TB6568KQ,8 Toshiba

TB6568KQ TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6568KQ Full-Bridge DC Motor Driver IC The TB6568KQ is a full-bridge DC motor driver IC employing the MOS process for output power 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) Weight: 2.2 g (typ.) Output current: 3 A (max) Output ON-resistance: 0.55 (typ.) PWM control CW/CCW/Short Brake/Stop modes Overcurrent shutdown circuit (ISD) Overvoltage shutdown circuit (VSD) Thermal shutdown circuit (TSD) Undervoltage lockout circuit (UVLO) Dead time for preventing shoot-through current 1 2017-04-14 2014 TOSHIBA Corporation TB6568KQ Block Diagram (application circuit example) The application circuits shown in this document are provided for reference purposes only.
