Ultra Low Cost 3-Pin Microprocessor Reset

Description

The V6340 monitors the supply voltage of any electronic

system, and generates the appropriate Reset signal. The

threshold must be chosen to the minimum allowed voltage

which guarantees the good functionality of the system. As

long as VDD stays upside this voltage level, the output stays

inactive. If VDD drops below VTH, the output gets active.

The threshold voltage may be obtained in different versions:

2.6V, 3.0V, 3.7V and 4.4V.

Features
