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)

• 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

TB6552FL/FLG

* 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.
