Supplied in a small 24-pin leadless WQFN package with dimensions of 4x4x0.75mm, Toshiba’s TB67H301FTG reduces the mounting area to one third that of equivalent products. This contributes to reducing the size of equipment and also reducing PCB cost.
Although significantly smaller than products offering similar functionality, the motor driver IC’s WQFN24 package offers good thermal conductivity. The full-bridge DC motor driver IC also realises the same absolute maximum ratings for voltage (40V for the motor and 6V for the control) and current value (3A) as equivalent products. The operating ranges for the power supply voltage for the motor are 4.5-38V; and for control are 3-5.5V.
Additionally, the TB67H301FTG incorporates overcurrent shutdown circuit protection, under voltage lockout circuit protection and thermal shutdown circuit protection. Other features include forward/reverse/short brake/stop function and PWM constant-current control.
