Супервизоры

Компания Analog Devices выпускает широкий спектр наиболее точных в отрасли супервизоров напряжения и генераторов сигнала сброса для микропроцессоров. По мере уменьшения напряжений питания процессорных ядер, точность, необходимая для их надежного мониторинга, возрастает. У нас есть компоненты, подходящие для большинства областей применения – от простых трехвыводных генераторов сигнала сброса в миниатюрных корпусах SC-70 до многофункциональных супервизоров со сторожевым таймером и поддержкой переключения на резервную батарею, а также многоканальных супервизоров напряжения и устройств управления последовательностью включения/отключения питания.
