PMIC - Supervisors, or Primary Power Management Integrated Circuits, play an essential role in ensuring efficient and safe operation of electronic products. As an advanced power supervisor and monitoring device, the DS1831S+ is a popular choice among device makers and users. Below, we\'ll take a closer look at the application field of the DS1831S+ and its working principle.
The DS1831S+ is primarily used on motherboards which have to monitor multiple sources of power current. This system can manage and protect the board from over-voltage and over-temperature conditions, as well as from under-voltage conditions. The device\'s output is compatible with industry-standard drivers, such as addressable reset controllers, making it a versatile and desirable component. It is also suitable for various lithium-ion battery packs, as the DS1831S+ is designed to work with two cells in series.
The DS1831S+ also provides system control and facilitates the design of circuit boards around it. This is done thanks to its ability to detect multiple power events and then initiate a response appropriate to the particular situation. Common applications of the DS1831S+ are in onboard single-chip microcontrollers and mobile applications, as its low power consumption makes it ideal for those systems.
The DS1831S+ is designed to work with two voltage input sources. These two inputs can be either regulated or unregulated sources. The device has five active digital output pins for controlling an array of power control functions, such as soft start, fault reporting and power-good status.
The device also features an analog-to-digital converter (ADC), as well as an internal temperature sensor. The ADC is used to track the voltage and temperature of the external power source and provide the reset controller with meaningful data.
The DS1831S+ is capable of monitoring up to 4 unique events - over-voltage, under-voltage, over-current and over-temperature. For each of these events, an internal reset controller can be activated to automatically shut down the system and prevent damage to the device.
When the DS1831S+ detects a power event, it sends a signal to the reset controller which then terminates power to the device. This prevents further damage to the system, which could potentially lead to costly repairs or replacements. The signal is sent by a signal line which runs directly to the reset controller and is accessible via the I/O interface.
The DS1831S+ is also capable of monitoring the current, temperature and charge of the battery, which helps to extend the life of the battery and reduce service costs. The information from the sensors is accessible via an I2C interface, which can be connected to local monitoring systems for further use.
The DS1831S+ is packaged as a tiny and ultra-compact component, making it ideal for placement in compact electronics, such as mobile phones and tablets. Its low-power consumption and low pin count make it an attractive option for device manufacturers.
In conclusion, the DS1831S+ is a versatile and reliable power supervisor and monitoring device with a range of uses in a variety of electronic products. Its ability to detect multiple power events, provide meaningful data and shut down the system in the case of an emergency makes it a desirable choice for users. The device\'s ultra-compact size, low power consumption and high degree of accuracy ensure it will remain a popular option for entrepreneurs and device manufacturers in the future.
