Toshiba TB67H450AFTG PWM Chopper DC Brushed Motor Driver
Toshiba TB67H450AFTG PWM Chopper DC Brushed Motor Driver is designed for a wide range of general-purpose motor control applications. Housed in a compact 16-pin VQFN package, the Toshiba TB67H450AFTG supports a single-channel output with a maximum output voltage of 50V and a peak output current of 3.5A, suitable for driving medium-power motors. Built using Toshiba’s BiCD process, the TB67H450AFTG integrates multiple protection features, including under-voltage lockout (UVLO), overcurrent shutdown (ISD), and thermal shutdown (TSD), ensuring robust and reliable operation. This device supports various drive modes such as forward (CW), reverse (CCW), short brake, and stop, and includes a standby function for power-saving operation. TB67H450AFTG is ideal for applications requiring precise motor control with efficient thermal and electrical protection.
