ROHM BD1020HFV Technical data

Small and High Accuracy Temperature Sensor IC Series

Analog Output
Temperature Sensor IC

BD1020HFV

●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
