Additional Infomation About Product

TB6643KQ TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6643KQ Full-Bridge DC Motor Driver IC The TB6643KQ 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: 4.5 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 Note: The following conditions apply to solderability: About solderability, following conditions were confirmed (1) Use of Sn-37Pb solder Bath solder bath temperature: 230C dipping time: 5 seconds the number of times: once use of R-type flux (2) Use of Sn-3.0Ag-0.5Cu solder Bath solder bath temperature: 245C dipping time: 5 seconds the number of times: once use of R-type flux 1 2011-06-21 TB6643KQ Block Diagram (application circuit example) The application circuits shown in this document are provided for reference purposes only.
