Toshiba Launches Low Power Consumption Brushed DC Motor Driver IC

Toshiba has launched its latest line-up of brushed DC motor driver ICs. The new product, TB67H450FNG, 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.

DC Motor Driver

The new IC can drive brushed motors with a power supply ranging from 4.5V to 44V. It supports a wide range of applications that includes USB powered, battery powered, and industrial 12-36V devices. The device 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 by newly developed power supply circuit, which allows the stop mode moving to the standby mode automatically and turns off VCC regulator for the internal circuit operation that 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.

The Key Features of the TB67H450FNG Brushed Driver ICs:

  • Wide range of operating voltages: from 4.5V to 44V for large-current drive devices
  • Low standby current consumption: 1 μA (max) @VM=24V, Ta=25°C
  • Small 8-pin surface mount package HSOP8 with a popular pin assignment and with bottom side E-pad to enhance thermal dissipation.

The Major Applications of the device includes:

  • Industrial equipment, including OA equipment and banking terminals
  • Home appliances, including robot vacuum cleaners
  • Battery powered devices (electronic locks and small household robots)
  • Devices using 5V USB power supplies

Mass Production has already started.
