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.
