Range of Package Sizes and Reliability Features Make Device Ideal Choice for a Wide Variety of Applications
Toshiba America Electronic
Components, Inc. (TAEC)*, a committed leader that collaborates with
technology companies to create breakthrough designs, today announced the
newest addition to the company's motor driver family, the TB67H400A. The
new device is a 2-channel motor
driver IC supporting the high voltage and current requirements of
brushed DC motors in industrial and office automation (OA) equipment
under continuous operation. Package and reliability features of the
TB67H400A improve operation for a variety of applications such as home
appliances, ATMs, banknote recognition equipment, amusement park
machines and office automation equipment.
"Continuous operation requires industrial and OA equipment that have
reliable thermal management or there will be system failure," says
Andrew Burt, vice president of the Analog and Imaging Business Unit,
System LSI Group at TAEC. "In addition, these systems need to be quiet,
low energy and as efficient as possible . Toshiba is creating a large
portfolio of motor control drivers that satisfy these requirements for
many different classes of motors in industrial and OA equipment ."
TAEC leveraged its latest high-voltage analog process in the design of
the TB67H400A. The device realizes a 50V maximum rating and low-on
resistance of 0.5 Ω (maximum, sum of the upper and lower side MOSFETs)
during motor drive output, thereby creating a maximum operating current
of 3.0 A(4.0A rated), per channel, for a 2-channel drive. Toshiba's
unique parallel channel control function (high-current mode) delivers a
6 .0A maximum operating current (8.0A rated) when 2-channel outputs are
used as a 1-channel driver.
The driver IC is available in a four package line-up to address various
customer requirements. A thermally efficient ZIP package improves power
dissipation for applications that need a continuous motor drive at high
current. Small QFN and HTSSOP packages enable downsizing of equipment
and reduction of material costs. An HSOP package allows flow soldering
on a paper phenolic board which helps reduce cost of printed circuit
board development.
The TB67H400A integrates abnormality detection functions for high
reliability. The IC includes a thermal shutdown circuit, over-current
shutdown circuit, and under-voltage lockout circuit.
Pricing and Availability
Sample pricing for the TB67H400A is $ 2.40 (U.S.). Sample shipments
begin today with mass production scheduled for October, 2013.
