TOKYO—Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TB67H450FNG,” the latest addition to its line-up of brushed DC motor driver ICs. The new product with a maximum rating of 50V/3.5A drives motors with a wide range of operating voltage. It also offers a small HSOP8 surface mount package with a popular pin-assignment that enhances the product sourcing possibility. Mass production starts today.
The new IC can drive brushed motors with a power supply ranging from 4.5V to 44V. It supports wide range of applications that includes, USB powered, battery powered, and industrial 12-36V devices. TB67H450FNG also has 3.5A current driving capability that can be used in applications such as robot vacuum cleaners, refrigerators and other home appliances actuators, office equipment, ATM machines, and many others.
To meet demand for lower power consumption, Toshiba has also optimized the TB67H450FNG standby current consumption with a new power supply circuit that allows the stop mode to move into standby mode automatically and to turn off the VCC regulator for internal circuit operation. This helps OA equipment and home appliances to cut energy consumption and improves the battery life of battery powered devices.
Housed in a small surface-mount type HSOP8 pin package, the IC achieves space saving and yet good heat dissipation through the package thermal pad design.
