TB6612FNG 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. Features ? Power supply voltage: VM = 15 V(Max) ? Output current: IOUT = 1.2 A(ave)/3.2 A (peak) ? Output low ON resistor: 0.5Ω (upper+lower Typ. @ VM ≥ 5 V) ? Standby (Power save) system ? CW/CCW/short brake/stop function modes ? Built-in thermal shutdown circuit and low voltage detecting circuit ? Small faced package(SSOP24: 0.65 mm Lead pitch) * 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.
