PMIC - Supervisors are a type of specialised integrated-circuit (IC) that is used to provide circuit protection against damaging overcurrents and short circuits. The S-80942CNNB-G9CT2U PMIC is a dual-channel supervisor with integrated power-on reset and watch-dog timer (WDT) functions. It provides reliable protection against overcurrents and short circuits and is designed to withstand transients. The supervisor is also designed to protect against overvoltages, undervoltages, and power disruptions.

The S-80942CNNB-G9CT2U supervising IC is ideally suited for use in industrial applications due to its wide operating temperature range and superior circuit protection capabilities. It is particularly suitable for use in automotive and avionics applications due to its robustness and ability to withstand harsh conditions such as wide temperature swings and high vibration levels. It is also widely used in applications that require precise voltage regulation and robust circuit protection, such as in computer motherboards and smart phones.

The S-80942CNNB-G9CT2U supervisor IC is a low-power device, which means that it can be operated over a wide power supply range (2.5V to 5.5V). It has a high assertion voltage of 4.6V and a low de-assertion voltage of 2.3V, making it suitable for monitoring a wide range of input voltages. The IC has an active-low PWROK (Power On Reset) output, a WDI (External Watchdog Input) input, two fault outputs, and an optional WDT (Watchdog Timer) output.

The S-80942CNNB-G9CT2U supervisor IC works by continuously monitoring the supply voltages and detecting when the input voltage drops outside of its specified voltage range. When this occurs, the IC will issue a power reset pulse, which will reset any connected circuits, allowing them to start in a safe and predictable state. The IC has a number of configurable options, such as adjustable delay times, assertion and de-assertion voltages, and timeout periods.

The S-80942CNNB-G9CT2U supervisor IC also features an optional WDT (Watchdog Timer) output, which can be used to provide circuit protection against system hangs or software errors. The WDT output can be configured to reset the system after a specific period of time has elapsed, providing a robust circuit protection mechanism against system hangs or software issues.

In summary, the S-80942CNNB-G9CT2U supervisor IC is a highly reliable and robust device, which is well suited for use in industrial and automotive applications. It provides robust circuit protection and precise voltage regulation, and its wide operating temperature range makes it suitable for applications that are subject to extreme temperature swings. It also features an optional WDT output, which can be used to provide protection against system hangs or software errors.
