S80EK-L-2-9/TR is a type of supervisory module (SMM) for power management. It is widely used in embedded systems for controlling the system power supply, monitoring the system voltages, and providing over-voltage protection for circuits. It has been designed specifically for power management applications such as microcontrollers, digital signal processors (DSP) and pulse width modulation (PWM) regulators. The device is also suitable for other power management ICs such as an integrated power cell, charge-pump, battery charger and digital power regulator.

The S80EK-L-2-9/TR consists of an internal analog to digital converter (ADC) and two resistors to form a voltage divider. The voltage divider allows the operating voltage to be monitored, and when it reaches the pre-set threshold, the SMM will activate the reset signal, shutting down the system. This reset signal can also be used to indicate when the voltage is too high, so the system can be safely shut down and restarted.

The S80EK-L-2-9/TR is a long time-tested device, providing stable and reliable performance over wide temperature and voltage ranges. In addition, it is designed to minimize board space and power consumption, making it an efficient solution for power management applications. Moreover, it comes in an extremely small package, making it ideal for small form factor designs such as handheld terminals and PDAs.

The S80EK-L-2-9/TR device works on the principle of a voltage sensing circuit. It continuously monitors the voltage levels, and when the input voltage exceeds a predetermined threshold, the SMM will activate the reset signal. This reset signal will shut down the system and reset it to a normal operating range. In addition to this reset feature, the device is also capable of generating an early warning signal and providing an over-voltage protection for circuits.

The S80EK-L-2-9/TR is an ideal solution for embedded systems, as it can easily integrate with microcontrollers, DSPs, and PWM regulators. It is also suitable for industry-standard power management ICs such as power-cell, charge-pump, and digital power regulators. Its low power consumption and small form factor features make it a perfect choice for power management in portable and embedded designs.

The S80EK-L-2-9/TR is a reliable and cost-effective supervisory module for power management applications. It is designed to maintain the voltage level accurately, and provide a reset signal when the voltage level exceeds the pre-set threshold. This reset signal can also be used to indicate when the voltage is too high, so that the system can be safely shut down and restarted. Moreover, the S80EK-L-2-9/TR is ideal for industry-standard power management ICs and comes in an extremely small package, making it the perfect solution for embedded designs.
