ADT7481中文资料Dual Channel Temperature Sensor and Over Temperature Alarm数据手册ONSEMI规格书

描述 Description

The ADT7481 is a 3-channel digital thermometer and under/over temperature alarm, intended for use in PCs and thermal management systems.It can measure its own ambient temperature or the temperature of two remote thermal diodes.These thermal diodes can be located in a CPU or GPU, or they can be discrete diode connected transistors.The ambient temperature, or the temperature of the remote thermal diiode, can be accurately measured to ±1°C.The temperature measurement range defaults to 0°C to +127°C, compatible with ADM1032, but can be switched to a wider measurement range from -64°C to +191°C.

特性 Features

• 1 Local and 2 Remote Temperature Sensors
• 0.25°C Resolution/1°C Accuracy on Remote Channels
• 1°C Resolution/1°C Accuracy on Local Channel
• Extended, Switchable Temperature Measurement Range 0°C to +127°C (default) or 64°C to +191°C
• 2-wire SMBus Serial Interface with SMBus Alert Support
