Description (continued)
torque control, allowing the internal current control circuit to set
the maximum current limit.
Efficiency is enhanced by using synchronous rectification. The
power FETs are protected from shoot-through by integrated
crossover control with dead time. The dead time can be set by a
single external resistor.
The A3930 and A3931 only differ in their response to the all-zero

combination on the Hall inputs. In this state, the A3930 indicates
a logic fault, but the A3931 pre-positions the motor in an unstable
starting position suitable for start-up algorithms in microprocessor-
driven “sensor-less” control systems.
Both devices are supplied in a 48-pin LQFP with exposed thermal
pad. This is a small footprint (81 mm
(Pb) free, with 100% matte tin leadframe plating.
