Single Phase Full-wave Driver for Fan Motor

TC78B002FTG is a single phase full-wave driver for fan motor. It has a DMOS device in an output transistor.
A highly effective drive is possible by adopting a DMOS output driver with low ON resistance and a PWM drive system.

FEATUREs
• Single-phase full-wave drive
• Motor power supply voltage: VM =16V (maximum operating range)
• Output current: Iout = 1.5A (max.)
• PWM control
• Built-in oscillation circuit (External resistor)
• Soft switching drive
• Lock protection, Automatic recovery
• Quick start
• Built in hall bias
• Rotation Speed Detection (FG) and Lock Detection (RDO) Output
• Current limit function
• Built in over current protection
• Built in thermal shut down circuit
