This brushless motor driver targets applications requiring up to one-third horsepower and allows engineers the choice of either a DSP or an MCU digital interface. The unit's three independent half-bridges deliver up to 5A output current or 10A peak using industrial voltage supplies of 60V. Independent access to each of the six MOSFETs allows PWM control and commutation for three high-current outputs. Protection circuitry includes three-phase current monitoring, temperature monitoring, and prevention of shoot-through currents and activating both the top and the bottom MOSFETs in the same phase. The driver allows the use of smaller filter components by switching at frequencies up to 100 kHz. Offered in a 23-pin staggered-lead IC package, with a grounded case for easy heat-sinking, the SA305 operates over a temperature range of -40 to 85C.
