ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: Devices are production tested at +25°C. Overtemperature limits are guaranteed by design.
Note 2: IN voltage monitoring requires that V
Note 3: Startup time is the time required for the internal regulator and reference to reach specified accuracy after the monitor is
Note 4: The open-drain output can be pulled up to a voltage greater than V
