Формирователи импульса сброса MAX814KCPA+

Схема контроля , ручной, активный высокий/низкий, 1В - 5.5В, 4.8В порог, 200мс задержка, DIP-8

The MAX814KCPA+ from Maxim Integrated Products is a high accuracy microprocessor (µP) supervisory circuit in 8 pin DIP package. This supervisory circuit provides power-on reset and power-fail functions. It eliminates manual trimming and improve reliability in critical applications needing high accuracy reset thresholds. The RESET (active-low) output is to be in correct state for VCC down to 1V. The reset comparator is designed to ignore fast transients on VCC. Typical application includes controllers, intelligent instruments, critical microprocessor (µP) power monitoring and set top boxes.

• Supply voltage range is 1V to 5.5V
