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
