Description
The ADT7482 1 is a three-channel digital thermometer and undertemperature/overtemperature alarm for PCs and thermal management systems.
It can measure the temperature in two remote locations, such as in the remote thermal diode in a CPU or GPU, or using a discrete diode connected transistor.
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 Automatically cancels up to 1.5 kΩ (typ) of resistance in series with the remote sensors Extended, switchable temperature measurement range 0°C to +127°C (default) or.
- 55°C to +150°C 2-wire SMBus serial interface with SMBus alert support Programmable overtemperature/undertemperature limits Offset registers for system calibration Up to 2 overtemperature f.
