Toshiba Electronics is providing engineering samples of its TB9084FTG, a MOSFET gate driver IC for three-phase brushless dc (BLDC) motors with a power rating of several hundred watts.
The new device supports the trend of automotive OEMs replacing brushed dc motors with quieter, longer-lasting BLDC motors to drive body system applications like powered sliding passenger doors, power tailgates, and adjustable seats.
The device can also drive BLDC motors to enhance the power performance of electric pumps and fans.
The key features of the gate driver IC include a six-channel gate-driver structure, an additional gate-driver output for controlling an external MOSFET for reverse polarity protection, a built-in operational amplifier for motor current sensing, SPI communication, and an emergency motor stop function.
The IC also integrates robust protection circuitry, including power supply under-voltage detection, charge pump overvoltage detection, thermal shutdown, and MOSFET drain-source voltage (VDS) monitoring, ensuring reliable operation under demanding conditions.
The IC supports equipment miniaturization and is housed in a compact 6mm × 6mm P-VQFN36-0606-0.50 package. It operates within a wide temperature range (-40° to +150° C) and meets the AEC-Q100 (Grade 0) automotive standard. Additionally, its wettable flank structure allows automated optical inspection (AOI), enhancing solder joint reliability.
By continuing to expand its lineup, Toshiba aims to support the electrification and safety of automotive systems.
