Key Features
- Linear analog output of 10 mV/°C enables direct connection to ADC inputs without signal conditioning, simplifying system design for temperature monitoring from 0°C to 70°C
- 3-pin SOT-23 package (2.9 mm × 1.3 mm × 1.005 mm) enables ultra-compact PCB placement with surface-mount assembly and a 7-week standard factory lead time
- RoHS-compliant (JESD-609 e3) plastic housing with ±4°C maximum accuracy over the operating temperature range, suitable for non-precision thermal management and fan control applications
Applications
The MCP9700BT-E/TT is used in battery management systems, HVAC controllers, and consumer electronics where a simple analog voltage proportional to temperature eliminates the need for digital communication protocols. Its 10 mV/°C transfer function directly drives microcontroller ADC inputs at 3.3 V or 5 V supply rails without external resistor networks. The SOT-23-3 form factor allows placement close to heat-generating components for accurate local thermal monitoring.

Frequently Asked Questions
How does the MCP9700BT-E/TT output voltage relate to temperature for ADC interfacing?
The MCP9700BT-E/TT produces a linear analog output of 10 mV/°C, so at 25°C it outputs approximately 500 mV, rising to 700 mV at 45°C. This allows a 10-bit ADC on a 3.3 V rail to resolve temperature changes of about 0.3°C per LSB without any signal conditioning circuitry.
What accuracy limitations of MCP9700BT-E/TT should designers consider for thermostat applications?
The MCP9700BT-E/TT has a maximum accuracy of ±4°C, making it unsuitable for precision thermostat control requiring ±1°C or better. For HVAC zone sensing, battery over-temperature protection, or fan speed control where ±4°C is acceptable, the device provides adequate performance at lower cost than digital I2C temperature sensors.
How does the SOT-23-3 package size of MCP9700BT-E/TT benefit dense PCB layout near heat sources?
The MCP9700BT-E/TT SOT-23-3 package measures only 2.9 mm × 1.3 mm × 1.005 mm, allowing placement within 5 mm of heat-generating components such as MOSFETs or regulators without consuming significant board area, giving accurate local junction-area thermal readings for protection circuits.
