The S-80950CLMC-G7LT2U is a supervisor in the form of a PMIC, or Power Management Integrated Circuit, meaning that it is specifically designed for power management within a system. This device provides two or three general reset signals output on reset pins, helping to better manage power from any source and maintain stability of the system in the event of any failures or abnormalities.

This device operates efficiently due to its low power consumption, which is about 35 µA in normal operation and 5.5 µA in standby mode. This is beneficial because the device not only works effectively but also helps to conserve power. Compatible with various supply voltage sources, such as 1.2 V to 3.6 V, the S-80950CLMC-G7LT2U provides voltage monitoring and reset signaling for any component of the system.

Moreover, this particular device offers a power-on reset circuit with a reset status flag, eliminating the need for any external logic gate programming. Additionally, it also provides a reset signal that is triggered by power-on transient conditions (POR). With this signal, any component of a system can be reset in case of a power surge or any other power-on transient condition.

In terms of applications, the S-80950CLMC-G7LT2U is most suitable for use in computer systems, where it can be used as a general reset signal and for shielding other components from surges and sudden power-on transients. It is also suitable for use in embedded systems, since it is low power and does not require a lot of space. Additionally, it can be used for system monitoring, helping to monitor and protect any component of a system from malfunctions.

The working principle of the S-80950CLMC-G7LT2U is relatively simple. It operates by continuously monitoring the supply voltage VDD, while generating three reset signals (Port POR_reset, POK_reset, and HYS). The reset flag RST_status is also monitored. Whenever the supply voltage VDD drops below its preset threshold, the reset signal POK_reset is generated immediately. Additionally, the reset signal HYS is triggered when the supply voltage VDD rises above its preset threshold, which helps to prevent false resets due to minor voltage drops.

Furthermore, the reset signal POR_reset is triggered when the supply voltage VDD crosses its preset power-on reset (POR) voltage. This signal helps to protect the system from power-on transients, and is commonly used to reset a system when it is powered up. Additionally, the reset signal POR_reset can also be used for system resetting when VDD falls below the POK_reset signal’s threshold. The reset flag RST_status, which indicates the system’s reset status, is generated whenever the device is reset.

Overall, the S-80950CLMC-G7LT2U is an essential device for power management and system protection. With a low power consumption rating, it is able to generate three general reset signals output on reset pins, as well providing a power-on reset signal and a reset flag. Compatible with multiple supply voltage sources and suitable for a variety of applications, this device has proved to be an invaluable part of computer systems and embedded systems.
