The ADM1810-5AKSZ-RL7 IC is an integrated multifunction power management IC (PMIC) with an advanced system supervisor, power management and protection functions. It integrates a variety of active and passive functions in a single integrated circuit (IC), providing increasingly stringent system requirements in one device. The ADM1810-5AKSZ-RL7 can be used as a main supervisor, responsible for monitoring multiple power sources, voltage regulators, and so on. It also provides protection features which greatly improve system reliability and reduce component count.

Application Field

The ADM1810-5AKSZ-RL7 provides a wide range of integrated functions, making it suitable for use in a variety of applications. It can be used in embedded systems such as industrial automation and medical devices, computer peripherals, portable applications such as PDAs and notebooks, automotive applications, and telecom equipment. This makes the IC capable of providing power supply and management solutions to a wide range of systems requiring reliable performance.

Working Principle

As a multifunction power management IC (PMIC), the ADM1810-5AKSZ-RL7 can be used to monitor the power supply, voltage regulator and other components in different systems. It is capable of monitoring up to four separate power sources and provides a variety of functions to protect them. It is capable of monitoring up to four voltage levels and has a watchdog timer to help prevent system lock-ups. It also provides a power-on reset (POR) feature to clear incorrect logics levels after power-losses.

The ADM1810-5AKSZ-RL7 also provides an integrated voltage regulator and driver. The voltage regulator can be used to supply any necessary voltage levels while the drivers can be used to drive an external termination device such as an LCD or FPGA. The IC also provides a brown-out detector which can be used to detect low voltage levels. The brown-out detector ensures that the system is not powered on when the power supply dips too low.

In addition, the IC provides a unique high-side current sensing feature. This feature enables the IC to sense when currents exceed the set parameters and shut down the power supply before damage can occur. This feature is especially useful for applications with multiple power channel outputs, as the current limits can be monitored separately for each channel.

Finally, the ADM1810-5AKSZ-RL7 provides a variety of power management features such as a power-on delay, a power good indicator, and a supervisor output pin. The power-on delay allows the IC to monitor the power supply before it is enabled and the power good pin indicates when the power supply is in a good state. The supervisor output can provide various system status signals.

Conclusion

The ADM1810-5AKSZ-RL7 is a versatile power management IC capable of monitoring multiple power sources and providing protection features. It can be used to monitor four voltage levels and provide an integrated voltage regulator and driver. It also provides a brown-out detector, high-side current sensing, a power-on delay, a power good indicator and a supervisor output. The ADM1810-5AKSZ-RL7 is well-suited for a variety of applications including embedded systems, computer peripherals, portable applications, automotive applications, and telecom equipment.
