Descriptions:

The MAX707ESA is a precision µP supervisory circuit designed to monitor power supply voltages in microprocessor-based systems. It provides reset signals during power-up, power-down, and brownout conditions to ensure proper system operation. It includes a watchdog timer, manual reset input, and a push-pull active-low reset output.

Features:

1. Power Supply Monitoring:

• Monitors VCC for undervoltage conditions.
• Generates a reset signal when VCC falls below the threshold.

2. Watchdog Timer:

• Monitors µP activity; triggers reset if the watchdog input (WDI) is not toggled within 1.6s.

3. Manual Reset Input (MR):

• Allows a push-button reset for system debugging.

4. Reset Output:

• Active-low RESET (push-pull output) ensures µP reset during power anomalies.

5. Low Power Consumption:

• 35µA typical supply current for energy efficiency.

6. Wide Operating Voltage Range:

• Supports systems from 1.2V to 5.5V.

7. Temperature Stability:

• Operates reliably across industrial temperature ranges (-40°C to +85°C).
