The TC78B006 series reduces vibration and noise by using a digitally controlled sine wave drive.
The integrated pre-drive circuit allows the device to control p-channel and n-channel MOSFETs, minimizing the number of external components required to control the motors.
A power-saving standby function reduces energy consumption by decreasing the power supply to the Hall element, a magnetic sensor used to detect rotor position and rotational speed, whenever the motor is in standby mode.
Within the TC78B006 series, the TC78B006FNG, TC78B006AFNG, TC78B006FTG, and TC78B006AFTG ICs feature PWM duty cycle input control, while the TC78B006BFNG, TC78B006CFNG, TC78B006BFTG, and TC78B006CFTG offer analog voltage input control.
Rotational speed direction output is provided by the FNG, BFNG, FTG, and BFTG ICs, while the AFNG, CFNG, AFTG, and CFTG offer lock-up detection output. The entire TC78B006 series offers an operating voltage of 3.5–30 V, fast start functionality, thermal shutdown, lock-up protection, and auto-reset.
The TC78B006 series is available in two package types: a 16-pin SSOP measuring 5.5 mm × 6.4 mm × 1.6 mm for the FNG, AFNG, BFNG, and CFNG ICs, or a 16-pin QFN measuring 3 mm × 3 mm × 0.7 mm for the FTG, AFTG, BFTG, and CFTG. Samples are already available. Mass production begins in February.
