The S-80846CNMC-B87T2G is a power supervision integrated circuit (IC) from NXP. It\'s made to be used as a supervisor for power management in applications with low pin count.

The S-80846CNMC-B87T2G is a 3 pin, low dropout (LDO), power supervisor with a power-on reset (POR) circuit, as well as temperature and voltage monitoring. It monitors an operating voltage range of 0.8V to 5.6V, and switches to an active low reset signal when an out of tolerance condition exists. The IC has a fast response time of 0.04µs, providing the necessary reset protection for today\'s modern integrated circuits.

This LDO supervisor is designed to provide an improved solution for smart and mixed signal applications, offering the best possible power management experience. The added benefit of its wide operating voltage range makes it suitable for supplying power to many types of integrated circuits, providing reliable reset and power supply monitoring for the entire system.

The S-80846CNMC-B87T2G is ideal for use in applications such as system-on-module platforms, cellular baseband, RF transceiver, and many other high performance computing systems. It is also suitable for use in FPGA, industrial, medical and other applications where low pin count is needed.

The S-80846CNMC-B87T2G has an adjustable under-voltage lockout (UVLO) and programmable reset pulse duration. The reset pulse duration can be programmed to provide a more robust and reliable reset signal, while the adjustable UVLO allows operators to easily customize the start-up and shut-down levels of their system. This ensures the system is stable and efficient in various conditions.

Temperature monitoring and alarm supervisory feature is provided, which allows the system to monitor and alert the user of any temperature variation. The S-80846CNMC-B87T2G also has a master reset feature that can be used to control multiple supervisors from a single control line. This feature allows the system to easily perform a manual reset or a global reset.

The working principle of the S-80846CNMC-B87T2G is based on power monitoring and reset control. The IC keeps track of the system\'s power status (voltage and temperature) and provides a signal when an extreme condition is detected. For example, when the voltage drops below the undervoltage lockout or if the temperature goes too high, the LDO supervisor will pull the signal low to alert the system of an error. The integrated circuit will remain in this error state until a reset occurs.

The S-80846CNMC-B87T2G is a versatile power supervisor IC that provides reliable protection and control in applications with low pin count. Its wide operating voltage range and programmable reset pulse duration allow operators to customize the start-up and shut-down levels of their system, while its temperature monitoring feature ensures the system stays stable and efficient while in operation. This makes it an ideal choice for various types of smart and mixed signal applications.
