The ADM809-5SAKS-REEL7 is a supervisor integrated circuit (IC) that provides the operation of power on reset and power-fail reset functions. It is a high-performance circuit with a relatively low quiescent current. It has various built-in features, such as a power-on reset, brown-out detection, and loss-of-clock protection.

As one of the most reliable circuits in the market, the ADM809-5SAKS-REEL7 is currently used in a variety of applications, such as industrial automation, medical instrumentation, automotive electronics, consumer electronics, and communication systems.

Application Field

The ADM809-5SAKS-REEL7 is primarily used for application in industrial automation systems. The on-chip reset timer and brown-out detector make it an ideal solution for automatic reboot and saving system data in the event of a power failure. Additionally, its low quiescent current and reset timeout time make it suitable for use in battery-powered systems, such as medical equipment and hand-held communication devices.

It can also be used in automotive electronics and consumer electronics. The on-chip reset timer is especially useful for vehicles, where it can prevent the engine from restarting too quickly and damaging other components due to sudden power changes. The ADM809-5SAKS-REEL7 also features a wide input voltage range, making it suitable for consumer electronics applications.

Working Principle

The ADM809-5SAKS-REEL7 consists of several blocks, including a reset generator, a reset generator reset timer, a manual reset switch, a voltage detector, and a watchdog timer.

When the power is applied, the reset generator provides an active low reset signal to the system. The reset signal is high until the reset timer reaches its reset time-out value. At this point, the reset signal will be active low and the system can start executing instructions.

The voltage detector monitors the voltage of the system, and it can detect if the power is below a certain threshold. If it detects that the power has dropped below the threshold, then it will issue a power-fail reset signal. This will reset the system and ensure that the system data is not lost.

The watchdog timer can detect a system fault and automatically reset the system if the fault has not been cleared after a certain period of time. This ensures that the system always stays in a stable state.

The manual reset switch can also be used to manually reset the system if necessary.

Conclusion

In summary, the ADM809-5SAKS-REEL7 is a high-performance supervisor IC with a wide range of features, such as a power-on reset, brown-out detection, and loss-of-clock protection. It is mainly used in industrial automation systems, automotive electronics, and consumer electronics applications. Its various blocks, such as the reset generator, reset timer, voltage detector, watchdog timer, and manual reset switch ensure that the system is always in a stable state and that any power-failures are dealt with properly.
