TC643, INTEGRATED FAN / MOTOR DRIVER
The TC643 is a switchmode brushless DC fan/motor speed driver with diagnostic circuits.
External components are kept to a minimum by integrating the power transistor on chip.
Any logic-level signal can be used to drive the on-chip Power Driver.
The output is current limited and a logic-level indica
