Microchip Technology Inc. has announced a family of ten voltage supervisors: the MCP1316, MCP1316M, MCP1317, MCP1318, MCP1318M, MCP1319, MCP1319M, MCP1320, MCP1321 and MCP1322. These voltage supervisors offer a watchdog timer, manual reset, multiple combinations of push-pull or open-drain reset outputs, and factory trip-points from 2V to 4.7V in 100mV increments, all in a small, 5-pin SOT-23 package.

The voltage supervisors monitor microprocessor activity in digital systems. They operate at input voltages as low as 1V up to 5.5V, consume 5µA (typical), and offer a wide range of trip points between 2V and 4.7V. All of these features in their small package enable the MCP13XX voltage supervisors to increase design efficiency and flexibility, as well as reduce overall system costs, said Microchip.

"The MCP1316-MCP1322 voltage supervisors incorporate several attractive features on a single chip, resulting in enhanced design flexibility, reduced board space and lower system costs," said John Austin, senior product marketing engineer with Microchip's analogue and interface products division. "These devices are among only a few on the market guaranteed to operate within the extended industrial temperature range, making them excellent solutions for automotive, industrial and many other applications."

In addition to automotive and industrial applications, the voltage supervisors are appropriate for portable and handheld computing devices, plasma screen TVs, and DVD players.

The MCP1316, MCP1316M, MCP1317, MCP1318, MCP1318M, MCP1319, MCP1319M, MCP1320, MCP1321 and MCP1322 voltage supervisors are already available for sampling. Rated for operation within the extended industrial temperature range of -40°C to 125°C, the products are offered in 5-pin SOT-23 packages (2.95-by-2.8mm) and are all priced at Rs.18.94 (42 cents) each in 10,000-unit quantities.
