General Description
The MAX6886 pin-selectable, multivoltage supply
supervisor monitors six voltage-detector inputs and one
watchdog input, asserting a RESET when inputs drop
below the selected voltage thresholds or the watchdog
timer expires. Manual reset and margin disable inputs
offer additional flexibility.
Five logic inputs select the MAX6886 thresholds. Logic
inputs select a supply tolerance (5% or 10%) and 1 of
32 factory-set threshold settings. Connect external
capacitors or use the factory default setting to set the
watchdog timeout periods and reset time delay.
The MAX6886 is available in a 20-pin thin QFN (5mm x
5mm x 0.8mm) package and operates over the extend-
ed -40°C to +85°C temperature range.
