Toshiba Bi-CD Integrated Circuit Silicon Monolithic
TB6612FNG
Driver IC for Dual DC motor
TB6612FNG is a driver IC for DC motor with output transistor in
LD MOS structure with low ON-resistor. Two input signals, IN1
and IN2, can choose one of four modes such as CW, CCW, short
brake, and stop mode.

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.
