Capacitor Networks, Arrays

The W3A45A391KAT2A is a capacitor network built with miniature chip technology, packaged in a 3-terminal array. It is used primarily in power conditioning, voltage reference, and integrated power sequencing applications.

Components:

The W3A45A391KAT2A contains several different components, including ceramic capacitors, blocking diodes, and N-Channel MOSFETs. The ceramic capacitors provide electrical energy storage capability, while the blocking diodes help protect the circuit from high voltage transients. The N-Channel MOSFETs are used to control the amount of current flowing into and out of the capacitor network.

Structure:

The W3A45A391KAT2A is designed to be compact and efficient. It is constructed of a multi-layer substrate material, which allows it to fit into even the most space-restricted applications. The circuitry consists of two separate power buses, which are connected via the two N-Channel MOSFETs. The power buses are then connected to the ceramic capacitors.

Applications and Functions:

The W3A45A391KAT2A is primarily used in power conditioning, voltage reference, and integrated power sequencing applications. It is used to stabilize the voltage of a system, by storing electrical energy when the supply voltage is low and discharging it when the supply voltage is high. This helps to prevent electrical interference and allow the system to run more efficiently.

The W3A45A391KAT2A can also be used to provide a constant, low-noise, and localized power supply. This is especially important when dealing with digital circuits, as any fluctuations in supply voltage can cause erroneous or unpredictable operation.

Working Principle:

The W3A45A391KAT2A works by storing electrical energy in the ceramic capacitors during periods of low supply voltage. When the supply voltage increases, the excess electrical energy is discharged from the capacitors, which helps to stabilize the voltage of the system. The two N-Channel MOSFETs help to control the charging and discharging of the capacitors, ensuring that the energy storage and release is efficient and safe.

Conclusion:

The W3A45A391KAT2A is a capacitor network, packaged in a 3-terminal array, which is used primarily in power conditioning, voltage reference, and integrated power sequencing applications. It works by storing electrical energy in the ceramic capacitors, and then releasing it when the supply voltage is high. The two N-Channel MOSFETs help to control the charging and discharging of the capacitors, ensuring that the energy storage and release is efficient and safe.
