The Toshiba TC78B027FTG,EL is a silicon monolithic integrated circuit designed as a 1-Hall sine-wave PWM pre-driver for 3-phase brushless DC motors. It supports external N-channel MOSFETs and incorporates non-volatile memory (NVM) and closed-loop speed control functions, eliminating the need for microcontrollers and reducing costs.
Key features include a configurable speed curve, adjustable driving current for external MOSFET gates, and a serial interface. The device operates within a voltage range of 5V to 16V, with electrical characteristics guaranteed from 9V to 16V. It also includes a standby mode, soft start, and outputs RPM information.
Protection features are integrated to ensure reliability, including Thermal ShutDown (TSD), Under Voltage LockOut (UVLO), Over Voltage Protection (OVP), under voltage protection for the charge pump, Over Current limit Protection (OCP), over current protection (ISD), and lock detection.
The TC78B027FTG,EL is available in a 24-VQFN (4x4) package and is surface-mountable. Its operating temperature range is -40°C to 105°C (TA). This controller is suitable for applications such as server fan motors.
