Формирователи импульса сброса MAX6886ETP+

Схема контроля микропроцессора , 6 мониторов, 2.7В-5.8В питание, выход сброса с активным низким

The MAX6886ETP+ is a pin selectable, hex power supply supervisory circuit in 20 pin TQFN package. This pin selectable, multivoltage supply supervisor monitors six voltage detector inputs and one watchdog input, asserting an active-low RESET when inputs drop below the selected voltage thresholds or 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 watchdog timeout periods and reset time delay. It is used in telecom, networking and servers/workstations/storage systems.
