The S-80825CNUA-B8KT2G is a supervisory power management integrated circuit (PMIC) specifically designed to help monitor the power system on applications such as microprocessors and other stepped-down voltage systems. The device contains a voltage regulator, monitoring circuits, reset control circuit, watchdog timer and digital delay timer. The device is suitable for use in embedded circuits, such as in server systems and communications equipment.

The voltage regulator of the S-80825CNUA-B8KT2G is designed with a maximum input supply voltage of up to 16V and a regulated output voltage of 3V to 11V. Thus, the device can effectively provide a regulated voltage source for an array of applications which require it. The device is capable of supplying current up to 1.3A in total with a dropout voltage of 0.2V.

At the heart of the device lies its monitoring capability which can detect fault conditions and initiate corrective action to protect the system in the event of a power fault. The device monitors supply voltages and signals, initiating a reset when out of range. The reset signal is then used to reset or disable the system or restart function. Additionally, the device also features selectable filter delays to accommodate longer fault transient times.

The watchdog and delay timer are used to provide a method of detecting runaway software or hardware problems. The watchdog timer monitors a continuous signal from the processor and resets the system if the signal is not received within an adjustable timeout period. This system can be used to reset the processor or other circuit, or to re-enter an unknown state. The delay timer is used to provide a delayed reset or I/O warning to the system. This function is typically used to prevent false resets when the supply voltage is changing rapidly. The device is capable of generating a warning reset when the supply voltage is too low.

The S-80825CNUA-B8KT2G is designed to provide reliable protection against system faults, ensuring the longevity of the circuit. The device features an open drain output and a low input current, allowing a wide range of operating temperatures and conditions. The reset signal has a wide voltage range, allowing the device to operate in both 5V and 3V systems, making it suitable for a wide range of applications. Additionally, the device has a low power consumption, making it ideal for use in battery-powered and energy-saving devices.

The S-80825CNUA-B8KT2G provides an effective and reliable power management solution for numerous applications. The voltage regulator ensures a reliable power supply, while the monitoring circuitry provides effective protection against system faults. The watchdog and delay timer provide advanced fault protection to ensure the integrity of the system. The low power consumption and wide operating temperature range make it suitable for a variety of applications, from servers to portable devices.
