Analog Output
Temperature Sensor IC
BD1020HFV
No.10047EBT02
●Description
Low quiescent current (4µA) and high accuracy temperature sensor
Detecting temperature by itself, output voltage appears linearly along the temperature.
●Features
1) Detection Temperature Range -30～+100℃
2) Operating Voltage Range
+2.4V～+5.5V
3) High Accuracy ( typically ±1.0℃@Ta=30℃, typically ±2.0℃@Ta=-30～+100℃ )
4) Temperature Sensitivity ( typically -8.2mV/℃ )
5) Low Quiescent Current ( typically 4µA )
6) Ultra Small Package ( typically 1.60mm×1.60mm×0.60mm)
7) Low Thermal Resistance ( typically 187℃/W )
8) ESD Rating 8kV ( HBM )
9) Excellent Ripple Rejection Characteristic
●Applications
Cell Phone ( RF Module, Battery Thermal Management ),Audio Systems,Digital Still Camera
LCD, PDP,Optical pick up module for DVD,BlueRay
●Absolute Maximum Ratings ( Ta=25℃ )
