3-Pin, Ultra-Low-Power SC70/SOT23
Voltage Detectors
The MAX6377/MAX6380 have an active-low, open-
drain output. This output structure sinks current when
OUT is asserted. Connect a pullup resistor from OUT to
any supply voltage up to 5.50V (Figure 1). Select a
resistor value large enough to allow a valid logic low
(see Electrical Characteristics), and small enough to
register a logic high while supplying all input current
and leakage paths connected to the OUT line.

These devices are relatively immune to short-duration,
negative-going V
Operating Characteristics show the Maximum Transient
Duration vs. Threshold Overdrive graph, for which out-
put pulses are not generated. The graph shows the
maximum pulse width that a negative-going V
sient may typically have before the devices issue out-
put signals. As the amplitude of the transient increases,
the maximum-allowable pulse width decreases.
