High-Voltage, Low-Current Voltage Monitors in
SOT Packages
_______________________________________________________________________________________

Note 1:
Devices are production tested at +25
°
C. Overtemperature limits are guaranteed by design.
Note 2:
IN voltage monitoring requires that V
CC
≥
4V, but OUT remains asserted in the correct undervoltage lockout state for V
CC
down to 1.5V.
Note 3:
Startup time is the time required for the internal regulator and reference to reach specified accuracy after the monitor is
powered up from GND.
Note 4:
The open-drain output can be pulled up to a voltage greater than V
CC
but cannot exceed +28V.
