The S-80824CNY-Z2-U is a PMIC - Supervisors device that helps prevent system malfunctions by monitoring its main power supply, as well as providing reset and power-fail signal output. This comprehensive IC also features integrated power-on reset, programmable voltage monitoring, reset signal/open drain active high output, and Pre-bias startup. It includes an 8-bit slew rate control, an adjustable reset with user-programmable options and an Enable/disable control.

The S-80824CNY-Z2-U has an adjustable reset threshold that is within the range of 2.0V – 7.0V and is programmable in 8 steps. The slew rate for reset is also adjustable in 8 steps, which should be set according to the requirements of the application. It includes a low power state, enabling power-on-reset upon power up. It also features a 300msec reset timer to provide a delay before resetting. An adjustable pre-bias start-up allows the IC to start up when it has no main power present, allowing it to go directly into reset mode.

The S-80824CNY-Z2-U has a dedicated open drain active high reset signal output. This output can be used to drive reset signals to other ICs, such as RAMs, SRAMs, and Main CPUs. The active high voltage generated by the reset signal is determined by the reset threshold. The reset signal is also timelocked with the reset timer, which allows for extra time for the reset signal to return to its low state.

The S-80824CNY-Z2-U also includes several features to protect the system from power-fail events. When the voltage falls below the programmed threshold, it will then generate a power-fail signal. This signal can be used to power down the system and/or start backup power sources. It also features an auto-restart function, which is activated when the power-fail signal has been removed. This function restarts the system without the need for a manual reset.

The S-80824CNY-Z2-U is designed for a wide range of applications, such as remote monitors, communications systems, and system power supplies, as well as automotive, industrial, and consumer applications. These applications require the monitoring of power supplies, reset signals, and power-fail events. The adjustable reset threshold and slew rate, along with the active high reset signal and pre-bias start-up, make the S-80824CNY-Z2-U an ideal solution for these types of applications.
