ADT6501/ADT6502/ADT6503/ADT6504 低成本2.7V至5.5 V,微温度控制开关 采用SOT-23封装
ADT6504： low cost ,2.7 V to 5.5 V, Micro power temperature switch at SOT-23(monitor temperature from −45°C to 15)
Product DescripTIonThe ADT6501/ADT6502/ADT6503/ADT6504 are trip point temperature switches available in a 5-lead SOT-23 package. Each part contains an internal band gap temperature sensor for local temperature sensing. When the temperature crosses the trip point setTIng, the logic output is acTIvated. The ADT6501/ ADT6503 logic output is acTIve low and open-drain. The ADT6502/ADT6504 logic output is active high and push-pull. The temperature is digitized to a resolution of 0.125°C (11-bit). The factory trip point settings are 10°C apart starting from −45°C to +15°C for the cold threshold models and from +35°C to +115°C for the hot threshold models.
The device does not require external components, typically consumes 30μA supply current. Hysteresis is pin-selectable at 2 ℃ and 10 ℃. Temperature switch is assigned to the operating voltage range of 2.7V to 5.5 V.
The ADT6501 and ADT6502 to monitor temperature from + 35 ℃ deg.] C to + 115 ° only. Thus, when the higher the temperature is below the selected transition point temperature, logic output pin becomes active.
ADT6503 and ADT6504 are only used to monitor temperature °C #8722;45 to 15. therefore, the logic output pin becomes active when the temperature is below the selected trip point temperature.
