Low-cost, 8-bit, single-chip microcontrollers are stingy when it comes to on-chip PWM (pulse-width-modulation) resources. The use of a PWM resource often forces a designer to sacrifice a ...

LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim’s ICL7660, but that ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Atmel(R) Corporation (Nasdaq: ATML), a global leader in the development and fabrication of advanced semiconductor solutions, announced today the availability of the new ATA6831 driver IC with enhanced ...

IRVINE, Calif.--(BUSINESS WIRE)--Toshiba America Electronic Components, Inc. (“Toshiba”) has launched the “TB67B000AHG,” a new three-phase brushless motor driver for home appliances such as ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

Back in October I was pondering the creation of accurate micro-voltages from a microcontroller. What makes this so difficult is the voltage offset created by current in the microcontroller bond wire, ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

[Hugatry] wanted to replace the adjustment pot on an LM2596 buck converter with a microprocessor-controlled voltage. The regulator IC uses a divider to generate a 1.25V reference from the output. The ...

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple ...
