MAX6808 - Maxim

MAX6808 Voltage Detectors

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 (VCC) falls below the factorypreset, ±2% accura.

Features

an active-low, push-pull RESET output; the MAX6807 features an active-high, push-pull RESET output; and the MAX6808 features an active-low, open-drain RESET output. RESET is valid for V CC down to 1V (MAX6806/ MAX6808), and RESET (MAX6807) is guaranteed for VCC down to 1.2V. The MAX6806/MAX6807/MAX6808 are available in 3-pin SC70, 3-pin SOT23, and 4-pin SOT143 packages. The SOT143 package includes a manual-reset input. Features o Preset Reset Thresholds: 4.6V and 2.6V (2.3V also available for MAX6806 only) o ±2% Accurate Reset Thresholds o Reset Output Available in Active-Low (MAX6806), Activ.
