LS7561N controller equivalent, brushless dc motor controller.
* Open loop motor control
* Tachometer output for closed loop motor control
* Error Amplifier and PWM Speed Comparator with full accessibility
* High nois.
The LS7560N/LS7561N are designed to control three or four phase brushless DC motors in a closed or open loop configuration. The IC consists of a decoder which provides proper commutation sequencing, a frequency-to-pulse width converter and error ampl.
