Rochester Electronics MAX161ACPI Environmental and export classification status description

Overview of Maxim Integrated MAX161ACPI The MAX161ACPI is a precision supervisor and reset controller designed for monitoring critical voltages and ensuring proper system operation in a variety of electronic devices. It helps in protecting microcontrollers and other systems from undervoltage conditions by generating a reset signal when the supply voltage falls below a predefined threshold. Key Features: - Low Voltage Operation: The MAX161A can operate down to 1.5V, which makes it suitable for low-voltage applications. - Adjustable Reset Thresholds: Configurable reset thresholds allow customization according to different system requirements. - Active-Low/High Output: The reset signal can be configured for active low or high output. - Debounce Timer: An internal debounce timer ensures that short voltage fluctuations do not unnecessarily trigger a reset. - Ultra Low Supply Current: The device consumes minimal current, which is essential for battery-operated devices. Functions 1. Voltage Monitoring: Continuously monitors the supply voltage of the microcontroller or system to ensure it remains above acceptable levels. 2. Reset Generation: Issues a reset signal when the supply voltage drops below set limits, protecting the system from unintended behavior. 3. Debounce Functionality: Prevents spurious resets from voltage fluctuations, enhancing system stability. 4. Output Configuration: Allows settings for the type of reset output (active-low or active-high) based on specific requirements. Applications - Microcontroller Systems: Used in microcontrollers and processors to maintain stable operation. - Battery-Powered Devices: Essential in devices where power management is critical. - Consumer Electronics: Used in TVs, audio equipment, and other consumer goods. - Industrial Control Systems: Provides voltage monitoring and reset functions in machinery and control systems.
