Small and High Accuracy Temperature Sensor IC Series
Detect TemperatureChangeable
Thermostat Output Temperature Sensor IC
BDE□□□0G Series
No.09047EAT03
●Description
Low quiescent current (16µA), high accuracy thermostat (temperature switch) ICs. Built in temperature sensor, reference
voltage regulator, D/A converter, and comparator. Detecting temperature by itself, OS terminal state is changed at logically.
Open Drain Output ( Active L ) is available in BDE□□□0G series.
●Features
1) Detection Temperature Range -25½+125℃ by 15 products.
2) ±5℃ Step Selectable Detection Temperature with CTRL.
3) Hysteresis Temperature ( typically 10℃ )
4) High Accuracy Analog Output ( typically ±3.5℃@Ta=30℃ )
5) Analog Output Temperature Sensitivity ( typically -10.8mV/℃ )
6) Low Supply Current ( typically 16µA )
7) Small Package ( typically 2.90mm×2.80mm×1.25mm )
8) ESD Rating 8kV ( HBM )
9) Excellent Ripple Rejection Characteristic
●Applications
Thermal Protection for Electrical Equipment (NoteBook PC, Cell phone, FPD-TV, etc.) FAN Control for Thermal Management
