TB6552FNG/FTG Toshiba Bi-CD Integrated Circuit Silicon Monolithic TB6552FNG, TB6552FTG DUAL-BRIDGE DRIVER IC FOR DC MOTORS The TB6552FNG/FTG is a dual-bridge driver IC for DC motors TB6552FNG with output transistors in an LD MOS structure with low ON-resistance. Two input signals, IN1 and IN2, can choose one of four modes such as CW, CCW, short brake, and stop mode. A PWM drive system supports high heat efficiency driving. Features Power supply voltage for motor: VM 15 V (max) Power supply voltage for control: V = 2.7 V to 6.0 V CC TB6552FTG Output current: 1 A (max) Low ON resistor: 1.5 (typ.) (Upper side + lower side combined VM = 5 V) Direct PWM control Standby system (power saving) CW/CCW/short brake/stop function modes Built-in thermal shutdown circuit P-WQFN16-0303-0.50-0.01 Package: FNG-SSOP16/FTG-WQFN16 Weight SSOP16-P-225-0.65B : 0.07 g (typ.) P-WQFN16-0303-0.50-0.01 : 0.017 g (typ.) * 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 TB6552FNG/FTG Block Diagram V BIN1 BIN2 BPWM BSTBY BO1 BO2 VM CC Control logic (Ch.
