No External Components  
Low Cost  
In applications with microprocessors (µPs) that have a  
RESET input, the MAX7705 is functionally and socket  
compatible with the TL7705, but requires no external  
components. It provides power-supply glitch immunity  
and a guaranteed power-up reset delay, while typically

consuming 1/27 the power from a +5V supply.  
The MAX7705 monitors the power supply in µP and digital  
systems. The RESET output is valid for V down to 1V.

The device offers excellent circuit reliability and low cost  
by eliminating external components and adjustments.  
A system reset is provided during power-up, power-  
down, and brownout conditions. When V is below the  
CC  
reset threshold, RESET is low and holds the µP in reset.  
RESET will go high 280ms after V rises above the  
reset threshold. The MAX7705 is available in 8-pin DIP  
and SO packages.
