Power Management Integrated Circuits (PMICs) are essential components in modern electronics, as they enable efficient and reliable delivery of power to computing, communication, and consumer applications. Supervisors, a subtype of PMICs, are designed to prevent a wide range of current and voltage fluctuations from damaging sensitive components and endangering device, user, and data integrity. In this article, we will discuss the S-80841CNNB-B82T2G Supervisor PMIC, its application field and its underlying working principles.

S-80841CNNB-B82T2G is a Supervisor PMIC designed for the power management of RS-232 and similar serial communications links. It provides the necessary protection from faults in both the input supply voltage and the output voltage across the connected device, ensuring the safe and efficient operation of the system. S-80841CNNB-B82T2G has a minimum detection voltage of 5V and is specified to have an operating voltage range of 4V to 10V. It is a single-channel device with an adjustable under-voltage threshold provided via a resistor, and is programmable with a low-voltage trip point of 2.7 or 2.8V. Additionally, it provides support for a volt-second timer that allows pre-trip sensitivity to be set.

The S-80841CNNB-B82T2G is typically used in standard RS-232-level application systems. It provides a cost-effective approach to protect sensitive components from significant voltage transients, spikes, and negative swings present on serial communication links. In doing so, it helps to ensure system reliability and data integrity that is essential in communication-intensive systems. It is suited to a wide range of application areas, such as computer and data communication applications, automotive infotainment systems, industrial devices, healthcare devices, and consumer electronics.

The S-80841CNNB-B82T2G Supervisor PMIC employs advanced protection technology to ensure devices are not damaged by unexpected current or voltage fluctuations. It has a dual-zone output foldback feature which prevents system damage from over-voltage situations. Additionally, it has a visible LED indicator which alerts the user to any Under-Voltage Lockout (UVLO). The UVLO feature is designed to protect against rapidly rising voltages which can damage the connected device. The S-80841CNNB-B82T2G also utilizes a voltage clamp circuit to protect against negative voltage fluctuations, further enhancing system reliability.

The S-80841CNNB-B82T2G Supervisor PMIC\'s working principle is based on the use of three main components: a comparator, an output amplifier, and an output driver circuit. The comparator is used to compare the input voltage with an adjustable preset threshold. If the input voltage is within the specified range, the output amplifier is used to boost the signal and drive the output driver, which in turn will deliver the desired output voltage. If the input voltage is outside the specified range, the output driver circuit is disengaged and the output voltage is held low until the input voltage returns to within the set range.

In conclusion, the S-80841CNNB-B82T2G is a Supervisor PMIC designed for the power management of RS-232 and similar serial communications links. It utilizes advanced protection technology to ensure devices are not damaged by unexpected current or voltage fluctuations, and provides a visible LED indicator to alert the user to any Under-Voltage Lockout (UVLO). Its working principle is based on the use of a comparator, an output amplifier, and an output driver circuit, which work together to ensure protection and reliable operation of the system. The S-80841CNNB-B82T2G is a great choice for a wide range of application areas, such as computer and data communication applications, automotive infotainment systems, industrial devices, healthcare devices, and consumer electronics.
