The MAX6806/MAX6807/MAX6808 precision voltage detectors are ideal for accurate monitoring of power supplies in digital systems. They provide circuit reliability and reduce total cost by eliminating external components and adjustments.

The MAX6806/MAX6807/MAX6808 assert a reset signal whenever the supply voltage (V_CC) falls below the factory-preset, ±2% accurate threshold. Internal hysteresis ensures stable switching. The MAX6806/MAX6807/MAX6808 are available in 4.6V and 2.6V thresholds (2.3V is also available for the MAX6806 only). The MAX6806 features an active-low, push-pull RESET-bar output; the MAX6807 features an active-high, push-pull RESET output; and the MAX6808 features an active-low, open-drain active-low RESET output. active-low RESET is valid for V_CC down to 1V (MAX6806/MAX6808), and RESET (MAX6807) is guaranteed for V_CC down to 1.2V.

The MAX6806/MAX6807/MAX6808 are available in 3-pin SC70, 3-pin SOT23, 8-pin µMAX®, 8-pin SO, and 4-pin SOT143 packages. The SOT143 package includes a manual-reset input.
