Brushless Motor Controller - LSI-LS7561N

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. Note: This series has a minimum purchase requirement of 10 pieces, regardless of stock.
