BLDC Motor Commutator/Controller…. (20 Pins) LS7262, LS7262-S, LS7262-TS Open or closed loop control of 3 and 4 phase motors HALL SENSOR inputs control output commutation sequence for electrical sensor spacings of 60°, 120°, 240°, or 300° Speed controlled by Pulse Width Modulation of output drivers Control inputs include ANALOG SPEED, FORWARD/REVERSE, OUTPUT ENABLE and POSITIVE STATIC BRAKING OVERCURRENT SENSING disables output drivers Direct drive of FETs and Bipolar Transistors 5V to 28V operation   BLDC Motor Commutator/Controller…. (20 Pins) LS7362, LS7362-S, LS7362-TS Same features as LS7262 except Pulse Width Modulation occurs only in low-side drivers allowing use with High-Voltage motors     BLDC Motor Controller…. (28 Pins) LS7560N, LS7560N-S, LS7560N-TS; LS7561N, LS7561N-S, LS7561N-TS Single-Chip Open or Closed Loop Motor Controller LS7560N, LS7561N are backwards compatible to LS7560, LS7561, respectively User Selectable Features Include: PWM of All Drivers or Low-Side Drivers Only Polarity of High Side Drivers Static or Dynamic Braking 60°/300° or 120°/240° Electrical Sensor Spacing   Level-Sensitive ENABLE Cycle-by-Cycle Overcurrent Sensing Overcurrent Condition Disables All Drivers (LS7560N) or Low-Side Drivers Only (LS7561N) Fault LED Indicator Output 10V to 18V Operation
