Toshiba Introduces World's Lowest Power Consumption Voltage
Regulator IC for Automotive Applications
Tokyo, Japan, Sept. 24, 2002 - (JCN Newswire) - Toshiba Corporation
today announced a voltage regulator IC for automotive application that
achieves the world's lowest power consumption in this class of device.
The new IC, TB9001FN, has a power consumption of 95 microamperes (A),
approximately 20% lower than the most efficient of Toshiba's current
voltage regulator IC. It achieves this by employing *BiCD process
technology and optimized internal circuits.
The IC can also integrate a 32KHz sub-clock circuit that replaces such
external components as the shock-sensitive crystals and ceramics that
are now used to activate some systems including anti-theft systems when
vehicle's engine is switched off and the micro-controller LSI is in
sleeping mode. These features offer longer battery life, as well as
stable output voltage, in a wide range of operating temperatures.
Samples are available today at a unit price of 300 yen. Mass production
is slated for the second quarter of 2003 at a monthly volume of 1
million units.
Recent advances in automotive electronics have brought more and more
micro-controller LSIs into vehicles, including those to control
anti-theft system, auto-lock system and car area network system. These
advanced features consume more current, even when the engine is switched
off, placing more demands on the vehicle battery.
Toshiba's new voltage regulator IC supports the automobile industry in
finding a solution to this problem. With a power consumption of only
95A, the world's lowest for this kind of device, and integration of the
sub-clock circuit, the new IC contributes to support a longer battery
life and highly reliable system.
*BiCD: Integration of Bipolar transistors, CMOS FET and high-voltage and
huge-electric-current DMOS.
