PMIC (power management integrated circuit) is a device used to regulate the power supply and power distribution in a system. PMICs usually include drivers, controllers and supervisors, working together to manage the power in the system. Supervisors are tasked to detect power failure or short circuit and to generate reset signals or invoked system backup. DS1836C-10 was developed and provided by Dallas Semiconductor, a subsidiary of Maxim Integrated that is dedicated to innovative power management solutions. In this article, we will discuss DS1836C-10’s application field, working principle and its advantages.

DS1836C-10 is a low voltage supervisor commonly used in computer systems and embedded applications. By continuously monitoring power supply and reset levels, the supervisor draws very low quiescent current, therefore extending the battery life of many portable applications. Furthermore, it allows for a certain amount of flexibility for power on/off and other sequences in the system.

As a supervisor, DS1836C-10 has three distinct functions. Firstly, it supervises the system\'s power supply and reset levels. This is done by monitoring two input signals, namely, the power on reset (POR) and the reset pin (RS). When either of these two signals exceeds its threshold value, the output signal from the supervisor will be activated and the corresponding reset will be generated. Secondly, it monitors the system\'s temperature, allowing for the quick reaction to an unusually high temperature. This function is realized by a temperature-sensitive comparator built into the supervisor, which is used to evaluate the temperature status of the system. Lastly, it incorporates oversampling technology, which allows for a reliable reading of the system\'s voltage level even in cases of slowly changing conditions.

DS1836C-10 is a highly reliable and cost-effective solution for the reliable protection of various computer systems and embedded applications. It supports multiple operating modes, including active-low or active-high RESET modes, as well as open-drain or push-pull modes. Additionally, it also offers flexibility in terms of the reset timer and slew rate. DS1836C-10 ensures that the system is always under control and is able to reset and safely restart after an unexpected power failure or overheat. Furthermore, it provides an internal stability check and can also be used to guard against under-voltage conditions.

To conclude, DS1836C-10 is a versatile and reliable low voltage supervisor that provides superior protection to various computer systems and embedded applications. It monitors the system\'s power supply, reset levels, and temperature, while providing over-voltage and under-voltage protection. Furthermore, it provides flexibility in terms of the reset timer and slew rate, making it a cost-effective and reliable solution.
