Note 1: The voltage-detector output remains in the correct state for VCC down to 1.2V when VIN ≤ VCC / 2.
Note 2: Supply current has a monotonic dependence on VCC (see Typical Operating Characteristics).
Note 3: IN leakage current has a monotonic dependence on VCC (see Typical Operating Characteristics).
Note 4: The MAX834 open-drain output can be pulled up to a voltage greater than VCC, but may not exceed 11V.
