PMIC - Supervisors, or supervisory circuits are useful in both industrial and consumer applications. They are broadly classified into two groups: manual and automatic. The X5169PIZ belongs to the automatic group of supervisors.

The X5169PIZ is a low-power automatic supervisor IC that operates on 1.8 V to 5.5 V power supplies. It is small in size and a cost-effect solution for system supervision and reset. It includes an input monitor that can detect small changes in current or voltage levels, and an output resetter that drives an active-low reset output. The IC has been designed to provide reliable power-on-reset as well as power-sequence and brown-out protection for various systems.

The X5169PIZ IC is used in various applications that require fault protection and resets, such as low-power embedded systems, automotive systems, servers, networking equipment, and industrial controllers. It is also suitable for digital logic and RF device protection. With its active-low reset signal, the IC allows the reset duration to be matched to the minimum clock cycle of the system.

The X5169PIZ employs a time-based reset algorithm known as the power-on reset (POR) circuit. This allows the IC to produce a reset signal when the voltage of the positive supply is below the reset threshold. The reference voltage of the IC is selected automatically according to the input voltage range and the reset threshold. The reset pattern of the IC is also programmable, enabling it to produce an active-high, active-low, or single reset pulse.

To ensure system stability and reliability, the X5169PIZ also features an error latch that causes the reset signal to remain active until cleared. This feature prevents the system from resetting itself multiple times in the event of an error. The IC is also equipped with a watchdog timer, which is used to monitor system health and detect system hangs or freezes. The IC can be powered down for power savings and restarted with a minimal current consumption.

The X5169PIZ\'s small size and low power consumption make it an ideal choice for applications where space and power are limited. Its wide input voltage range and adjustable reset threshold also give it an edge over other supervisors for industrial and consumer applications. The programmable reset pattern, error latch, and watchdog timer provide improved system protection and reliability, making the X5169PIZ an excellent choice for any system requiring automatic reset.
