Toshiba Corporation's Storage & Electronic Devices Solutions Company today announced the launch of the TB67H452FTG, a 4-channel H-bridge motor driver IC offering a high voltage of 40V and current of 3.5A. The new IC is suited for small consumer products. Shipments start immediately.
In recent years, more and more products require high drive current with low power supply voltage, particularly small consumer products such as digital cameras, electric tools, notebook PCs, tablets and small domestic robots.
The new IC can supply an output current of up to 3.5A with low power supply voltage, suiting it for battery-powered applications, such as 7.2V power supply for small domestic robots, electric tools and surveillance cameras.
The new motor driver IC has both dc brushed motor drive and stepping motor drive interfaces, making possible combinations such as two dc brushed motor channels and one stepping motor channel. Customers have the freedom to select from a line-up that supports a wide range of devices.
Main features include: 1. Suited for applications that need high current with low power voltage. 2. Can drive up to four brushed motors simultaneously; in stepping motor mode, can simultaneously drive two stepping motors. 3. Packaging in a small QFN48-P-0707-0.50 package support customers in reducing heat problems and simplifying PCB design patterns to handle heat dissipation. Also realize an affordable solution in terms of space and cost.
4. Heat generation for a 2-channel simultaneous drive is reduced by low on resistance (0.6 Ω or less (upper + lower)). 5. A built-in sleep function by external pin control reduces IC current consumption at stand-by. 6. Incorporates thermal shutdown and over current detection circuits. The safety and reliability of equipment are increased by the error (ERR) signals they output during operation.
