Power distribution switches are an integral part of system design in virtually every application. They are used to control the flow of current and voltage between power sources, load drivers, and logic components. The VN7140ASTR is a power distribution switch designed for >20V applications and is specifically designed for low total power dissipation. It is a cost effective solution for providing low on-resistance and low voltage drop over a wide temperature range.

The VN7140ASTR is a bi-directional, high side power distribution switch that can be used to switch DC loads in lighting, instrumentation, HVAC, and surveillance system applications. The device features a proprietary internal //-reversing circuit that eliminates the need for an external N-channel MOSFET. It features a low on-state resistance of 0.42 Ω and a maximum voltage drop of 0.5 V when switching loads up to 500 mA. Additionally, the device includes a schmitt-trigger input that enhances noise immunity and offers maximum flexibility in switching angles.

The VN7140ASTR operates over a wide temperature range from -40°C to +125°C and is protected from a variety of external conditions such as overvoltage and overcurrent. The device comes in a small BGA package and has an exposed thermal pad for improved thermal dissipation. It has a range of built-in protection features including EMI filters, dielectric strength protections, and snapback levels. Additionally, the device has a low quiescent current of 0.1 mA and a low start-up current of 0.2 mA.

The VN7140ASTR is a low-cost, robust power distribution switch that provides reliable operation in harsh environments such as those found in automotive and industrial applications. Its controllable power switching circuitry and overvoltage protection should make it the perfect choice for applications where space and power efficiency is a concern. The device\'s wide temperature range provides the versatility that is required by many modern applications, while its low quiescent and start-up currents add to the utility of this already impressive power device.
