DS1706RESA+ is a supervisor IC developed by Dallas Semiconductor Corporation. It is a combination of three individual power supervision circuits - a microprocessor supervisor circuit, a low-battery detector circuit and a power failure detector. The device provides a sophisticated reset solution that ensures the proper system power up and power down. With the help of its advance features and functions, the device is capable of switching off loads safely during a power-down situation, protecting the system and its components from any electrical damage. The device also helps in preventing system reset caused by out-of-tolerance operating frequency and power supply voltage.

The DS1706RESA+ is mainly used in battery-powered systems such as servers and routers, as well as consumer electronic applications such as PDAs, Smartphones, portable media players and other handheld devices. The operating temperature range of the device is between -40°C and +85°C, It can be used in both 3.3V and 5.0V applications.

The DS1706RESA+ performs its functions through multiple devices, such as a reset timer, a watchdog timer, an oscillator and a voltage threshold detector. The reset timer and watchdog timer ensures that each of the device’s operation is triggered in the correct sequence, and the frequency of the operation is accurately timed. The oscillator is responsible for setting the oscillating frequency of the device. With the help of its built-in voltage threshold detector, the DS1706RESA+ is able to detect low-battery conditions, power failures and other over-voltage or under-voltage conditions. It can generate a reset or interrupt signal based on the results of the voltage detection.

The DS1706RESA+ also features several configurable settings and capabilities. It offers a selectable reset window time, which allows the user to choose the optimum reset signal timing based on the application’s power-up and power-down cycle. The device also features an adjustable reset time-out period, which allows the user to choose the time-out period according to the requirements of the application. The DS1706RESA+ also offers an adjustable reset debounce time, and a programmable brown-in and brown-out voltage range for better accuracy in voltage detection.

Overall, the DS1706RESA+ offers a simple and cost-effective solution to power and reset management. The device’s sophisticated capabilities and flexibility make it suitable for a wide range of PMIC-supervisor applications. With its high integration level and extensive feature set, the DS1706RESA+ provides reliable and safe power and reset management for critical applications.
