The MAX705ESA+T is a microprocessor (µP) supervisory circuit manufactured by MAXIM (now part of Analog Devices). Below are its key specifications, descriptions, and features:

Specifications:

• Manufacturer: MAXIM (Analog Devices)
• Package: 8-SOIC (150mil)
• Operating Voltage Range: 1.2V to 5.5V
• Reset Threshold Options: Adjustable or fixed (4.40V, 4.65V, 4.00V, 3.08V)
• Reset Timeout Period: 140ms (min), 280ms (typ)
• Operating Temperature Range: -40°C to +85°C
• Quiescent Current: 35µA (typ)
• Manual Reset Input: Active-low (MR)
• Power-Fail Comparator: Yes (PFI/PFO)
• Watchdog Timer: 1.6s (typ)

Descriptions:

• The MAX705ESA+T monitors power supply voltages for µP and digital systems, ensuring proper operation during power-up, power-down, and brownout conditions.
• It provides a reset signal to the µP when the supply voltage drops below a preset threshold.
• Includes a watchdog timer to detect µP code execution failures.
• Features a manual reset input (MR) for user-initiated resets.
• The power-fail comparator (PFI/PFO) warns of impending power loss.

Features:

• Precision Voltage Monitoring for reliable µP reset.
• Low Power Consumption (35µA typical).
• Adjustable or Fixed Reset Thresholds for flexibility.
• Watchdog Timer for system fault detection.
• Manual Reset Input for external control.
• Power-Fail Comparator for early warning.
• Wide Operating Voltage Range (1.2V–5.5V).
• Industrial Temperature Range (-40°C to +85°C).

This device is commonly used in embedded systems, industrial controls, and automotive applications where reliable power monitoring is critical.
