Maxim Integrated DS1813R-100 EconoReset with Pushbutton

The DS1813R-100 from Maxim Integrated is a highly efficient and reliable EconoReset device designed to monitor system voltage and maintain the integrity of the system during power failures. This compact component is an essential addition to any microprocessor (µP) system, safeguarding against data loss and hardware damage during unexpected power down events.

The DS1813R-100 features a precision temperature-compensated reference and comparator circuit that monitors the status of the power supply (Vcc). When an out-of-tolerance condition is detected, the reset signal is asserted, which holds the microprocessor in a reset state for a minimum of 250ms after Vcc has risen above the reset threshold level. This ensures that the µP and its peripherals are reset properly and are ready to execute correctly when power returns to a safe level.

One of the key features of the DS1813R-100 is its built-in active-low, debounced pushbutton reset input. This allows for a manual reset of the system, providing users with an additional layer of control. When the pushbutton is engaged, the reset signal is asserted, allowing for a system restart or shutdown as needed.

The device comes in a compact SOT-23 package, making it suitable for space-constrained applications. The DS1813R-100 operates over a wide range of supply voltages, from 2.5V to 5.5V, and features a low supply current, making it ideal for portable and low-power systems. Its open-drain output can interface with systems of different logic levels, providing versatility across various microprocessor platforms.

With its simple integration and minimal external components, the DS1813R-100 is a cost-effective solution for enhancing system reliability. It is commonly used in applications such as computers, controllers, intelligent instruments, and portable/battery-powered products.

Maxim Integrated's commitment to quality ensures that the DS1813R-100 meets the stringent requirements of modern electronic systems, providing a robust and dependable solution for system voltage monitoring and reset functions.
