The potentiometer portion of a mixed-signal, digitally programmable potentiometer adds variability to an analog circuit, and its digital controls provide programmability. You can use a digital potentiometer in two ways in an analog circuit. You can ...
Rex Niven EDN The ubiquitous LCD (Figure 1) (and VFD) modules based on the HD44780 controller IC can require up to 12 lines from the host. Figure 1. A typical LCD module. This hardware interface Design Idea (Figure 2) reduces the connection to just ...
Čestmír Hýbl elbastl.sweb.cz Introduction Some time ago I was poking in my box of old components. I was searching something else, but I stopped when a few of nixies came up into my hand. Once upon a time (a long, long time ago) I ...
Kahou Wong, On Semiconductor EDN A buck/boost converter can step a voltage up or down. Such a converter is appropriate for battery-powered applications. One application derives a regulated 14.1 V at 1 A from 12 V solar panels with 9 to 18 V ...
Ricardo Jiménez and Juan C. Ángeles Electronic Design A basic microcontroller can be used to convert a sensor's analog output into a pulse train, thereby making the output compatible with standard digital I/O ports. When the need ...
A basic combination of a photovoltaic panel, multiple LEDs, and a small dc-dc regulator can provide light in dark corners while also offering a modest auxiliary dc-power rail. A solar-powered, daytime-only lamp without a battery for energy storage ...
Application Note ANDNGTB30N60L2WG/D June 2014 NGTB30N60L2WG newly developed is one of FS2-IGBT series, which enables fast switching and low VCE(sat) at the same time. It is considered common to take the absolute maximum Ic rating as reference when ...
Application Note AND9140/D December 2013 IGBTs generally require a more complex set of calculations to determine the die temperatures than do most power semiconductors. This is due to the fact that most IGBTs are co-packaged and include both an ...
Design Note DN05058/D December 2013 This design note describes a very simple, low power, constant voltage output buck power converter intended for powering electronics for white goods, electrical meters, and industrial equipment where isolation ...
Application Note ANDLV8136V/D December 2013 The LV8136V is a PWM system pre-driver IC designed for three-phase brushless motors. This IC reduces motor driving noise by using a high-efficiency, quiet PWM drive (150-degree drive system). It ...
