GENERAL DESCRIPTION

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. The overcurrent sense condition will disable all output drivers when using the LS7560N and only the bottom drivers when using the LS7561N.
