TelCom Semiconductor Announces Ultra-Small and Low Power CMOS Voltage Detector with Output Delay at a Low Installed Cost.MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--April 30, 1999-- TelCom Semiconductor, Inc. (Nasdaq: TLCM TLCM Through-Life Capability Management TLCM Tivoli Licensing Compliance Manager (IBM) TLCM Tivoli License Compliance Manager TLCM Top Load Configurable Monopole (antenna) ) today announced the TC51, a very low power CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. voltage detector with built-in delay. It is particularly well suited for battery powered applications because of its low power consumption and small SOT-23A-3 surface-mount packaging. The TC51 offers a significantly lower operating current than its closest competitor at 1uA and a precise detection threshold of +/- 2%. The TelCom TC51 provides design flexibility by allowing the user to choose the reset single threshold setting that is best suited for their system power supply voltage. Each part is laser-trimmed to the desired threshold voltage The threshold voltage of a MOSFET is usually defined as the gate voltage where a depletion region forms in the substrate (body) of the transistor. In an NMOS the substrate of the transistor is composed of p-type silicon which has more positively charged electron holes compared to , which can be specified from 1.6V to 6.0V in 0.1V steps. The standard built-in output delay for this device is 50msec - 200msec. The device includes a comparator comparator Instrument for comparing something with a similar thing or with a standard measure, in particular to measure small displacements in mechanical devices. In astronomy, the blink comparator is used to examine photographic plates for signs of moving bodies. , a low-current high-precision reference, a laser-programmed voltage divider voltage divider: see potentiometer. , a hysteresis hysteresis (hĭs'tərē`sĭs), phenomenon in which the response of a physical system to an external influence depends not only on the present magnitude of that influence but also on the previous history of the system. circuit, and an output driver with digital delay timer. The TC51 continuously monitors its input supply for an out-of-tolerance condition. When such a condition is detected, the output immediately is driven and held low. The output returns to its high state after the input supply is within tolerance (200msec, max). The TC51 is ideal for processor reset monitors in battery operated systems such as pagers, PDAs (personal digital assistants), and cellular phones. One thousand piece pricing for the TC51 starts at $0.72. The data sheet can be accessed at the company's web site at: http://www.telcom-semi.com/datashts/TC51.pdf.
