PMIC - Supervisors

PMIC - Supervisors are circuits which provide power management and are designed to protect electronics in today’s powerful, low-voltage or high-voltage, systems. A particular example of this is the ADM6713ZAKS-REEL7, which is a three-channel Low Voltage Supervisor IC.

Features

The ADM6713ZAKS-REEL7 has a number of features which make it an ideal choice for low voltage supervisor applications. One of its most important features is its wide input voltage range (from 1.7V to 5.5V). Additionally, it offers an adjustable threshold over the whole input voltage range. The threshold voltage is set between 0.9V to 1.8V by using two external resistors.

The IC also features an adjustable delay circuit that sets the delay time to either the power-up or the power-down of the IC, providing flexibility for the user to fine tune the rise time or fall time. This can be adjustable between 0.75 ms and 4 seconds. Additionally, the IC comes with an open-drain output, high accuracy, and low supply current of 1.5 µA.

Application Field and Working Principle

The ADM6713ZAKS-REEL7 can be used in a variety of low voltage systems, such as in computer motherboards, medical equipment, telecoms systems, as well as automotive and industrial applications. It is particularly well suited for applications in which the user must be given a warning if the system is operating at a low voltage.

The working principle of the ADM6713ZAKS-REEL7 is fairly simple. The IC monitors the incoming supply voltage and, if it falls below the user-defined threshold, the open drain output is driven to a low state. Meanwhile, the remaining two channels act as low and high level monitors, giving the user an additional level of protection.

Benefits

The ADM6713ZAKS-REEL7 offers several benefits that make it an ideal choice for low voltage supervisor applications.

• It is easy to use, with a simple setup process for the threshold voltage and delay time.
• It provides a wide input voltage range as well as an adjustable threshold, allowing the user to tailor it to the application’s requirements.
• It features a high accuracy of 0.2%, ensuring that the monitored voltage is accurate.
• It has a low supply current of 1.5 µA, allowing the IC to be powered with very little power.

The ADM6713ZAKS-REEL7 provides the perfect solution for low voltage supervisor applications, offering features that allow the user to tailor the IC to the application’s requirements.

Conclusion

The ADM6713ZAKS-REEL7 is an ideal choice for low voltage supervisor applications, providing features like a wide input voltage range and adjustable threshold and delay times. It also offers high accuracy, low supply current, and an open drain output that gives the user additional protection from low voltage operations.
