Output driver circuit is configured by DMOS FET with low on-resistance, realizing a 5A[1] 2ch H-bridge driver. A 10A[1] 1ch drive in parallel mode is also possible.
  • SPI communication
    Daisy-chain connectivity and motor control only by SPI communication both reduce MCU ports, contributing to system miniaturization.
  • Small packages
    TB9054FTG: Small surface mount wettable flank VQFN 40pin package with E-pad
    TB9053FTG: Small surface mount power QFN 40pin package with E-pad
  • Applications

     

    Automotive applications such as throttle valves, various engine valves, retractable door mirrors, and body systems, including electric door latches
