PMIC - Supervisors are widely used and versatile devices found in a range of applications and developments in different systems. The DS1816-5/T&R makes use of advanced technology developed by Texas Instruments (TI) to bring powerful features and reliability. This article will discuss the application field and working principle of the DS1816-5/T&R.

The DS1816-5/T&R is a single-channel Precision Supervisor with two built-in voltage references for monitoring for drop-outs across output terminals. It enables a set of precision power supply functions for use in a variety of applications. The device also incorporates a reference enable input, which is used to enable or disable the internal reference, allowing for power savings when the device is not monitoring applications.

The DS1816-5/T&R is designed to be used in intelligent battery charging systems. It can be used for core voltage monitoring, as well as for monitoring dropouts across output terminals. This device can also provide precision reference for analog-to-digital converters, and for conditioning and managing battery charge level. Moreover, it is being used in MIPI solutions and provides excellent stability for long term results with 10 non-volatile memory locations.

The DS1816-5/T&R has numerous applications in other fields as well. The device is suitable for assisting in industrial, automotive, and communication applications, enabling next-generation power control, monitoring, and management solutions. It is being used as a precision 5V Reference for µP/GFCI/PD systems, providing superior reliability, accuracy, and overall protection. Furthermore, the device is being used in cell phone base band systems, ensuring a lower noise level, higher reference accuracy, and improved power efficiency.

The DS1816-5/T&R features low power consumption, power-on reset and adjustable reset with manual reset signal. It also ensures highest accuracy of reset input, allowing for better signal and signal-to-noise ratio. The device includes a watchdog timer for timeout reset and for periodically verifying system performance, and it operates at temperatures ranging from -40°C to 125°C. The hysterisis of the device allows an improved immunity to noise, making it suitable for industrial monitoring and control applications.

The working principle of the DS1816-5/T&R is very simple. It consists of a single-channel analog output IC, which is connected to a comparator that can be used to monitor a single precision reference. The comparator compares the single reference to the output value of the IC to detect dropouts. When a dropout is detected, the comparator triggers a reset line, while the IC itself also has various reset inputs and functions to facilitate different power saving and other tasks.

To summarize, the DS1816-5/T&R is an excellent device for use in intelligent battery charging systems, as well as for supporting industrial, automotive, and communication applications. Its numerous features include low power consumption, power-on reset, adjustable reset, manual reset signal, highest accuracy of reset input, and watchdog timer. It also features a very simple working principle which consists of a single-channel analog output IC and a comparator which can be used to detect dropouts. Its excellent performance and various features make it highly preferred by engineers and developers.
