The DS1233-10 EconoReset from Maxim Integrated is a reliable and compact device designed to monitor the power supply status in microprocessor systems, providing an effective solution to protect against uncertain power levels. With its precision temperature-compensated voltage reference and comparator circuit, it monitors the VCC for an out-of-tolerance condition. When an invalid VCC is detected, the RESET signal is asserted, which holds the microprocessor in the reset state for a minimum of 250ms after VCC has risen above the reset threshold level. This ensures that the processor is fully reset and ready to execute correctly when power levels stabilize.

The DS1233-10 has a preset threshold voltage of 4.37V, tailored specifically for 5V operating systems. It is a versatile component, suitable for a wide range of applications including computers, controllers, and intelligent instruments, where it enhances system reliability by preventing incorrect operations during power-up, power-down, or brown-out conditions.

Key Features:

• Automatic Reset: Ensures a proper system reset, with a minimum power-on reset pulse width of 250ms.
• Voltage Monitoring: Precision monitoring for 5V power supplies with a threshold of 4.37V.
• Low Cost: Offers an economical solution for system stability.
• Compact Size: Available in a small, 3-pin TO-92 package, saving valuable board space.
• No External Components: The DS1233-10 requires no external components, simplifying design and reducing system costs.
• Wide Operating Temperature: Functions across a broad temperature range from -40°C to +85°C.

The DS1233-10 is an essential component for systems that require consistent and reliable operation, safeguarding against data corruption and hardware damage due to volatile power supply conditions. Its plug-and-play nature makes it an easy-to-integrate solution for enhancing the robustness and longevity of electronic systems.
