MAX709, Power-Supply Monitor with Reset

The MAX709 provides a system reset during power-up, power-down, and brownout conditions.

When VCC falls below the reset threshold, RESET goes low and holds the µP in reset for 140ms min after VCC rises above the threshold.

The RESET output is guaranteed to be in the correct state with VCC down to 1V
