A current sensor with PWM output is a very useful type of device. Traditionally, the device can serve in a digital application where the host microcontroller can determine the ratio of the on-time to ...
This technical document discusses a simple method of converting a PWM output signal into an analog output signal employing a Hall effect sensor or PWM sensor. This article covers the behavior of PWM ...
This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...
Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...
Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...
Linear Technology Corporation introduces the LTC2645, a quad-channel 12-bit/10-bit/8-bit PWM-to-voltage output digital-to-analog converter (DAC) with 10ppm/°C reference. Linear Technology Corporation ...
Toshiba has expanded its family of three-phase brushless motor driver ICs which integrate motor speed control, sine wave PWM output, real-time automatic lead angle correction, and gate driver ...
Texas Instruments has introduced a pair of closely-related dual-output PWM dc-dc converter controllers for space applications, one radiation-hardened and the other radiation tolerant. Both can operate ...
PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...
