TOKYO — (BUSINESS WIRE) — January 30, 2019 — Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has started sample shipments of “TB9058FNG,” an automotive DC motor driver IC with a LIN (Local Interconnect Network) slave function that can communicate with a LIN 2.0 master IC for in-vehicle networks. The new IC is suitable for the diverse applications that use the LIN BUS with 0.3A output current, including heating, ventilation and air conditioning (HVAC) damper control drivers. Mass production will start in December 2019.

The new IC receives the position data of the motor rotation target by an external LIN BUS, and drives the motor to the rotation target.
No software development is required, as the IC has the hardware logic of a H-bridge motor driver and LIN communication function with enhanced checksum. It can detect over voltage, over current and over temperature thereby prevent abnormal operating conditions.
The new IC has an operating temperature range of -40 to 125°C, required for automotive applications, and will be AEC-Q100 qualified.
Simple control by full hardware logic
- No need to develop software. Motor control by LIN communication.
