TELCOM DEBUTS LOW-POWER CIRCUITS FOR BATTERY-POWERED APPLICATIONS.

TelCom Semiconductor, Inc. (NASDAQ: TLCM), Mountain View, Calif., has introduced the TC1270 and TC1271, 4-Pin low-power microprocessor supervisory circuits that monitor power supplies in digital systems and provide a reset signal to the host when necessary.

These devices require no external components and their small-size, low installed cost and low supply current make them the ideal choice for battery powered applications.

The TC1270/71 feature low 7uA supply current and 140msec guaranteed minimum /RESET output duration. The TC1270 has an active-low RESET output, while the TC1271 has an active-high /RESET output. These products are optimized to reject fast transient glitches on the Vcc line.

"The TC1270 and TC1271 are ideal for use in applications such as intelligent instruments, computers and microcontrollers. In addition to the industry standard threshold voltages, TelCom also offers a 1.75V option for lower voltage systems," said Pat Maresca, Product Marketing Manager at TelCom Semiconductor.

With their low supply current, the TC1270/1 are ideal for computers, embedded systems, battery-powered applications, and critical uP power supply monitoring. Both devices are available in the space-saving 4-Pin SOT-143 package, and are second-source replacements for Maxim's MAX811 and MAX812. The TC1270/71 are available through distribution and one thousand piece pricing starts at $0.78.
