The SI3993DV-T1-E3 is a high voltage power switch (HVPS) with an integrated logic gate array. This HVPS provides a high voltage supply as well as a means of switching it between multiple potential applications. The SI3993DV-T1-E3 features an integrated low voltage logic gate array, enabling users to control the flow of power in multiple directions while keeping a precise switching ratio. The power switch is designed to operate within the 0.5 to 20 V range.The SI3993DV-T1-E3 consists of two separate FET arrays, one for the low and one for the high voltage. The low voltage array is composed of an N-channel enhancement MOSFET array, based on the charge-based device. This device uses a single, or multiple, positive and negative signals to vary the threshold voltage and switch between the high and low voltages. The high voltage array is an N-channel depletion MOSFET array and is optimized for high voltage operation. This device works by preventing the accumulation of charge by building an electric field at the gate that is strong enough to block current. These two arrays are connected in series and the logic gates allow users to switch between multiple voltage levels.The SI3993DV-T1-E3 is designed to as a power switch in low power applications, such as personal electronics, automotive, and medical devices. In these applications, it can be used to switch between two or more voltage levels, such as 3.3 V and 12V. It is also used in power management applications, such as Battery Management Systems (BMS). Here, it is used to manage the voltage between two or more sources and prevents battery drain.The SI3993DV-T1-E3 is a high voltage power switch with an integrated logic gate array, offering precise control over the switching process. It is designed for a variety of applications, from personal electronics to automotive and power management. It is a reliable, efficient, and cost-effective solution for switching between multiple voltage levels.
