Toshiba TB67H420FTG surface-mount brushed motor driver IC

Toshiba Electronic Devices & Storage Corporation has broadened its line-up of small surface-mount brushed motor drivers with the TB67H420FTG. A high-voltage, large-current drive is achieved with Toshiba’s 130 nm process technology, making the product suitable for robot vacuum cleaners, printers and other office equipment.

The device can control two brushed motors as it incorporates a dual-bridge mode that can control each channel independently in the separated internal output unit. The built-in function of switching single-bridge mode (ultra large-current drive of 9 A) and dual-bridge mode (large-current drive of 4.5 A/two channels) allows use in diverse applications.

The unit contributes to space saving by adopting a small surface-mount package. Heat generation during motor driving is meanwhile reduced by ultralow on-resistance. Packaging in a small and high-heat-radiation QFN package allows users to simplify set and module heat dissipation design.

A motor load open detection function has been incorporated, in addition to thermal shutdown, overcurrent protection and undervoltage lockout. Error status can be flagged to external devices by an error flag function, strengthening safety safeguards.
