The DIODES DGD2190M and DIODES DGD21904M are High-Side/Low-Side gate drivers that are used to optimally drive the gate of MOSFETs or IGBTs. The DGD2190M is an SO-8 package and the DGD21904M is an SO-14 package with a separate logic ground pin VSS; this can be used when required to separate power ground and logic ground.

This document discusses the case for using piezoelectric buzzers and piezoelectric buzzer drivers.

Note: Piezoelectric buzzers can also be referred to as piezoelectric horns or sounders, in this document they will be referred to as buzzers.

The LM63615-Q1 is a synchronous buck converter with a wide input voltage range from 3.5 V to 36 V and maximum output current of 1.5 A.

The LM63615-Q1 can be configured as an inverting buck-boost (IBB) converter with a negative output voltage.

This application note demonstrates how the LM63615-Q1 can be used as an inverting buck-boost converter, along with optional design considerations for inverting buck-boost converters such as a PGOOD or EN level-shifter.

If higher output current is required, the LM63615-Q1 is pin-to-pin compatible with the 2.5-A rated LM63625-Q1 and the 3.25-A rated LM63635-Q1.

The LM63615-Q1 is also pin-to-pin compatible with 1-A rated LM63610-Q1.

The DGD2184M and DGD21844M are half-bridge gate drivers that are used to optimally drive the gate of MOSFETs or IGBTs. T h e DGD2184M package is an SO-8 and the DGD21844M package is an SO-14 with a separate logic ground pin Vss. This can be used when required to separate power ground and logic ground.

In this discussion, the important parameters needed to design in the DGD2184M and DGD21844M are discussed.

Modular jacks (MJ) connectors and cables are broadly used to bring Ethernet signal up to 10 Gb/s depending on the category of the product. It is also possible to deliver power through it with PoE. Type 1 and 2 PoE specifications are applicable to Würth Elektronik modular jacks. In this Application Note we will study if recommendations can be extended up to Type 4. Moreover most WE MJ connectors are rated up to 1.5 A. That is why they will be tested at this current.
However, like all of the other types of input/output connectors, MJ connectors should not be plugged and unplugged (hot swapped) under load. Disconnectors products (breakers, switch, etc.) have special disconnection areas to be able to break the electric arc without damaging the contacts. This Application Note will show the capabilities of modular jacks in case they are accidently used as a disconnector product in a PoE application

This application note describes the Sigma-Delta Analog-to-Digital Converter (SDADC) in ATSAMC21N device is configured in differential mode and the SDADC results are displayed on a console. It also provides example code for both interrupt and polling methods, developed using MPLAB® X IDE and MPLAB Harmony v3 Configurator

The AL6562A is an active power factor control IC which is designed mainly for use as a pre-converter in electronic ballasts, AC-DC adapters and off-line SMPS applications.

The DGD2104M, half-bridge gate driver is used to optimally drive the gate of MOSFETs or IGBTs.

This application note provides some basic guidelines when selecting the proper crystal oscillator (XO) to work with the Renesas family of Network Synchronization PLLs (ClockMatrix, WAN-PLL). A list of recommended oscillator vendors and part numbers are provided, and have been categorized based on applicable industry standards.

This application note describes how to use the SLG47513 to implement an electric toothbrush.

The global population increasingly prioritizes oral health and hygiene. This factor is driving the utilization of toothbrushes across the world. Electric toothbrushes enhance the brushing experience and brushing habits. The most popular and effective type of electric toothbrush is one with a rotating or side-to-side movement. Motions at sonic speeds or lower are made with the help of a motor. Modern electric toothbrushes typically rely on rechargeable batteries, which are charged through inductive charging when the toothbrush is placed in a charging base between uses. They often use nickel-metal hydride (NiMH) batteries, whose nominal voltage is 1.2 V. The SLG46513 has a working voltage range from 1 V to 1.65 V, enabling control over the toothbrush’s operation.

This application note explains how to develop an elderly care alert system using GreenPAK SLG46533V.

This application note describes how to use the SLG46811 to implement an exhaust fan with an off-delay timer and a sensor for humidity control.

This application note describes how to design and build a reliable power switch with offline memory for privacy applications.

It remembers its state even during power off for an indefinite time.

This device also has an LED indicator with a fault monitoring system. Meaning, that if the LED malfunctions the switch will go off.

It has been observed that the natural color of halogen-free polyamide (PA) plastic used in Würth Elektronik connectors turns brown during the SMT process (Reflow soldering). The aim of this technical note is to understand this phenomenon and demonstrate whether and how it may impact the plastic material properties of our connectors. This was achieved by conducting spectroscopy IR and differential scanning calorimetry tests.
