GENERAL DESCRIPTION
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
indication, ILMT, is provided to indicate an over-current
condition.
The RPM output gives an indication of motor RPM.
Each time the motor current is interrupted by commutation,
a logic pulse occurs on RPM. The fundamental frequency
of the resulting square wave is (4 x rpm). See the
Applica-
tions section for more information and system design
guidelines.
The TC643 mates easily with microcontrollers or other
digital logic to form a complete motor or fan control and
monitoring system, featuring: Variable Speed PWM
Drive; RPM Indication; and Motor Open / Motor Shorted
/ Motor Locked Fault Detection.
The TC643 is available in a standard 8-pin plastic DIP,
SOIC, and MSOP package.
