ADM1816-5AKS-REEL

PMIC - Supervisors

The ADM1816-5AKS-REEL is a supervisor IC used in power management applications. It is a third generation generation near-zero power under voltage lock-out (UVLO) supervisor device designed to provide system reset capabilities, brown-out reset control, low-voltage monitoring and supervisory reset control in various power applications. The ADM1816-5AKS-REEL employs an integrated low-power comparator, watchdog timer, voltage comparator and voltage reference, enabling design engineers to easily program functional block behaviors.

The ADM1816-5AKS-REEL incorporates near-zero power UVLO capability, enabling advanced power system protection for a variety of applications. Additionally, the device includes a true broadcast disable/enable feature, where all enabled power pins can be disabled in one instruction. This feature allows for flexibility in power sequencing of multiple power domains, as well as power saving in systems with multiple power start-up points.

Application Field:

The ADM1816-5AKS-REEL is suitable for a variety of power management applications. It is typically used in industrial and consumer applications as a power monitoring and reset control IC, as well as in embedded systems where system reset control and low-voltage monitoring is critical.

• Industrial and commercial equipment such as professional audio/video (AV) and medical devices
• Device drivers and connectors
• Automotive and consumer electronics
• Embedded systems

Working Principle:

The ADM1816-5AKS-REEL monitors the power supply voltage, and when the voltage falls below a specific threshold, the ADM1816-5AKS-REEL will generate a reset signal to the processor, resetting the system. This feature ensures that the system does not continue operating when the power drops below a certain limit, as this can lead to errors and instability in the system.

When the voltage falls below the reset threshold, the ADM1816-5AKS-REEL will also generate a signal (shutdown) to turn off the power rails to all the devices in the system. This helps to prevent any potential damage to the system if the voltage remains low for too long. The ADM1816-5AKS-REEL also includes an integrated watchdog timer, which can be used to monitor the system for timeouts and generate a reset signal in the event of a system hanging.

The ADM1816-5AKS-REEL also includes an integrated voltage reference, which can be used to monitor and regulate the power rails in the system. The voltage reference provides an accurate and reliable means to monitor the power rails and ensure proper power sequencing and stability.

Conclusion:

The ADM1816-5AKS-REEL is a powerful supervisor IC which can be used to provide system reset, brown-out reset control, and low-voltage monitoring functions in various power applications. It incorporates near-zero power UVLO capability and features a true broadcast disable/enable feature, so that all enabled power pins can be disabled in one instruction, as well as an integrated watchdog timer to monitor for timeouts.

The ADM1816-5AKS-REEL is suitable for a variety of industrial and consumer applications, including device drivers, connectors, automotive and consumer electronics, and embedded systems. The integrated voltage reference can be used to monitor and regulate the power rails in the system, providing an accurate and reliable means to ensure proper power sequencing and stability.
