DS21498B-page 1 TC1047/TC1047A Features • Supply Voltage Range: - TC1047: 2.7V to 4.4V - TC1047A: 2.5V to 5.5V • Wide Temperature Measurement Range: -40oCto+125oC • High Temperature Converter Accuracy: ±2oC, Max, at 25°C • Linear Temperature Slope 10mV/°C (typ.) • Available in 3-Pin SOT-23B Package • Very Low Supply Current: -35 µATypical Applications • Cellular Phones • Power Supply Thermal Shutdown • Temperature Controlled Fans • Temperature Measurement/Instrumentation • Temperature Regulators • Consumer Electronics • Portable Battery Powered Equipment Device Selection Table Package Type General Description The TC1047 and TC1047A are linear voltage output temperature sensors whose output voltage is directly proportional to the measured temperature. The TC1047 and TC1047A can accurately measure temperature from -40°C to +125°C. With the TC1047, the supply voltage can vary between 2.7V and 4.4V. The power supply range of the TC1047A is from 2.5V to 5.5V. The output voltage range for these devices is typically 100mV at -40°C, 500mV at 0°C, 750mV at +25°C, and 1.75V at +125°C. A 10mV/°C voltage slope output response allows for a predictable temperature measurement over a wide temperature range. The TC1047 and TC1047A are packaged in 3-Pin SOT-23B packages, making them ideal for space critical applications. Block Diagram Part Number Package Temp.
