Формирователи импульса сброса MAX700EPA+

Схема контроля микропроцессора , 3В-15В питание, выход сброса с активным высоким/низким

The MAX700EPA+ is a power supply monitor with manual reset in 8 pin DIP package. This supervisory circuit is used to monitor power supplies in microprocessor (µP) and digital systems. The RESET/complimentary RESET output of the MAX700EPA+ has to be in the correct state for VCC voltages down to +1V. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V powered circuits. The primary function of device is to provide a system reset. Accordingly, an active reset signal is supplied for low supply voltages and for 200ms after the supply voltage reaches its operating value. It provides preset or adjustable voltage detection so thresholds other than 4.65V can be selected and adjustable hysteresis. This device is typically used in computers, controllers and intelligent instruments.
