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.
High speed rotation is achieved with a 150-degree commutation
system. Rotation is faster and more stable than with a sine-wave
commutation system, and vibration is lower than in a conventional
120-degree commutation system. Adoption of low on-resistance (upper
+ lower: 0.24Ω (typ.)) ensures suppression of heat generated from
increased motor current by a high frequency drive, realizing
support of a large current drive of up to 3A.
Main Features of New Products
- Small packageWQFN 36 (5mm x 5mm x
0.8mm) package that can be mounted on the limited board space of
small fans.
- Space saving for boardsOne-sensor drive
and current detection resistor-less system save space previously
required for mounting external components.
- High speed rotationA 150-degree
commutation system realizes faster and more stable rotation than a
sine-wave commutation system and lower vibration than a 120-degree
commutation system.
- Low lossIC loss during motor operation
can be suppressed by low on-resistance of 0.24 Ω (typ.).
