| FM20 Ultra-Low-Power Analog Temperature Sensor • Analog Output, -11.77mV/°C • Range, -55 to 130°C • Accuracy, ±1°C at 25°C • Supply Current, 9µA typical • Output Drive, 1µA • Self-heating < 0.021°C • Operating Voltage +2.4V to +6V • Mobile Phones • Computers • Battery Management • Equipment • HVAC • Power Supply Modules • Disk Drives • Automotive Thermal Response VOUT mV As a precision CMOS temperature sensor, the FM20 is cost-effective for accurate low-power temperature monitoring applications. Output voltage versus temperature is extremely linear. With no load, the supply current is typically 1µA. For normal operation, the load on VOUT should be or less. In a typical application, a remotely mounted FM20 is monitored by a microcontroller with an analog A/D converter input. Alternatively, the FM20 can drive a comparator with a high impedance input. Accuracy is typically ±1°C at room temperature and better than ±2.5°C from 0 to 50°C. Available packages are surface mount 5-pin SC70 and 3-pin SOT-23. -50 -40 -25 Temperature VOUT 1863.9mV Temperature = FM20 Output Voltage vs. Temperature FM20 Pin Assignments VOUT GND N/C FM20 PRODUCT SPECIFICATION GND 3 FM20 1 VDD 2 VOUT Pin Descriptions Pin No. Pin Name SC-70 SOT-23 VOUT Type Analog Output VDD GND Power Function Temperature Sense.
