It is also widely used in controlling circuits, high availability systems, and complex in-vehicle powers systems. Due to its wide operating voltage and temperature range, high reliability and low power consumption, the DS1816R-20/T&R supervisor is an ideal choice for powering any embedded application.

The DS1816R-20/T&R supervisor can also be used for other applications such as:

• Consumer electronics
• Medical electronics
• Telecommunication systems
• Industrial networks

Working Principle of DS1816R-20/T&R Supervisor

The DS1816R-20/T&R supervisor is a low-power voltage supervisor that monitors one or more supply voltages. It provides an active-low reset signal, as well as other power management signals. The device is driven by an internal oscillator that allows control of the time delay and a threshold voltage detector that specifies the reset trip point. In reset mode, the reset signal is asserted and the reset input and outputs are both in the active-low state.

Once the supply voltage passes the trip point voltage, the DS1816R-20/T&R supervisor resumes normal operation mode. In addition, the DS1816R-20/T&R supervisor has several additional features, such as power-on reset, watchdog timer, adjustable reset timeout, power-loss reset, power-fail soft reset, auto power-reset, brown-out indication, and two polarity adjustable reset thresholds.

In addition, the DS1816R-20/T&R supervisor integrates a low power wakeup circuitry that reduces the supply current to a minimum, thereby reducing system power consumption. This feature enables the device to wake up the system if any system activity is detected. This feature is especially useful when powering embedded or mobile systems.

Conclusion

The DS1816R-20/T&R supervisor is an ideal universal power supervisor for automotive and industrial applications. It offers a wide operating voltage and temperature ranges, low power consumption and high reliability. It also provides additional features like power-on reset, watchdog timer and power-fail soft reset which greatly helps system designers to optimize the system power management function. Therefore, the DS1816R-20/T&R supervisor is an ideal choice for powering any embedded application.
