PMIC - Supervisors are a type of integrated circuit designed to provide fault protection for other critical devices in an application system. The DS1811-10+ is a PMIC - Supervisors device that has a wide range of applications. This article will discuss the application field and working principle of the DS1811-10+.

Application Field of DS1811-10+

The DS1811-10+ PMIC - Supervisors can be used in a variety of applications. It is particularly suited for power sequencing applications, as it can provide a precise control of multiple voltage and current levels. It can also be used in embedded systems, providing switched mode power supply control along with various fault protection features. In addition to these features, it is also capable of providing a general purpose reset with programmable delays, making it ideal for system power up and power down control.

The DS1811-10+ is also useful in automotive applications, where power protection is critical in harsh operating environments. It can provide a variety of functions such as overvoltage and undervoltage protection, power supply sequencing, soft-start and power-up delays, and overcurrent protection.

Working Principle of DS1811-10+

The DS1811-10+ PMIC - Supervisors device is based on an input voltage threshold comparator, with an adjustable sense voltage level. The sense voltage is compared against the voltage input of the device, and if the voltage is below the set level, the device will produce a low output. This output can then be used to trigger a system reset or other action.

The DS1811-10+ also features various fault protection features, such as overcurrent, overvoltage and undervoltage protection. It can detect a voltage or current that exceeds the set level and will trigger its output. It can also detect a voltage or current that is below the set level and will again trigger its output.

The DS1811-10+ also features various timing features. It can provide both fixed and adjustable delays in response to input conditions, as well as variable Pulse Width Modulation (PWM) to provide frequency control. The device is also capable of providing multiple power up and power down sequence.

Conclusion

The DS1811-10+ is a PMIC - Supervisors device that is suitable for a wide range of applications. It can provide a variety of fault protection features as well as precise output control. Its adjustable sense voltage level and timing features make it well suited for a variety of power supply sequencing applications, as well as for embedded system control.
