VSC3108XVP-01 Integrated Circuits (ICs)

Introduction

The VSC3108XVP-01 is a digital analog switch (DAS) designed specifically for general-purpose applications. It combines a 2-channel maximum power of 10 Ohms, programmable power (Hi/Low mode) information, operating voltage ranging from 2.5 to 5 VDC, and eight programmable power ranges. Its combination of high power and advanced design features makes it ideal for use in applications where high power and superior performance are required.

Application Field

The VSC3108XVP-01 is a versatile DAS ideal for a variety of general-purpose applications, including automotive, medical and industrial, and communications applications. This DAS can be used in either the Hi or Low power mode, depending on the application. In the Hi mode, the VSC3108XFP-01 can supply up 9A each of current from a single switch, making it ideal for power demanding applications such as automotive and industrial. In Low mode, the VSC3108XVP-01 can supply up to 0.2A each of current, making it ideal for applications requiring low power but higher functionality such as medical and communication device designs.

Working Principle

The VSC3108XVP-01 operates using an 8-bit digital interface. This interface is used to control the analog switches, which can be in either the Hi or Low power mode. The digital interface consists of 8-bits of addressable memory, a control register and status register. The command sequence consists of a Write-Read-Write cycle. A write cycle is used to set the desired power mode and enable the switch, while a read cycle is used to determine the current power mode, available power range and switch status. The 8-bit control registers are used to control the internal circuitry and function as the interface control register.

The Analog switches respond to a single-bit write cycle command. When write cycle is executed and the switch is enabled, the switch will be in its Hi power mode. When the switch is disabled, the switch will be in its Low power mode. As for power range, the switch can be programmed to support a maximum of 10 Ohm output power range. This power range is divided into two separate areas, Hi-power and Low-power. When a write cycle is executed, the switch automatically switches to the selected power range.

Conclusion

The VSC3108XVP-01 is a general-purpose digital analog switch designed with maximum power, programmable power and eight programmable power ranges. It is ideal for automotive, medical and industrial, and communications applications, as it can supply up to 9A each of current in its Hi mode, and up to 0.2A each of current in Low mode. The VSC3108XVP-01 operates with an 8-bit digital interface which uses a Write-Read-Write cycle to control the analog switches, and can be programmed to a power range up to 10 Ohms from a single switch.
