The MAX708RESA-TG from ON Semiconductor is a highly reliable, low-power microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides a significant level of system protection by asserting a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring that the μP and associated circuitry reset cleanly during power-up, power-down, and brown-out conditions.

Key Features

• Precision Voltage Monitoring: The device is equipped with a precision voltage sensor that monitors the system voltage levels, providing timely reset signals to safeguard the system against improper operation due to low voltage conditions.
• Programmable Reset Timeout: It offers a programmable reset timeout delay, which ensures that the system has sufficient time to stabilize before the microprocessor starts to execute code.
• Low Power Consumption: Engineered for power-sensitive applications, the MAX708RESA-TG consumes minimal power, making it an ideal choice for battery-operated and portable devices.
• Wide Operating Voltage Range: This supervisory circuit operates over a wide voltage range, accommodating various system requirements and ensuring versatility across different applications.
• Manual Reset Input: A manual reset input is provided, allowing for an external trigger to initiate a system reset, which can be useful for system debugging and testing.
