4 channels H-bridge motor driver IC, rating of 40 V/3.5 A

时间:2018-01-12 10:29来源:东芝半导体&存储产品


TB67H452FTG is an H-bridge motor driver IC with rating of 40 V and 3.5 A, and capable of driving up to four DC brushed motors. It can control 7.2 V motors with up to 3 A, allowing it to support lithium-ion battery-powered applications such as robot cleaners and assistant robots. Also, there is a trend to lower the driving voltage from 14.4 V to 7.2 V to reduce the battery cost. To match this trend, we developed the IC to support 7.2 V devices.

Other than robot equipment, demands of relatively low-power applications such as electric tools and surveillance cameras increase rapidly. TB67H452FTG started mass production as an optimal IC for these applications.

Three features
● TB67H452FTG can provide sufficient driving current though it supports the minimum of 6.3 V drive, satisfying the required operating range of the customer’s set.

● Simultaneous multiple motor drives are possible. : Up to four DC brushed motors, and up to two stepping motors in stepping motor mode.

● Assembling the driver into a small QFN package allows the customers to simplify the PCB patterns for heat dissipation. It is also affordable, space and cost-wise.
● Small home-use robots (cleaning robots, etc.)
● Electric tools
● Surveillance cameras
● Other battery-powered applications
