3-PHASE BRUSHLESS DC MOTOR
CONTROLLER/DRIVER
Combining logic and power, the UDN2936W-120 provides com-
mutation and drive for three-phase brushless dc motors. Each of the
three outputs are rated at 45 V and ±2 A (±3 A peak), and include
internal ground clamp and flyback diodes. The driver also features
internal commutation logic, PWM current control, and thermal shut-
down protection.
The UDN2936W-120 is compatible with single-ended digital or
linear Hall effect sensors. The commutating logic is programmed for
120° electrical separation. The UDN2936W-120 can replace the
original UDN2936W (60° electrical separation) by simply adding an
inverter at the H2 input. Current control is accomplished by sensing
current through an external sense resistor and pulse-width modulating
the source drivers. Voltage thresholds and hysteresis can be externally
set by the user. If desired, internal threshold and hysteresis defaults
(300 mV, 7.5 percent) can be used. The UDN2936W-120 also includes
braking and direction control. Internal protection circuitry prevents
crossover current when braking or changing direction.
The UDN2936W-120 is also available for operation between -40°C
and +85°C. To order, change the prefix from ‘UDN’ to ‘UDQ’.
For maximum power-handling capability, the UDN2936W-120 is
supplied in 12-pin single in-line power-tab package. An external heat
sink may be required for high-current applications. The tab is at
ground potential and needs no insulation.
