5V (assume R2 = 100k ), R1 =
265k .

The unused inputs (except the auxiliary) are internally
connected to ground through the lower resistors of the
threshold-setting resistor pairs. The auxiliary (AUX)
input, however, must be connected to either ground or
V
The MAX6338 operates from a single +2.5V to +5.5V
supply. In noisy applications, connect a 0.1µF capaci-
tor on the supply voltage line close to V
bypassing.
