Toshiba Corporation today announced that it has expanded its line-up of digital-control and sinusoidal-wave fan motor driver ICs with the launch of the TC78B002FNG, available in an SSOP16 package. The new driver IC has an operating voltage range of 3.5 to 16 V and a maximum output current of 1.5A. The new IC is the latest addition to the company's TC78B002-series and designed for use in home appliances, such as refrigerators, and PCs. Mass production shipments start on February 21.
Features of the TC78B002FNG include: Soft switching drive (sinusoidal-wave drive capable); Boot sequence; Lock protection, Automatic recovery; Quick start; Current limiter, Thermal shutdown circuit, and Monitoring of low power supply voltage; and Regulator circuit 5V (Typ.) / 10mA (Max.). The TC78B002-series incorporates an original digital control circuit that realizes sinusoidal control of the motor current, improving motor efficiency while reducing noise.
The new product adopts an SSOP16 package while offering the same features as the TC78B002FTG, already in mass-production, allowing customers to apply low-cost solder flow assembly. This allows manufacturers to bring down production costs by using single-layer PCBs instead of high cost double-layer PCBs.
