- Realize low noise and high efficiency with sine wave drive -

TOKYO — (BUSINESS WIRE) — January 29, 2015 — Toshiba Corporation (TOKYO:6502) today announced the launch of new single-phase fan motor pre-driver ICs, the TC78B006 series, for the cooling fans of PC servers and home appliances, such as refrigerators. Sample shipments start today.

The new ICs can be applied to high current applications with built-in pre-drive circuit to drive external MOSFETs. They implement the same sine-wave-driven function^[1] as the current “TC78B002 series” to realize quiet operation, and a standby function to reduce power consumption when the fan motor is not in operation contributes to power saving operation.

Main Features of New Products

• Quiet operation
  Vibration and noise of the motor are reduced by the digital-control-type sine wave drive.
• Power saving
  The standby function reduces power consumption of the entire motor set by cutting power supply to the Hall element^[2] when the motor is in standby mode.
• Built-in pre-drive circuit
  Pre-drive circuits necessary to drive the external Pch MOSFET and Nch MOSFET are built in. Pch-Nch MOSFET can be driven with fewer external components.
