PMIC - Supervisors: ADM6711TAKSZ-REEL7 application field and working principle

The ADM6711TAKSZ-REEL7 integrated circuit (IC) from Analog Devices is a supervisor device that brings precision monitoring and protection to applications, providing System Voltage and Over Temperature Supervisors. It falls into the category of programmable voltage supervisors, that is perfect for applications that require precise monitoring and over/under voltage protection. This IC utilizes a precision voltage reference and comparator circuit, providing a preset voltage threshold and a TTL-compatible output.

Application Field: The ADM6711TAKSZ-REEL7 can be used in a variety of applications that require precise monitoring, such as computer systems, telecommunications and industrial automation. It provides precise protection against abnormal supply, and applicable to applications with a single supply voltage that can range from 1.8 V to 5.5 V.

Working Principle: The ADM6711TAKSZ-REEL7 is based on a precision voltage reference and comparator circuit. This is combined with a voltage divider, where the voltage divider consist of series connected resistors are used to set the Precision Trip Point.

The operating principle of the ADM6711TAKSZ-REEL7 is based on a comparator circuit. It compares the monitored voltage to the precise trip point reference. If the monitored voltage is lower than the precise trip point, then the output will be in the deselect state, providing an indication that the voltage being monitored is below the set precise trip point. In the same way, if the monitored voltage is above the trip point, the supervisor will provide a signal which indicates that the voltage is above the set precise trip point.

The supervisor output is a TTL-compatible open-drain output, where the output is Low when the monitored voltage is higher than the precise trip point, and High when the monitored voltage is lower than the precise trip point. The output of the supervisor can be used to indicate whether the voltage being monitored is above or below the precise trip point, and can also be used to take action if needed, such as resetting the microprocessor or shutting down the system.

The PRECISE output of ADM6711TAKSZ-REEL7 is the result of precise trimming of the trip point components on the IC. This component is highly stable, with a precision tolerance of +-1.5% over the operating temperature range. This ensures that the supervisor will provide precise monitoring to the user.

In addition to the PRECISE output, the ADM6711TAKSZ-REEL7 also features an INT output for overtemperature detection. This output is activated when the monitored temperature reaches a preset threshold. This makes the ADM6711TAKSZ-REEL7 perfect for applications where precise temperature monitoring and protection are necessary.

The ADM6711TAKSZ-REEL7 is an inexpensive and highly reliable IC option for applications that require precise monitoring and protection. It combines a precision voltage reference circuit with an open-drain TTL-compatible output, as well as an overtemperature detection circuit. This makes it ideal for a wide range of applications where precision is important, providing the user with an excellent choice for their system supervisor requirements.
