The ADM1818-10AKSZ-RL is an integrated supervisor integrated circuit (IC) from Texas Instruments. It is part of the PMIC - Supervisors family of components and is used for monitoring and controlling applications. This IC provides three time selectable power-up/down reset functions and an open drain reset output.

The ADM1818-10AKSZ-RL includes three reset outputs, each with different characteristics. The first is a power-up/down reset that is active when the power supply falls below the reset threshold. The second is a low voltage reset that is active when the voltage drops below the reset threshold, or when the power supply rises above the reset threshold. The third is an adjustable reset that is triggered when the voltage exceeds a selected threshold.

The ADM1818-10AKSZ-RL also provides a watchdog timer that is used to prevent system lockup. This is accomplished by continuously measuring the amount of time since the last designated watchdog timer reset. If the time exceeds a specified interval, then the watchdog timer issues a reset.

The ADM1818-10AKSZ-RL is used in several applications. It is used in power supply monitoring, where it can detect overvoltage, undervoltage, and overcurrent conditions. It is also used in system power sequencing applications, where it can synchronize the power rails and provide protected sequencing. Finally, it is used in temperature monitoring applications, where it can detect over-temperature conditions.

The working principle of the ADM1818-10AKSZ-RL is based on the monitoring of power supply, voltage, and temperature levels. The IC contains three reset outputs, each of which has different characteristics. These reset outputs are triggered when the monitored levels exceed the set thresholds. Additionally, the IC measures the time elapsed since the last reset, and if the monitored conditions remain unchanged for too long, then the watchdog timer activates and issues a reset.

The ADM1818-10AKSZ-RL is designed to provide a variety of power-up/down reset functions and an open drain reset output. It is used in several applications including power supply monitoring, system power sequencing, and temperature monitoring. It is a reliable and cost-effective solution for applications that require monitoring and controlling functions.
