Power management integrated circuits (PMICs) are an important element in the design of equipment and systems that require power control. They regulate the power needs of various components, providing a reliable and efficient flow of energy. As part of the PMIC family, supervisors are a category of devices that are used to monitor the power supply voltages in a system. These devices can provide over-voltage, reverse voltage, and under-voltage protection. The DS1236AS-10+T&R is one such device. This article provides an overview of the functionality of the device, its potential applications and its working principles.

Overview of the DS1236AS-10+T&R

The DS1236AS-10+T&R is a voltage supervisor designed for embedded applications with a two-level voltage threshold. It provides two output flags; one for the upper-level threshold and one for the lower-level threshold. The upper and lower thresholds are selectable with a wide range from 1.9 to 7.2 volts and from 0.2 to 5.6 volts, respectively, making it a highly adaptable device. It features a high accuracy of 0.25% in both upper and lower thresholds, and an adjustable hysteresis of 0.25 to 2.25%. This ensures reliable and effective voltage regulation. The device is also specifically designed for low power applications, with a low current consumption of only 11 μA for both the upper and lower levels.

Application Fields

The DS1236AS-10+T&R is a versatile device with a wide range of potential applications. Its adjustable thresholds and hysteresis make it suitable for controlling voltage levels in a variety of systems and equipment. Some examples include data processing, microcontrollers and other embedded systems, automotive systems, instrumentation, medical equipment, and banking equipment. The device can also be used as a supervisor reset timer, providing reset pulses of adjustable length when the voltage is below the upper threshold.

Working Principle

The DS1236AS-10+T&R is a simple device so the working principle is relatively straightforward. When the voltage is below the selectable lower than 0.2V or over 7.2V threshold, the DS1236AS-10+T&R will trigger a reset. The device has two output lines, an active-high output for voltages above the upper threshold and an active-low output for voltages below the lower threshold. These pins can be configured to drive active-high or active-low reset outputs depending on the application. When the voltage is between the two thresholds, the device will remain in the idle state. This can be extended for devices designed for higher precision, such as the DS1236AS-10+T&R, where specific hysteresis levels are required.

Conclusion

This article has provided an overview of the DS1236AS-10+T&R voltage supervisor and its potential applications. This device provides a reliable and efficient way to control voltages in a variety of systems and equipment. Its selectable thresholds and hysteresis levels ensure accuracy and reliability. The device is also specifically designed for low power consumption applications, making it an ideal solution for embedded systems. The working principle is also straightforward, providing reliable reset pulses when the voltage drops below a certain threshold. Overall, this device is a versatile and reliable solution for voltage regulation.
