TOKYO, June 22 (Bernama-BUSINESS WIRE) -- Toshiba Corporation's (TOKYO:6502) Storage & Electronic Devices Solutions Company today announced the launch of the three-phase brushless motor drivers "TC78B015FTG" for 12V power supply and "TC78B015AFTG" for 24V power supply. The new ICs support high speed rotation of small fan motors suited to home appliances and industrial equipment. Mass production starts today.
Ideally, cooling fans, such as server fans, combine minimized size with a high rotation speed that ensures a high cooling capability. Toshiba's new products adopt small packages that can be mounted on the limited board space of small motors. They also reduce the external component count with a one-sensor drive and current detection resistor-free system. One-sensor driving secures more reliable motor operation than a sensorless drive and reduces the number of hall sensors from three (required for a 3-sensor drive) to one. The current detection resistor-free system can reduce rated power supply and eliminate the large resistors previously required. These all contribute to reduced demand for space on wiring boards.
