Toshiba launches 5A 2-channel H-bridge motor-driven IC for car applications

China Shanghai, December 10, 2020 - Toshiba Electronics Components and Storage Devices Co., Ltd. ("Toshiba") today announced that two DC excavators for vehicles and other vehicles and other vehicles have driven IC - "TB9054FTG" And "TB9053FTG". Among them, "TB9054FTG" is encapsulated by a wet wet flap VQFN, and "TB9053FTG" is encapsulated by power type QFN. TB9054FTG has now available, which is expected to be increased in March 2022; TB9053FTG will be available from February 2021, which is expected to be mass production in May 2022. The amount of H-bridge motor driving of electronic throttle and various vehicle valves is increasing, which stimulates the need for system miniaturization and cost reduction. In addition, the second-generation car auto-in-Diagnostic equipment requirement (OBDII) will be implemented in 2022, requiring the automotive motor drive IC to have SPI communication. Today's new IC is driven by 5A [1] 2 channel output, which helps to reduce the placement area. Further, 10A [1] single channel drive can also be provided in parallel mode. Both drivers can be used in chrysanthemum chain, and also has functions that control the motor only via the SPI communication. Both methods help reduce MCU ports. A small QFN package with a size of 6.0mm × 6.0 mm size is aimed at meeting the system miniaturization needs of the market. Main characteristics: Ø Built-in 2-channel H-bridge drive output drive circuit consists of a low-conducting resistance DMOSFET, a 5A [1] 2 channel H-bridge drive is realized. 10A [1] single channel driver can also be provided in parallel mode. ØSPI communication daisy chain connection and only SPI communication can reduce the number of MCU ports, which is advantageous for implementing system miniaturization. Ø Small package TB9054FTG: small mount area with E-PAD 40-pin wet flap VQFN package TB9053FTG: small mount area with E-PAD 40-pin power type QFN package application: throttle, various engine valve , Foldable rearview mirrors and body systems, including in-vehicle applications such as electric door bolts. Main specifications: Note: [1] The actual motor drive current depends on the use environment and the ambient temperature, the supply voltage and other factors.
