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

Note 1: Devices are production tested at TA = +25°C. Overtemperature limits are guaranteed by design.
Note 2: IN voltage monitoring requires that VCC ≥ 4V, but OUT remains asserted in the correct undervoltage lockout state for VCC
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 VCC but cannot exceed +28V.
ELECTRICAL CHARACTERISTICS (continued)
(VCC = 4V to 28V, TA = -40°C to +125°C, unless otherwise specified. Typical values are at TA = +25°C.) (Note 1)
