A PMIC supervisor is an analog integrated circuit (IC) designed to provide voltage monitoring and regulation for electronic systems. The ADM1812-5AKSZ-REEL is a low power supervisor with two voltage monitor pins and reset output. It operates at up to 1.8V and features an input current limited reset generator, active-high enable, adjustable reset timeout and push-pull reset output. This device is ideal for sample and hold applications, as it provides continuous monitoring of the regulated power supply and enables power to the system in the eventuality of a fault.

The supervisor has two separate voltage monitoring pins that allow the detection of two separate supplies or two different voltages of the same supply. The two voltage thresholds can be configured independently, allowing the device to be used for different power supply tolerances. The reset output is active high, meaning that the reset signal is logic high when the voltage drops below the reset threshold. The reset timeout feature allows the reset pulse width to be adjusted using an external capacitor. This indicates that the reset duration is dependant on the capacitor value, allowing the reset pulse to be kept tight for applications requiring quick fault recovery.

One of the main advantages of the ADM1812 supervisor is its low power consumption. The device runs at low forward current and low standby current, enabling its use for battery-powered systems. Additionally, its minimum supply voltage of 1.8V makes it suitable for battery operated devices. Furthermore, the device has comparable robustness when compared to its competitors, allowing it to withstand up to 80V operating voltage spikes.

The ADM1812-5AKSZ-REEL supervisor can be used in a range of different applications. Its wide input voltage range makes it suitable for microcontroller or embedded applications where multiple supply levels are required. Furthermore, its low power consumption makes it ideal for applications where power conservation is paramount such as portable medical devices or battery powered systems. Additionally, its low ground current makes it suitable for applications in noisy environments, as it does not need to be powered from a noisy power supply.

In conclusion, the ADM1812-5AKSZ-REEL supervisor is an ideal choice for applications requiring multiple voltage monitoring and regulation. Its low power consumption and wide voltage range make it suitable for a range of different applications such as battery powered and embedded systems. The device features adjustable reset timeout and push-pull reset output, making it suitable for sample and hold applications. Furthermore, it is robust enough to withstand operation up to 80V operating voltage spikes, making it an invaluable resource for power management.
