Brushless Motor Control
Anaheim Automation's Brushless Motor Controller IC Chip are MOS integrated circuits designed to generate the signals necessary to control a three phase or four phase Brushless DC Motor. They are the basic building blocks of a Brushless DC Motor Controller.
* Open or Closed loop motor speed control
* Externally selectable input to output code for 60°, 120°, 240°, or 300° electrical sensor spacing.
* Three or Four Phase operation
* Overcurrent Sensing
* Analog Speed control
* +5v to +28v operation (Vss - Vdd)
* Direction Control.
10 piece minimum order.

The IC Chip 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. The IC Chip operates from 10v to 18v and provides CMOS compatible outputs for interfacing with external power devices.

While the LSI-LS7362C is designed for driving NPN and PNP transistors. The LSI-LS7362C offers the same features as the LSI-LS7262 except the Pulse Width Modulation occurs only in low-side drivers allowing use with High-Voltage motors.
