Small and high accuracy Temperature Sensor IC Series High Accuracy detection
Thermostat Output
Temperature Sensor ICs
with Power Down Function
BDJ□□□1HFV Series
No.09047ECT01
●Description
BDJ□□□1HFV series is thermostat output temperature sensor IC with built-in temperature detection element,constant
current circuit,high-accuracy reference voltage source in one chip.Temperature detection can be realized at ±2.5℃
accuracy without complicated design.It is the best temperature sensor IC for a portable equipment of micro and low
current,the power down function, and the battery drive.It is possible to use it for a wide usage such as the heat detection
and temperature monitors because it provides with the analog output in addition to the thermostat power output.
BDJ□□□1HFV series has 8 types of model at 5℃ intervals from +55℃ to +90℃ temperature range.
●Features
1) Detection Temperature Range 55~90℃ by 5℃ Step 8 products.
2) Power supply Voltage range 2.4~5.5V.
3) High Accuracy thermostat ( typ.±1.0℃, max.±2.5℃ @Ta=55~90℃ )
4) High Accuracy Analog Output ( typ.±1.0℃, max.±2.5℃ @Ta=-30~100℃ )
5) Analog Output Temperature Sensitivity ( typ. -8.2mV/℃ )
6) Low Supply Current ( typ. 7.5μA )
7) Power down control function built in.(PD interface Voltage min 1.5V)
8) Small Package ( typ. 1.60mm×1.60mm×0.60mm )
9) Low thermal resistance package ( typ. 187℃/W )
10) ESD Rating 8kV ( HBM )
●Applications
Cell phone, Digital Camera,Thermal Protection for Electrical Equipment (NoteBook PC, FPD-TV, etc.)
●Line up matrix
