Nexperia dual-channel 500 mA RET enables high-power load switching in space-constrained applications

 


【Lansheng Technology News】Nexperia today announced the launch of a new 500 mA dual-channel internal resistor transistor series, all in the ultra-compact DFN2020(D)-6 package. The new family of devices is suitable for use as load switches in wearable devices and smartphones, as well as in digital circuits with higher power requirements. Examples include space-constrained computing, communications, industrial and automotive applications. It is worth noting that the DFN-encapsulated RET adopts a dual space-saving solution, which can double the space utilization.


First, significant board space is saved by cleverly integrating bipolar transistors and resistors into a single package. In addition, the leadless DFN package itself is more space efficient. This strategy of effective fusion of integration and packaging fully highlights Nexperia's unremitting efforts to meet the compact space requirements of contemporary electronic devices.


In order to reduce the number of components and simplify circuit board design, the 12 new RETs combine dual-channel BJTs and bias resistors in the same package. A second integrated resistor is also connected in parallel with the base-emitter path to create a voltage divider that sets the base voltage. This in turn enables finer trimming and better turn-off characteristics. Because these internal resistors have a higher tolerance than the external resistors, RETs are suitable for switching applications where the transistor operates in either the on or off state, and help overcome the temperature dependence of standard BJTs. Additionally, costs associated with placement and manual handling are reduced.


This family of RET devices offers dual NPN/NPN, NPN/PNP and PNP/PNP options. Unlike competing devices, Nexperia RET's tiny DFN2020(D)-6 package measures only 2 mm x 2 mm x 0.65 mm and is able to fully deliver its specified 500 mA output current. The package is designed to achieve excellent thermal performance in high-power applications, delivering up to 1 W total output power at collector-emitter voltages (VCEO, open base) of up to 50 V.


Nexperia RET devices are available in standard and automotive grade (AEC-Q101 compliant) versions. The product portfolio contains more than 400 products, including single- and dual-channel RETs and a broad portfolio of resistors. The Nexperia RET family of products is available in DFN and leaded SMD packages to meet the different needs of many applications.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
