Power management integrated circuits (PMICs) are a crucial component of any project involving power management. PMICs are responsible for regulating the voltage and current from any power sources and distributing it to the components of the system. In addition to providing power management, PMICs also provide system functions such as reset, voltage monitoring, over temperature warning and so on. PMICs are classified according to their functions such as regulators, timers and supervisors. The S-80958CNMC-G9UT2G IC belongs to the family of supervisors.

A supervisor is a device used to monitor the voltage applied to a system, and take appropriate actions should the system fail or crash. It is designed to provide early warning of an impending system failure, or reset the system in the event of a crash. A supervisor usually consists of a voltage monitor, which is responsible for monitoring the voltage, a reset generator, and a control circuit. The reset generator is then responsible for generating a reset signal when the monitored voltage exceeds the normal operating limit. The control circuit is responsible for providing various modes of reset operation and for debouncing the reset signal.

The S-80958CNMC-G9UT2G is a supervisor IC that is mainly used in mobile and portable electronics applications. It is an integrated low-power solution for voltage monitoring, over-voltage/under-voltage/brown-out detection and reset generation. The device has a wide operating voltage range from 2.2 V to 5.5 V, and can be configured to provide two independent power domain reset asserts and detect low-voltage conditions, based on the user’s design requirements. The S-80958CNMC-G9UT2G also features a built-in precision regulator that can be used to supply stable voltage and current to the IC. It also features over-current and over-temperature protection which makes it suitable for a wide range of applications.

The working principle of the S-80958CNMC-G9UT2G is quite simple. It monitors the supply voltage of the system and if the voltage level drops below a preset threshold, it will issue a reset signal to reset the system. The S-80958CNMC-G9UT2G IC has two selectable reset asserts, RST_OUT and POR#, which can be used to assert a reset signal even if the voltage falls below the threshold. The S-80958CNMC-G9UT2G offers configurable reset delay to provide more flexibility for various applications. The reset delay can be adjusted from 6 to 72 µsec, depending on the user’s design requirements.

The S-80958CNMC-G9UT2G is designed to provide superior performance in terms of power savings and system reliability. It is highly reliable due to its built-in protection features such as over-current protection and over-temperature protection. The IC supports both manual and automatic reset assertion, which allows it to be used as a versatile system supervisor. The device can also be used as a voltage monitor in systems that require over-voltage and/or under-voltage protection.

Overall, S-80958CNMC-G9UT2G is an efficient and cost-effective solution for voltage monitoring and resetting system. It is suitable for use in a variety of mobile and portable electronics application, providing superior performance, low power consumption and dependable system reliability. It is an essential component for any power management application, and it is a must-have for any project involving power management.
