PMIC or power management integrated circuit is a device that helps to manage the different power requirements of electrical and electronic components. It consists of various power switches, converters, regulators, and other components that are designed to meet the power management needs of the device. The DS1813-10 is a CMOS voltage monitor supervisor with reset, watchdog timer, and adjustable reset delay. It is available in SOT23-5 and SOT23-5L packages. The DS1813-10 supervisor provides three functions: voltage monitoring, reset and shut down control, and system Watchdog timer with adjustable reset time. The voltage monitoring feature ensures that system voltage does not exceed the set over-voltage threshold. If it does then the supervisor activates the reset and shut down control circuit which will reset the system and shutdown the power. The Watchdog timer helps to reset the system in the event of a software failure or the system stops responding. The DS1813-10 supervisor is mainly used in applications where there is a need for system power monitoring such as communications, computing, network, and consumer electronics. It is suitable for powering up or resetting systems as well as providing superior system management and protection. The DS1813-10 supervisor works by sensing the system voltage and comparing it to the over-voltage threshold. If the system voltage is greater than the threshold the reset and shutdown control circuitry activates which shuts down the power and resets the system. The watchdog timer checks the system timer every set period of time and generates a timeout signal if it does not detect any activity. The DS1813-10 offers several features that make it very suitable for these applications. First of all, it offers a wide operating range of 1.7V to 5.5V, with low current consumption and low operating temperature. Additionally, it has a reset output voltage from 0.1V to 1V which makes it more versatile for different voltage levels. Finally, it has an adjustable reset time from 0.1 second to 30 seconds which allows for different levels of system protection. In summary, the DS1813-10 is an ideal supervisor for a wide range of applications that require system power monitoring and resetting. It is available in a small SOT23-5 or SOT23-5L package and offers a wide operating range, low current consumption, and adjustable reset time. It is ideal for consumer electronics, communications, computing, and network equipment.
