TB67H301FTG

TB67H301FTG TOSHIBA Bi-CDMOS Integrated Circuit Silicon Monolithic TB67H301FTG Full-Bridge DC Motor Driver IC The TB67H301FTG is a full-bridge DC motor driver with DMOS output transistors. The low ON-resistance DMOS 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 : 40 V (max) Output current : 3 A (max) Direct PWM control PWM constasnt-current control CW/CCW/Short Brake/Stop Overcurrent shutdown circuit (ISD) Thermal shutdown circuit (TSD) Undervoltage lockout circuit (LVD) Dead time for preventing shoot-through current P-WQFN24-0404-0.50-004: Weight: 0.036 g (typ.) © 2014 TOSHIBA Corporation 1 2014-10-01 TB67H301FTG Block Diagram (application circuit example) The application circuits shown in this document are provided for reference purposes only.
