1 / 20 page  © Semiconductor Components Industries, LLC, 2009 December, 2009 − Rev. 6 1 Publication Order Number: ADT7461/D ADT7461 +15C Temperature Monitor with Series Resistance Cancellation The ADT7461 is a dual-channel digital thermometer and under/over temperature alarm intended for use in PCs and thermal management systems. It is pin- and register-compatible with the ADM1032. The ADT7461 has three additional features: series resistance cancellation (where up to 3 k W (typical) of resistance in series with the temperature monitoring diode may be automatically cancelled from the temperature result, allowing noise filtering); configurable ALERT output; and an extended, switchable temperature measurement range. The ADT7461 can accurately measure the temperature of a remote thermal diode to ±1°C and the ambient temperature to ±3°C. The temperature measurement range defaults to 0 °C to +127°C, compatible with the ADM1032, but can be switched to a wider measurement range of −55 °C to +150 °C. The ADT7461 communicates over a 2-wire serial interface compatible with system management bus (SMBus) standards. An ALERT output signals when the on-chip or remote temperature is out of range. The THERM output is a comparator output that allows on/off control of a cooling fan. The ALERT output can be reconfigured as a second THERM output, if required. The SMBus address of the ADT7461 is 0x4C. An ADT7461-2 is also available, which uses SMBus Address 0x4D.
