| austriamicrosystems Introduces AS1904/5/6 Family of Ultra Low Power Supervisory Circuits Ideal for Portable Applications |
 Ideal for Portable/Battery-Powered Equipment, Computers, Intelligent Instruments, Critical µP and µC Power Monitoring, Controllers and Automotive Applications RALEIGH , N.C. – September 17, 2004 – austriamicrosystems has launched the AS1904/5/6 family of ultra low power supervisory circuits. With a current consumption of only 150nanoAmperes (typical), the devices are i deal for portable/battery-powered equipment, com-puters, controllers, critical µP and µC power monitori ng, intelligent instruments and automotive applications. The AS1904/5/6 family delivers the world' s lowest power consumpti on and reduces costs by eliminating all external components. Highly reliable, the AS1904/5/6 family devices monitor the supply voltage of digital systems and microprocessors and initiate a reset if the voltage decreases below a certain threshold. The state of the reset is active for a predefined time after the supply voltage has risen above the threshold. The product family offers three devices with different output drivers. The AS1904 has a push-pull driver with an active low reset. The AS1905 uses the same output stage, but has an active high reset. The AS1906 has an open drain output with an active low reset. Each device is of-fered with four typical time out periods: 5ms, 20ms, 100ms and 500ms (factory trimmed). "The outstanding low current consumption of only 150nA (typ) at 3.3V makes the AS1904/5/6 family ideal for use in portabl e applications" said Walter Moshammer, Marketing Director of austriamicrosystems’ communications business unit. "All devices of the AS1904/5/6 family operate down to a voltage of 1V. A hysteresis in the threshold guarantees that fast transients and noise on the supply line do not lead to unwanted resets. Furthermore the reset threshold is factory trimmable between 2.2V and 3.1V with 1.5% tolerance. The circuit is designed to be especialy robust against RF-interference". The AS1904/5/6 fami ly of devices is available immediately in a 3-pi n SOT23 packaging, priced below $1.00 starting at 1,000 units.
