Формирователи импульса сброса MAX6320PUK29CY+T

Схема контроля микропроцессора , 1В-5.5В питание, выход сброса с активным низким, с открытым стоком

The MAX6320PUK29CY+T is a µP supervisory circuit with watchdog and manual reset in 5 pin SOT-23 package. This microprocessor (µP) supervisory circuit monitors power supplies and microprocessor activity in digital systems. It reset input starts or restarts the µP in a known state. The reset output of µP supervisory circuit interfaces with reset input of the µP, preventing code-execution errors during power-up, power-down and brownout conditions. It is used in embedded control systems and intelligent instruments.
