Microchip Technology, Inc. Temperature Sensors - Thermostats - Solid State MCP9510CT-E/CH

The MCP9510CT-E/CHCT-ND is a resistor-programmable temperature switch designed for applications requiring precise temperature control. It operates within a voltage range of 2.7V to 5.5V and features a low supply current of 30 µA (typical). The device offers temperature switch accuracy of ±0.5°C at +25°C, ±1°C from 0°C to +70°C, and up to ±4.5°C across a broader range of -20°C to +125°C. This temperature switch can be configured for either rising or falling temperature thresholds and supports multiple output configurations, including active-low push-pull and open-drain with an internal pull-up resistor. The user-selectable hysteresis options of 2°C or 10°C enhance design flexibility. The MCP9510 is housed in a compact SOT-23-6 package, making it suitable for space-constrained applications. Typical applications include power supply thermal shutdown, temperature alarms, thermostat control, fan control, and automotive systems. The device is capable of operating in ambient temperatures ranging from -40°C to +125°C, ensuring reliability in various environments.
