TOKYO -- August 8, 2013

Toshiba Corporation (TOKYO:6502) today announced the launch of “TB67H400A”, a
2-channel motor driver IC for brush motors that supports high voltages and
currents. Sample shipments starts today and mass production is scheduled to
start in October this year.

The latest high voltage analog process used for “TB67H400A”, realizes a 50V
maximum rating and low on resistance^[1] of 0.5Ω (maximum, sum of the upper
and lower side) during motor drive output, supporting maximum output current
of 4.0A per channel for a 2-channel drive. Toshiba’s original parallel channel
control function (large mode) offers 8.0A maximum output current when
2-channel parallel outputs are used as a 1-channel driver.

The driver IC is available in a 4 package line-up that supports various
customer requirements, such as equipment downsizing with a small package, and
continuous operation at high current with a high-power dissipation package.

Key Features of the New Products
1. High current drive
Reduction of maximum on resistance to 0.5Ω (sum of the upper and lower side)
realizes 4.0A per channel as maximum output current (4.0A x 2 channels). Large
mode supports 8.0A maximum output current (8.0A x 1 channel).

2. Package line-ups
Heat dissipating ZIP package improves allowable power dissipation, supporting
applications that require continuous motor drive at high current.
Small QFN and HTSSOP package contributes to downsizing of equipment and
reduction of material costs.
HSOP package enables flow soldering on a paper phenolic board whose demand is
increasing for the reduction of PCB cost.

3. Integrated abnormality detection functions
The ICs integrate a thermal shutdown circuit, overcurrent shutdown circuit,
and undervoltage lockout circuit, contributing to highly reliable
applications.

Applications
Home appliances such as sewing machines, ATMs, banknote recognition equipment,
amusement machines and office automation equipment

Note
[1] Resistance in applying current. When resistance is low, power loss is
small in motor driving and heat generation is reduced.
