to T
MAX
, unless otherwise noted. Typical values are at T
A
= +25°C.)
Note 1: The voltage-detector output remains in the correct state for V
CC
down to 1.2V when V
IN
≤ V
CC
/ 2.
Note 2: Supply current has a monotonic dependence on V
CC
(see Typical Operating Characteristics ).
Note 3: IN leakage current has a monotonic dependence on V
CC
(see Typical Operating Characteristics ).
Note 4: The MAX834 open-drain output can be pulled up to a voltage greater than V
CC
, but may not exceed 11V.
