Toshiba Bi-CD Integrated Circuit Silicon Monolithic TB6612FNG 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, Weight: 0.14 g (typ.) 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. © 2014 TOSHIBA Corporation 1 2014-10-01
