PMIC (Power Management Integrated Circuits) are semiconductor devices that are used to manage power in the modern digital circuit applications. Supervisors are one of the major subclasses of suchpower management ICs. These ICs integrate controller, regulator and supervisor functions, and are designed to provide protection scheme for digital applications. An example of these power management ICs is the Dallas Semiconductor DS1836AS-5 that is an ideal solution to replace discrete components with a single chip solution.The DS1836AS-5 is a low voltage supervisor, which allows a monitoring of a system\'s power supply. It provides two independently programmable outputs in response to over-temperature, overvoltage and undervoltage conditions. The device contains a temperature reset circuit that helps identify when the temperature of the system has exceeded the maximum thermal limit. It also features an on-chip comparator with hysteresis for error-condition detection.The DS1836AS-5 has two operating outputs. The reset output is used to indicate when an error condition is present. The output is held in reset state when the power supply is at the correct voltage and temperature levels. The power-good output is used to indicate when the power supply is at the proper voltage and temperature levels.The DS1836AS-5 contains a voltage supervisor, which monitors the system\'s power supply through a single precision comparator. The device features a 0.5V positive threshold and a 0.4V negative threshold. Adjustable thresholds and reset delay value allows for customizing the device for various system requirements.The reset delays can be programmed from 0.1s to 10s using two external resistors connected to four pin options of the chip. Modifying these resistor values allow the part to be tailored to a specific application such as DC-to-DC converters, HVAC controllers, portable medical devices and battery backed systems.The DS1836AS-5 contains an internal temperature sensor that can be used to monitor the temperature of the system. It contains a reset comparator which can be triggered when the temperature of the system has exceeded the maximum thermal limit. An internal temperature reset circuit allows the system to automatically reset when the temperature has cooled down.The DS1836AS-5 is ideal for applications that require an overvoltage, undervoltage or over-temperature protection. It can be used in DC-DC converters, portable medical systems, HVAC controllers andother embedded applications. It is available in small 8-pin SOIC, 8-pin MSOP, 8-pin DIP packages, making it suitable for various applications.The DS1836AS-5 is a low power consumption devices, with a normal operational current of only 4uA. Its tiny size and low consumption makes it suitable for power management applications involving minimal space and low power consumption. It is a reliable, user-friendly and easily-reconfigurable device that offers a simple, yet effective power monitoring solution.In conclusion, the DS1836AS-5 is a low voltage supervisor designed to be used in applications such as DC-DC converters, portable medical systems, HVAC controllers, and other embedded systems. Featuring adjustable thresholds and reset delays, it provides excellent overvoltage, undervoltage and over-temperature protection. With a tiny size and low power consumption, it is an ideal solution for minimal space and low-power applications.
