TB6569FG/FTG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6569FG/FTG Full-Bridge DC Motor Driver IC The TB6569FG/FTG is a full-bridge DC motor driver with MOS output transistors. The low ON-resistance MOS process and PWM control enables driving DC motors with high thermal efficiency. Four operating modes are selectable via IN1 and IN2: clockwise (CW), counterclockwise (CCW), Short Brake and Stop. Features Power supply voltage : 50 V (max) TB6569FG:Weight: 0.5 g (typ.) Output current : 4.5 A (max) Direct PWM control PWM constasnt-current control CW/CCW/Short Brake/Stop modes Overcurrent shutdown circuit (ISD) Overcurrent detection threshold control Overcurrent detection time control Overvoltage shutdown circuit (VSD) P-VQFN32-0505-0.50-002 Thermal shutdown circuit (TSD) Undervoltage lockout circuit (UVLO) TB6569FTG:Weight: 0.07 g (typ.)
