DS1706RESA is a high-accuracy reset/watchdog manager specifically designed for applications where long-term accuracy and tight reset control are essential. It uses Resonant Interruption Technology (RIT) to sense and adjust an external interrupting device so it always triggers in the correct window and at the correct power levels. It is designed to be implemented in a variety of embedded systems and is available in small package versions.

The DS1706RESA application field mainly includes: computer systems, communication systems, industrial control systems, Aerospace systems, embedded systems, instrumentation and medical systems, military systems, automotive systems, HTPC, DTV, Set Top Box (STB), gaming consoles, industrial automation, etc.

The DS1706RESA works by utilizing the RIT technology to provide a high-accuracy reset/watchdog service. RIT uses a combination of an interrupting device, an external reference clock and a digital signal processor to provide the reset/watchdog control. The interrupting device is used to generate the reset pulse at a specified frequency and width, which is sensed by the external reference clock and then adjusted accordingly. The digital signal processor then monitors the reference clock to ensure that the reset pulse is always aligned to the reference clock.

The DS1706RESA also integrates a set of programmable internal power supplies that allow the customer to choose the right combination of reset width and precision to meet their specific application requirements. The reset pulse width can be set to one of five time settings with selectable accuracy up to ±1%. The device also provides a 0-255 ms delay feature to allow for system initialization before the reset occurs.

In addition, the DS1706RESA features a low-power active-mode current and ESD protection, as well as an integrated temperature-compensated and phase-locked oscillator to ensure reliable operation over a wide range of temperatures. It also provides various interrupt sources, such as reset active, flash busy and system reset, so that the user can monitor the health of their system and respond accordingly.

The DS1706RESA is an ideal device for applications requiring long-term accuracy and tight reset control. It provides a high-accuracy solution and is available in a variety of package sizes. As a result, it is an ideal choice for designers looking for a reliable and accurate reset/watchdog solution.
