PMIC - Supervisors is a type of integrated circuit (IC) that provides a system with reset and power sequencing capabilities. It is used in embedded systems with special processor and memory needs. The DS1811-10/T&R is a popular supervisor IC that has been designed especially to provide reliable on-chip system reset and power sequencing features in a single package. This article will discuss the application field and working principle of the DS1811-10/T&R.

What is a PMIC - Supervisors?

A PMIC - Supervisors is an integrated circuit that provides a system with reset and power sequencing capabilities. It is an important channel for the processor to get information from the software, and it can interrupt the processor. It also tells the processor when to switch from one frequency to another. It also monitors the power status of the servo, and can prevent the system from being damaged from a voltage error. Some popular applications for the DS1811-10/T&R include industrial systems, automotive systems, telecommunications systems and network systems.

Application Field of DS1811-10/T&R

The DS1811-10/T&R is an ideal choice when needing reliable reset and power sequencing features in a single package. It is small enough to reduce the size of the PC board efficiently while providing protection against system malfunctions. Its application field includes electrical control, industrial machinery, networking, telecommunications, and any type of embedded system where reset and power sequencing is required.

The DS1811-10/T&R also has a wide operating temperature range and low power-down current to ensure stability in various temperature zones. It also supports a variety of processor families and memory types for maximum compatibility in finding the exact performance and protection needed.

Working Principle of DS1811-10/T&R

The DS1811-10/T&R uses a fixed-reset signal to signal overall system reset for reliable controlled start-up. This signal is balanced at the system input, and then analyzed to trigger the reset signal. The signal goes high to cause a reset within the voltage range of 4.5V to 38V.

The reset signal release time can be programmed to the specific needs of the device, with options ranging from 0 to 50 ms delay. The reset signal can also be active-low or active-high, depending on the circuit topology.

The system power-down sequence is controlled to ensure that the board’s power rails are safely isolated during off and soft-off states. The DS1811-10/T&R monitors voltage levels, and then sends a signal to the processor and memory if the power rail is out of range. It also prevents any power-up sequence from occurring until all power rails meet the proper reset level.

Conclusion

The DS1811-10/T&R is an ideal choice for systems that require reliable reset and power sequencing features in a single package. It has a wide operating temperature range and low power-down current to ensure stability in various temperature zones. The system reset and power-down sequence is controlled to ensure that the board’s power rails are safely isolated during off and soft-off states. With its compatibility with various processor families and memory types, the DS1811-10/T&R can provide a reliable and efficient reset principle for embedded systems.
