Key Features

• Voltage Monitoring: The MAX709 monitors its own power supply voltage and asserts a reset if it goes out of the designated threshold, ensuring stability and reliable operation.
• Reset Timeout: It features an adjustable reset timeout period, which can be set by external capacitors to provide a flexible delay.
• Low Power Consumption: Designed with power efficiency in mind, the device consumes minimal power, making it ideal for battery-operated equipment.
• Manual Reset Capability: A manual reset input is provided, enabling the system to be reset on command.
• Wide Operating Voltage Range: The MAX709 operates over a broad voltage range, accommodating various system requirements.

Applications

The MAX709 is versatile and can be employed in multiple applications. It's particularly well-suited for portable devices, computers, controllers, and intelligent instruments where power conditions must be monitored for safe operation. Its ability to provide a reliable reset signal to a µP makes it an integral component in preventing system errors and data corruption during power anomalies.

Technical Specifications

The device features a reset threshold voltage precision of ±1.5%, ensuring accurate monitoring. The MAX709 is also capable of sourcing or sinking 20mA of output current, allowing it to drive a reset line directly. With its wide operating temperature range from -40°C to +85°C, it is suitable for harsh environments and diverse climatic conditions.
