Pre-driver ICs are quiet for domestic use
Eight single-phase BLDC motor pre-driver ICs from Toshiba are designed for high-current cooling fan applications such as PC servers and home appliances, including fridges. The TC78B006 ICs reduces vibration and noise by using a digital-control-type sine wave drive. Integrated pre-drive circuitry enables the ICs to drive external p-channel and n-channel MOSFETs and minimise the number of external components needed. Power consumption is reduced by cutting power supply to the Hall element, a magnetic sensor used to detect rotor position and rotation speed, whenever the motor is in standby mode. The TC78B006FNG, TC78B006AFNG, TC78B006FTG and TC78B006AFTG ICs feature PWM duty input control. The TC78B006BFNG, TC78B006CFNG, TC78B006BFTG and TC78B006CFTG offer analogue voltage input control. Rotation speed direction output is featured on the FNG, BFNG, FTG and BFTG ICs, while the AFNG, CFNG, AFTG and CFTG offer lock detection output. All operate from 3.5 to 30V, and have quick start function, thermal shutdown, lock protection and auto-restart. Two package types are offered: a 16pin SSOP measuring 5.5 × 6.4 x 1.6mm, for the FNG, AFNG, BFNG and CFNG ICs or 16pin QFN, measuring 3 × 3 × 0.7mm for the FTG, AFTG, BFTG and CFTG. Samples are available now.
