DUAL-BRIDGE DRIVER IC FOR DC MOTORS
The TB6552FN/FNG/FL/FLG is a dual-bridge driver IC for DC
motors with output transistors in an LD MOS structure with low
ON-resistance. Two input signals, IN1 and IN2, can chose one of
four modes such as CW, CCW, short brake, and stop mode. A
PWM drive system supports high heat efficiency driving.
Features
• Power supply voltage for motor: VM ≤ 15 V (max)
• Power supply voltage for control: V_CC = 2.7 V to 6.0 V
• Output current: 1 A (max)
• Low ON resistor: 1.5 Ω (typ.)
(Upper side + lower side combined @ VM = 5 V)
• Direct PWM control
• Standby system (power saving)
• CW/CCW/short brake/stop function modes
• Built-in thermal shutdown circuit
• Package: SSOP16 for TB6552FN/FNG /QON24 for

* 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.
