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 amplifier for closed loop motor speed control, a
PWM comparator and sawtooth oscillator for external driver
power control and a 6V reference generator for supplying power
to motor sensors. Also included is Fault detection and indication,
overcurrent sensing, dynamic motor braking, forward/
reverse input, sensor spacing selections and an enable input
control. This series has a minimum purchase requirement of 10 pieces, regardless of stock.
NOTE: LSI-LS7560N-S and LSI-LS7561N are Limited to Stock on Hand.
NOTE: LSI-LS7560N and LSI-LS7560N-TS are NRND (Not Recommended for New Designs)
