Example of board connection
Example of board connection

Description

  • Evaluation board of pre-driver IC (TC78B009FTG/TC78B027FTG) for 3 phase brush-less DC motor and external FET drive board.
  • FET drive board consists of PCB, 6 MOSFETs and right angle connector (board to board connector).
  • FET drive board is connected with the evaluation board of TC78B009FTG/TC78B027FTG by a right angle connector.

Features

  • The kind of MOSFET which can be mounted on the top side and the bottom side of the PCB is different, and it corresponds to two kinds of MOSFET packages (Top: TSON Advance, Bottom: UDFN6B). 
    (TSON Advance: TPN11003NL/TPN8R903NL etc., UDFN6B: SSM6K513NU/SSM6K504NU etc.)
  • Only by mounting 6 MOSFETs and right angle connector on the PCB, it is possible to connect to the evaluation board of TC78B009FTG/TC78B027FTG.

Description

TC78B009FTG

  • 3-phase brushless motor control pre-driver IC
  • Eliminating the Hall sensors allows reduction of mounting area and cost of IC, also contributing to motor downsizing and cost reduction.
  • Closed loop speed control allows stable rotational speed under load variations, without using external MCUs.
  • Various external FETs can be used since FET gate current can be configured using the internal non-volatile memory (NVM).

TC78B027FTG

  • 3-phase brushless motor control pre-driver IC
  • Intelligent Phase Control, a technology developed by Toshiba Electronic Devices & Storage Corporation ("Toshiba"), realizes an automatically optimized high-efficiency drive in a wide range of rotational speeds.
  • Closed loop speed control allows stable rotational speed under load variations, without using external MCUs.
  • Various external FETs can be used since FET gate current can be configured using the internal non-volatile memory (NVM).
