Power distribution switches, load drivers, and other peripherals are used in electronic systems to improve functionality and reliability. The VN755S-E is a power distribution switch designed and developed by ON Semiconductor to meet the requirements of a wide variety of applications.

VN755S-E Overview

The VN755S-E is a monolithic power distribution switch integrated with two driven outputs and one non-inverting level shifter. The device is built on a 6.2 mm2 die, which includes two power transistors, two level shifters, and a low-offset buffer.

The VN755S-E offers a wide range of features such as wide operating voltage (1.2 V – 6 V), low quiescent current consumption (5 µA typically) and low minimum input voltage (1.1 V). It also offers protection from potential electrostatic discharge and overvoltage events.

The VN755S-E is available in an 8-lead VSSOP (1.65 mm x 1.15 mm) package and is pin-compatible with several competing devices such as the Si4885-FB.

VN755S-E Application Fields

The VN755S-E is ideally suited for a wide variety of applications such as consumer electronics, automotive, industrial and medical systems. It can be used as a power distribution switch in small form factor designs and as a level shifter to drive digital output stages with different logic levels.

The device is also suitable for a variety of telecom and networking applications, as it can be used to provide signal isolation and level shifting of high-speed signals from one domain to another. It is also used in USB 2.0 applications as a signal isolator.

VN755S-E Working Principle

The VN755S-E is a monolithic power distribution switch integrated with two driven outputs, a low-offset buffer, and a non-inverting level shifter. It utilizes an internal gate charge to dynamically control the output voltage, providing excellent dynamic load current handling capability.

The device has two inputs, INV and NINV, that control the output voltage. When the INV input is applied with a logic high level, the high output voltage is enabled and the output current flows from the output to ground. Conversely, when the NINV input is applied with a logic high, the low output voltage is enabled and the output current flows from ground to the output.

The level shifter is used to level-shift digital signals from one domain to another. It operates as a logic buffer, with a three-state output, to support different logic levels. When the logic low level is applied to the input, the output is a logic low, and when the logic high level is applied, the output is a logic high.

Conclusion

The VN755S-E is a monolithic power distribution switch designed and developed by ON Semiconductor for a broad range of applications. The device is available in an 8-lead VSSOP package and is ideal for use in consumer electronics, automotive, industrial and medical systems.

The VN755S-E utilizes an internal gate charge to dynamically control the output voltage, providing excellent dynamic load current handling capability. It also features two driven outputs and a non-inverting level shifter, making it an excellent choice for signal isolation and level shifting applications.
