MAX6886

MAX6886 19-3587; Rev 1; 1/12 Pin-Selectable, Hex Power-Supply Supervisory Circuit 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 TQFN (5mm x 5mm x 0.8mm) package and operates over the extended -40°C to +85°C temperature range.
