MAX6886ETP
Pin-Selectable, Hex Power-Supply Supervisory Circuit
General DescriptionThe MAX6886 pin-selectable, multivoltage supply
supervisor monitors six voltage-detector inputs and one
watchdog input, asserting a RESETwhen 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2:100% production tested at TA= +25°C and TA= +85°C. Specifications at TA= -40°C are guaranteed by design.
Note 3:The internal supply voltage, measured at VCC, equals the maximum of IN1–IN4.
Note 4:External capacitor is charged by IS_Twhen VS_T-DIS< VS_T< VS_T-ADJ.
Note 5:External capacitor is discharged by IS_T-DISdown to VS_T-DISafter VS_Treaches VS_T-ADJ.
