The AS273 is a series of programmable over-temperature detectors. Each is internally composed of a precision 2.5 V shunt reference, a proportional-to-absolute temperature thermal sensor, a comparator with controlled hysteresis, and an open collector output that indicates an over-temp condition. The threshold for the over-temp signal can be set to any of three values on a given part by controlling the magnitude of the reference shunt current.
1. Programmable to three different over-temperature thresholds 2. 2.5 V temperature compensated bandgap reference trimmed to 1% 3. Open collector output goes low on over-temp condition

RH5VT21CC Series are voltage detector ICs with high threshold accuracy and ultra-low supply current by CMOS process, which can be operated at an extremely low voltage and is used, for instance, for system reset. Each of these ICs consists of a voltage reference unit, a comparator, resistors for voltage detection, an output driver and a hysteresis circuit. The detector threshold is fixed with high accuracy.
1. Ultra-low Supply Current : TYP. 0.8μA (VDD=1.5V) 2. Broad Operating Voltage Range : 0.7V to 10.0V (Topt =25°C) 3. Detector Threshold : Stepwise setting with a step of 0.1V in the range of 0.9V to 6.0V is possible (refer to Selection Guide).
4. High Accuracy Detector Threshold : ±2.5% 5. Low Temperature-Drift Coefficien of Detector Threshold : TYP. ±100ppm/°C 6. Two Output Types : Nch Open Drain and CMOS
