The SI1967DH-T1-E3 is a high-voltage, high-speed, and low-power Fet Array designed by Siliconix. It was designed specially for the protection of devices and systems which need to be reliably driven under heavy load current or power switching. The SI1967DH-T1-E3 is ideal for applications in the automotive, communications, computing, industrial and consumer markets. This Fet Array is also highly suitable for replacing discrete Fets.

Application Field

The SI1967DH-T1-E3 Fet Array is designed to be a high-voltage, high-speed, and low-power Fet array. Specifically, it integrates eight N-channel enhancement Furukawa (FET) and/or P-channel enhancement NIKO FETs into a single package. This allows for a much narrower printed-circuit-board (PCB) trace for each device, making it ideal for higher power-density and power-efficiency designs. Additionally, its high-voltage drive capabilities help reduce power dissipation and ensure a reliable gate source and source drain electrical connection when driving high-current Fets.

The SI1967DH-T1-E3 is commonly used for automotive electro-mechanical systems, such as airbag actuation or spark plug control. Its high-speed switching also makes it suitable for applications like high-frequency power supplies, where high-speed measurements are typically necessary. Additionally, its high-voltage drive capabilities make it suitable for driving multiple, high-current Fets. This makes it a good choice for designs which require high-current, high-voltage switching, such as motor control and high-frequency power switching.

Working Principle

The SI1967DH-T1-E3 Fet Array utilizes its integrated N-channel enhancement Furukawa (FET) and/or P-channel enhancement NIKO FETS to provide high-voltage, high-speed, and low-power operation. Through its integrated protection logic, the device ensures reliable operation, even in extreme conditions.

In order to understand how the SI1967DH-T1-E3 works, it is important to understand the basic principles of FETs. FETs are voltage controlled devices that use drain-source voltage (Vds) to control the current between the drain and the source. Essentially, FETs act like switches that can be used to control the flow of current through a circuit.

The SI1967DH-T1-E3 consists of eight integrated FETs. Each FET is used to control a single portion of the circuit. When a certain voltage is sent to the FET, it will turn on, allowing the current to flow through the circuit. Alternatively, when the voltage is no longer applied, the FET will turn off, preventing current to flow.

The SI1967DH-T1-E3 utilizes its integrated protection logic to provide reliable operation under extreme conditions. This protection logic monitors each of the Fets in order to detect any potential short circuits, overheating, or over-voltage conditions.

Overall, the SI1967DH-T1-E3 Fet Array is an ideal device for applications that require high-voltage, high-speed, and low-power switching operations. Its integrated protection logic ensures reliable operation, even under severe conditions. Additionally, its high-power density and power-efficiency design helps reduce PCB trace width for each device, making it an ideal choice for high power-density designs.
