DS1706TEUA+

DS1706TEUA+ is a precision, low-power supervisor device with four output voltage thresholds, supervised outputs, and integrated EEPROM. It is a cost-effective and easy alternative to discrete solutions. It offers superior accuracy, and its low quiescent current and negligible power consumption makes it ideal for battery-backed systems. DS1706TEUA+ is an ideal solution for supervisory or control functions in medical, industrial, or consumer applications.

DS1706TEUA+ monitors the system power rails and controls the power supply sequencing and reset. The device contains four voltage threshold comparators that monitor two or three power rails with ±1.25% threshold accuracy. The typical operating current for the device and its outputs is less than 1µA, and the operating temperature range is from -40°C to +85°C. The device also features an EEPROM that stores configuration settings and other parameters like supervisor window time-out and reset delay.

The device interfaces with an external microcontroller and communicates with it through an I2C/SMBus compatible protocol. This interface allows real-time control and monitoring of the application. The device has three independent monitored inputs, each with a programmable trip point. In addition, each input has an adjustable reference voltage that can be used to fine-tune the thresholds in order to compensate for application-specific process variations. The device can assert system power-on reset, watch-dog timer, and manual reset-on command.

The device has four voltage threshold comparators and a supervisor-window timer. The four configurable comparators trip when their inputs exceed predetermined thresholds. The window timer trips after a specified delay or when all inputs exceed trip points. When the supervisor window times out, it drives a system reset or generates an interrupt. The device has a manual reset-on command that permits system restarts from the software or from an external source.

The EEPROM stores configuration data and calibration values, as well as diagnostic information about the monitored power rails. The EEPROM is updated through the two-wire SMBus or I2C compatible interface. The EEPROM can be programmed with custom parameters to suit specific applications.

The DS1706TEUA+ is a versatile and easy-to-use supervisor device that offers superior accuracy and low power consumption. It is ideal for use in applications such as medical, industrial, or consumer systems. It provides system power-on reset, watchdog timer, and manual reset-on command. The four thresholds can be adjusted to suit specific application needs, and the adjustable reference voltages compensate for application-specific process variations. The device also includes an EEPROM that stores configuration settings and other parameters.
