Microchip Technology Introduces Resistor-Programmable Logic-Output Temperature Switches
Designers Can Stock One Device for Measuring Multiple Temperature Points
CHANDLER, Ariz., Dec. 8, 2008 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced the MCP9509 and MCP9510 (MCP9509/10) resistor-programmable, logic-output temperature switches. The low-power devices' temperature-switch threshold can be programmed with a single external resistor, meaning designers can stock one device for measuring multiple temperature points by varying the external resistance value. With an operating voltage range of 2.7 - 5.5V and the ability to trigger for temperatures ranging from -40 to 125°C with high accuracy, the MCP9509/10 switches enable better, smaller and less expensive designs.
Many applications require monitoring multiple temperature points within the system. The MCP9509/10 switches monitor temperature based upon user-programmed resistance values. When the programmed temperature threshold is reached, the switches alert the system and the system can react accordingly. User-programmable features, such as 2°C and 10°C (typical) switch hysteresis and output-structure configuration, mean the switches simplify designs and provide more flexibility to the designer. The MCP9509 has a low static operating current of just 30 micro Amperes and provides an open-drain output; while the MCP9510 has a static operating current of only 50 micro Amperes and is offered in three different user-selectable output configurations-active-low push pull, active-high push pull, and active-low open-drain output with an internal 100 kilo Ohm pull-up resistor.
"We are pleased to help designers simplify and customize their designs with this new series of resistor-programmable temperature switches," said Bryan Liddiard, vice president of marketing for Microchip's Analog & Interface Products Division. "These switches provide the functionality needed to accurately measure multiple temperature points in a system, while minimizing design size and cost."
"The MCP9509 and MCP9510 temperature switches complement market trends toward smaller, better, lower-power and less-expensive end products," said John Austin, senior product marketing manager for Microchip's Analog & Interface Products Division. "The devices represent a significant expansion of Microchip's thermal-management product family."
The MCP9509/10 switches are well-suited for battery-powered applications in the industrial (power supplies, wireless handsets and meters, multimeters); automotive (engine-temperature monitoring); medical (pharmaceutical storage-environment temperature control, refrigeration control); appliance (refrigerators and freezers) and consumer markets (PCs and peripherals).
Packaging, Pricing & Availability
The MCP9509 temperature switches are available in a 5-pin SOT-23 package; the MCP9510 in a 6-pin SOT-23 package. Both devices are priced at $0.61 each, in 10,000-unit quantities.
