Motor-driver IC shuts down to 100 nA standby current

December 18, 2013 // By Graham Prophet
TB67H301FTG is a full-bridge DC motor driver IC 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.

A standby function reduces standby mode current to 0.1µA or less. The device comes in a leadless WQFN24 package with dimensions of 4.0 x 4.0 x 0.75 mm. This reduces the mounting area to one third that of equivalent products; the TB67H301FTG’s WQFN24 package maintains thermal conductivity and has the same absolute maximum ratings for voltage and current value as equivalent products (40V/6V: 3.0A). 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.

TB67H301FTG 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.
