Overview
ADT7483A Dual Channel Temperature Sensor and Over Temperature Alarm 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.
The temperature of the remote thermal diode and ambient temperature 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.
The ADT7483A communicates over a 2-wire serial interface compatible with system management bus (SMBus) standards.
The SMBus address is set by the ADD0 and ADD1 pins.
As many as nine different SMBus addresses are possible.
An ALERT output signals when the on-chip or remote temperature is outside the programmed l...
