Full-Bridge Driver IC for DC motor
TB6549F/P is a full-bridge driver IC for DC motor which uses
LDMOS for output transistors. High efficient drive is possible by
MOS process with low ON-resistor and PWM drive system. Four
modes such as CW, CCW, short brake, and stop can be chosen by
IN1 and IN2.
Features
• Power supply voltage: 30 V (max)
• Output current: 3.5 A (max)
• Low ON resistor: 0.5 Ω (typ.)
• Capable of PWM controlling
• Standby system
• CW/CCW/short brake/stop function modes.
• Built-in overcurrent protection
• Built-in thermal shutdown circuit
• Package: HSOP-20/DIP-16

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.
