DescriptionCombining logic and power, the UDN2936W and UDN2936W-120 provide commutation 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. These drivers also feature internal commutation logic, PWM current control, and thermal shutdown protection.
The UDN2936W and UDN2936W-120 are compatible with singleended digital or linear Hall effect sensors. The commutating logic is programmed for 60° (UDN2936W) or 120° (UDN2936W-120) electrical separation. 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/W-120 also include braking and direction control. Internal protection circuitry prevents crossover current when braking or changing direction.
Both devices are 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 and UDN2936W-120 are supplied in 12-pin single in-line power-tab packages. An external heat sink may be required for high-current applications. The tab is at ground potential and needs no insulation.
