Voltage Detectors
General Description
The MAX6806/MAX6807/MAX6808 precision voltage
detectors are ideal for accurate monitoring of power
supplies in digital systems. They provide circuit reliabili-
ty and reduce total cost by eliminating external compo-
nents 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 fea-
tures 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 out-
put. 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.
