MAX836/MAX837
4-Pin Micropower Voltage Monitors
ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VCC = +2.5V to +11.0V, TA= TMIN to TMAX, unless otherwise noted. Typical values are at TA= +25°C.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

NNoottee 11::The voltage-detector output remains in the direct state for VCC down to 1.2V when VIN ≤VCC/2.
NNoottee 22::Supply current has a monotonic dependence on VCC (see the
Typical Operating Characteristics
).
NNoottee 33::IN leakage current has a monotonic dependence on VCC (see the
Typical Operating Characteristics
).
NNoottee 44::The MAX836 open-drain output can be pulled up to a voltage greater than VCC, but may not exceed 11V.
