Full-Bridge Driver IC for DC Motors
The TB6549F/FG/P/PG/HQ is a full-bridge driver IC for DC
motors that uses an LDMOS structure for output transistors.
High-efficiency drive is possible through the use of a MOS
process with low ON-resistance and a PWM drive system. Four
modes, CW, CCW, short brake, and stop, can be selected using
IN1 and IN2.

Note: This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product,
ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive
mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at
reasonable levels.
