PMIC (Power Management and Integrated Circuits) are critical components used on any modern platform. They are what allows a platform to remain functional and/or connected to other components and/or systems. Supervisors are a specialized type of PMICs which monitor voltage levels and power conditions and trigger alarm flags or shut down the system if unforeseen conditions occur. The DS1836DS-10/T&R from Dallas Semiconductor is one such supervisor.

The DS1836DS-10/T&R belongs to the family of Low Voltage Supervisor (LVS) integrated circuits. It has many great features such as low voltage reset, low voltage watch-dog, power-good indication, adjustable reset thresholds and adjustable reset time-out delay. It is also equipped with a temperature sensor, which can be used for additional system protection.

DS1836DS-10/T&R Application Field

The DS1836DS-10/T&R is an ideal choice for any system that needs to remain operational while in the event of a severe power event. Its wide array of features make it suitable for use in consumer, automotive, industrial and medical applications. It can be used as a primary power supervisor as well as a secondary supervisory circuit. The temperature sensor can be used to trigger a reset signal when the ambient environment exceeds a pre-set threshold. This can be used to protect the system from being damaged due to excessive temperatures. Additionally, its internal latch circuit provides a “no-power” signal to indicate the system is not operating properly, which can be utilized to provide critical system status information.

DS1836DS-10/T&R Working Principle

The DS1836DS-10/T&R is a two-terminal supervisor circuit. It consists of a sense pin, two reference pins, a reset pin and a temperature monitor pin. The sense pin is used to monitor the voltage level of the input supply. The two reference pins provide overvoltage and undervoltage threshold limits to the sense pin. When the voltage at the sense pin drops below the lower reference limit, or exceeds the higher reference limit, the supervisor will trigger the reset pin and reset the system. The reset pin can be programmed with a pin-adjustable delay time, allowing the system to remain operational before triggering a reset. The temperature monitor pin is used to monitor the temperature of the system and issue a reset if the temperature exceeds a pre-set threshold.

In summary, the DS1836DS-10/T&R is an ideal choice for any system that needs to remain operational while in the event of a severe power event. It is easy to configure and has a wide array of features that make it perfect for use in a variety of applications. It provides adjustable reset thresholds, adjustable reset time-out delay, power-good indication, temperature sensing and low voltage reset. All in all, the DS1836DS-10/T&R is an excellent choice for any system requiring power management and supervision.
