LSI-LS7560N | Anaheim Automation, Inc.

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 river 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.

Note: This series has a minimum purchase requirement of 10 pieces, regardless of stock. LSI-LS7561N is Limited to Stock on Hand. LSI-LS7560N and LSI-LS7560N-TS are NRND (Not Recommended for New Designs).
