The DS1818R-10+T is a compact, highly efficient microprocessor (µP) supervisory circuit designed to monitor the power supplies in µP and digital systems. Provided by Maxim Integrated, a leader in the development of integrated circuits, this device ensures reliable operation and system stability by providing excellent power supply monitoring and control.

This microprocessor reset circuit is particularly useful in situations where an automatic reset is necessary during a power failure or when the power supply falls below a predetermined threshold. It provides a precise, factory-trimmed reset threshold voltage, ensuring that the µP resets reliably and without ambiguity every time.

Key Features:

• Reset Threshold Voltage: The DS1818R-10+T has a preset reset threshold voltage of 2.55V to 4.75V, which is ideal for 3.3V-powered systems.
• Low Supply Current: With its low supply current of only 20µA (typical), it is an energy-efficient solution for battery-operated devices.
• Reset Active Time: It features a minimum reset active time of 350ms, ensuring the system has adequate time to stabilize after a power disturbance before resuming operation.
• Form Factor: The device comes in a compact SOT-23-3 package, making it suitable for space-constrained applications.
• Temperature Range: It operates over a wide temperature range of -40°C to +85°C, making it reliable across various environmental conditions.
• Push-Pull Output: The reset output is of the push-pull type, which eliminates the need for an external pull-up resistor and simplifies circuit design.

Applications:

The DS1818R-10+T is versatile and can be used in a wide array of applications, including but not limited to:

• Computers and servers
• Embedded systems
• Portable/battery-powered equipment
