The LS7362 is a MOS integrated circuit designed to gener- ate the signals necessary to control a three phase or four phase brushless DC motor. It is the basic building block of a brushless DC Motor Controller The circuit responds to changes at the SENSE inputs, originating at the motor po- sition Sensors to provide electronic commutation of the motor windings. Pulse width modulation (PWM) of low-side drivers for motor speed control is accomplished through ei- ther the ENABLE input or through the V TRIP input (Analog Speed control) in conjunction with the Oscillator input. Overcurrent circuitry is provided to protect the windings, as- sociated drivers and power supply. The LS7362 circuitry causes the external output drivers to Switch off immediately upon sensing the overcurrent condition, and on again only when the overcurrent condition disappears and the positive edge of either the ENABLE input or the sawtooth OS- CILLATOR occurs. This limits the overcurrent sense cy- cling to the chopping rate of the ENABLE input or the saw- tooth Oscillator A positive braking feature is provided to effect rapid deceleration. The LS7362 is designed for driving Bipolar and Field Effect Transistors Because only low-side drivers are pulse width modulated, the LS7362 is ideally suited in situations where the integrated circuit inter- faces with level converters to drive high voltage brushless DC motors. By pulse width modulating the low-side drivers only, the Switch losses in the level conversion circuitry for the high-side drivers is minimized. Figure 1 indicates how the level conversion is accomplished. By LSI Computer Systems, Inc.
