PMIC (Power Management IC) Supervisors have become increasingly important in modern electronic circuitry. As such, they are integrated into a wide variety of products and applications, and one of the most popular of these supervisors is the TC54VN2802EZB. This article will explore the application fields and working principle of this important supervisor IC.

When working with integrated circuits, voltage supervisors are designed to monitor and regulate various key functions of a device, typically an entire chipset or system on a chip. These supervisors play a key role in the protection of several components, helping to ensure the safe operation of the device in multiple applications. The TC54VN2802EZB is specifically designed for power management applications and offers low power consumption, a micro-power reset source, and low noise performance.

This voltage supervisor is used primarily in power systems where it is tasked with providing accurate, consistent readings of the supply voltage. This means that the TC54VN2802EZB is able to will serve as a protection device, monitoring the supply voltage and actively shutting down the system whenever an amplitude or frequency threshold is breached. This can help to protect the system from damaging high or low voltage spikes which may be encountered during certain operations.

The supervisor is also able to detect low voltage dropouts and will then initiate appropriate shut down procedures accordingly. This is particularly beneficial in portable electronic devices, such as smartphones, where a power surge can potentially damage components. The supervisor also helps in providing voltage control, which prevents incorrect voltage levels from being applied to key components.

The TC54VN2802EZB is simple to use and is able to operate a wide range of voltages which ranges from 1.65V to 5.5V. This broad range allows for use in a variety of different applications. The supervisor is able to provide fixed reset other pulses, which activate the chipset’s reset input either at power-up or when the voltage drops below a certain threshold. This allows for power up sequencing, power down sequencing, and precise voltage monitoring.

The supervisor also provides a range of configurable options, ranging from timing characteristics such reset down-delay, reset up-delay, reset to reset delay, reset on hold delay, and so on. This allows for further customization depending on the application. Lastly, the supervisor also offers a fantastic system integration as it comes in a surface mount package which occupies minimal space on the PCB.

In summary, the TC54VN2802EZB supervisor integrates several key features for use in power management applications. The supervisor can provide accurate readings of the supply voltage and actively shut down the system if any thresholds are breached. It is also able to detect voltage dropouts and provide precise voltage control. The supervisor is highly flexible and provides configurable options which allow for further customization. It is also notable for its system integration capabilities as it can fit into a small space integrally.
