Формирователи импульса сброса MAX709LESA+

Схема контроля микропроцессора , 1.2В-5.5В питание, выход сброса с активным низким, с открытым стоком

The MAX709LESA+ is a power supply monitor with reset in 8 pin NSOIC package. This device provides a system reset during power-up, power-down and brownout conditions. The RESET goes low when VCC falls below the reset threshold and holds the µP in reset for 140ms minimum after VCC rises above the threshold. The RESET output needs to be in correct state with VCC down to 1V. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V or +3V powered systems.

• Supply voltage range from 1.2V to 5.5V
• Operating temperature range from -40°C to 85°C
• No external components are required
• Immune to short negative VCC transients
• Low supply current of 65µA
• Reset threshold of 4.65V
