The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...

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 ...

In a speed controller, the motor’s speed (or velocity) is being controlled. There is an element that detects speed, whether it be a tachometer or some sort of encoder. This monitoring element provides ...

Designed with a bridge-tied-load (BTL) drive architecture in order to reduce audible switching noise and electromagnetic interference (EMI), the AM9468 and AM9469 brushless DC motor drivers from ...

motor control based on a six-step commutation sequence; detection of the magnetic angle of the rotor, to perform the commutation at the correct angle (each step corresponds to an angle of 60 degrees); ...
