TOSHIBA BEGINS MASS PRODUCTION OF GATE DRIVER IC FOR AUTOMOTIVE DC MOTORS 

KUALA LUMPUR, March 13 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has commenced mass production of the "TB9103FTG", a gate driver integrated circuit (IC) designed for automotive brushed DC motors.

According to a statement, this includes latch motors and lock motors for power backdoors and power slide doors, as well as drive motors for power windows and power seats.

With the shift to electrified automotive parts, the demand for electric motors and their drivers has increased, prompting the need for more compact, integrated solutions.

The TB9103FTG offers streamlined gate driver capabilities for brushed DC motors that do not require speed control, enabling a more compact design. It features a built-in charge pump circuit that ensures adequate voltage to power external MOSFETs for motor operation.

Additionally, it incorporates a gate monitoring function to prevent through-current by automatically controlling the output timing of the gate signal to the high-side and low-side external MOSFETs.

The IC is also equipped with a sleep function, reducing power consumption in standby mode. It can be utilised as a one-channel H-bridge or a two-channel half-bridge configuration.

Beyond motor driver applications, it can be integrated with an external MOSFET to replace mechanical relays and switches, contributing to quieter operation and enhanced reliability.

Toshiba reaffirmed its commitment to expanding its range of automotive motor drivers, supporting the electrification and enhanced safety of automotive systems.
