ADT7483A: Temperature Sensor, Over Temperature Alarm, Dual Channel
The ADT7483A is a three-channel digital thermometer and under/over temperature alarm, intended for use in PCs and thermal management systems. It can measure the temperature in two remote locations, for example, the remote thermal diode in a CPU or GPU, or a discrete diode connected transistor. It can also measure its own ambient temperature.
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
- Programmable Over/Under Temperature Limits
- Offset Registers for System Calibration
- Up to 2 Overtemperature Fail-safe overbar: THERM Outputs
- 240 µA Operating Current, 5 µA Standby Current
