A full-bridge DC motor driver IC incorporating a standby function has been announced by Toshiba Electronics Europe (TEE) that is claimed to realises power supply 
current in standby mode of 0.1µA or less. The company advises its TB67H301FTG is designed for use in industrial and consumer equipment where extending battery life or time between charging is important. Typical applications are expected to include printers, vending machines and home appliances.
The company explains, this device utilises a small, leadless WQFN24 package with dimensions of 4.0 by 4.0 by 0.75mm to reduce the mounting area to one third that of equivalent products.
The company points out, although significantly smaller than products offering similar functionality, the package of this device offers good thermal conductivity and realises the same absolute maximum ratings for voltage and current value as equivalent products (40V/6V: 3.0A). It addsthat, the operating ranges for the power supply voltage for the motor are 4.5 to 38V; and for control are 3.0 to 5.5V.
The company advises the design package incorporates an overcurrent shutdown circuit, under voltage lockout circuit and thermal shutdown circuit. Other features include forward/reverse/short brake/stop function and PWM constant-current control.
