TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB67H400AFTG TB67H400AFTG PWM Chopper-Type Brushed DC Motor drive r The TB67H400AFTG is brushed DC motor driver of a PWM chopper-type. The TB67H 400AFTG is a dual channel H-SW driver w hich can control two brushed DC motors. Moreover, the parallel control functio n (Large mode) of an output part is bui lt in, and 1ch high current drive is al so possible. Fabricated with the BiCD p rocess, the TB67H400AFTG is rated at 50 V, 4.0 A (2ch)/8.0 A (1ch). Features Monolithic motor driver using BiCD p rocess.  Capable of controlling two brushed DC motor.  2 drive modes (PW M controlled constant current/

direct PWM)  4 operation modes (Clock -wise/Counter clock-wise/Brake/Stop (Of f))  Low on-resistance output stage (High side+Low side:0.49 Ω (typ.))  High voltage and current (for specific ation, please refer to absolute maximum ratings and operating ranges.)  Bui lt-in error detection circuits (Thermal shutdown (TSD), over-current detection (ISD), and power-on reset (POR)).  The VCC regulator for internal circuit operation is built in.  Able to cust omize PWM (internal chopping) frequency by external components. Note: Please b e careful about the thermal conditions during use.
