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) Weight: 0.14 g (typ.) Output current: I = 1.2 A(ave)/3.2 A (peak) OUT Output low ON resistor: 0.5 (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. 2014 TOSHIBA Corporation 1 2014-10-01 TB6612FNG Block Diagram Pin Functions No. Pin Name I/O Function 1 AO1 O ch A output 1 2 AO1 3 PGND1 Power GND 1 4 PGND1 5 AO2 O ch A output 2 6 AO2 7 BO2 O ch B output 2 8 BO2 9 PGND2 Power GND 2 10 PGND2 11 BO1 O ch B output 1 12 BO1 13 VM2 Motor supply 14 VM3 15 PWMB I ch B PWM input/200 k pull-down at internal 16 BIN2 I ch B input 2/200 k pull-down at internal 17 BIN1 I ch B input 1/200 k pull-down at internal 18 GND Small signal GND 19 STBY I L = standby/200 k pull-down at internal 20 Vcc Small signal supply 21 AIN1 I ch A input 1/200 k pull-down at internal 22 AIN2 I ch A input 2/200 k pull-down at internal 23 PWMA I ch A PWM input/200 k pull-down at internal 24 VM1 Motor supply 2 2014-10-01
