MAX702 - Power-Supply Monitor

General Description

The MAX700/MAX701/MAX702 are supervisory circuits used to monitor the power supplies in microprocessor (µP) and digital systems.

The RESET/RESET outputs of the MAX700/MAX701/MAX702 are guaranteed to be in the correct state for VCC voltages down to +1V (Figure 4).

Key Features

  • of the MAX701 and MAX702, the MAX700 provides preset or adjustable-voltage detection so thresholds other than 4.65V can be selected, and adjustable hysteresis. All parts are supplied in 8-pin PDIP and narrow-SO packages in commercial and extended temperature ranges.

MAX700/MAX701/MAX702 Power-Supply Monitor with Reset General Description The MAX700/MAX701/MAX702 are supervisory circuits used to monitor the power supplies in microprocessor (µP) and digital systems. The RESET/RESET outputs of the MAX700/MAX701/MAX702 are guaranteed to be in the correct state for VCC voltages down to +1V (Figure 4). They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V-powered circuits. The MAX702 is the simplest part in the family. When VCC falls to 4.65V, RESET goes low. The MAX702 also provides a debounced manual-reset input. The MAX701 performs the same functions but has both RESET and RESET outputs. Their primary function is to provide a system reset.
