ИС обеспечения резервного питания

Компания Analog Devices предлагает ряд схем супервизоров, которые представляют собой полнофункциональное однокристальное решение для контроля напряжения питания и управления батареями в микропроцессорных системах. Они обеспечивают такие функции, как формирование сигнала сброса микропроцессора, переключение на резервную батарею, мониторинг с использованием сторожевого таймера, защита записи КМОП ОЗУ и предупреждение о сбоях в цепи питания.

Области применения:

• Мониторинг микропроцессоров
• Контроллеры
• Интеллектуальные измерительные приборы
• Автомобильные системы
• Портативные измерительные приборы
