The Philips SA56004X is an SMBus compatible, 11-bit remote/localdigital
temperature sensor with over temperature alarms. The remote channel of
the SA56004 monitors a diode junction, such as a substrate PNP of a
microprocessor or a diode connected transistor such as the 2N3904 (NPN)
or 2N3906 (PNP). With factory trimming, remote sensor accuracy of 1C
is achieved.

Under and over temperature alert thresholds can be programmed to cause
the ALERT output to indicate when the on-chip or remote temperature is
out of range. This output may be used as a system interrupt or SMBus
alert. The T_CRIT output is activated when the on-chip or remote
temperature measurement rises above the programmed T_CRIT threshold
register value. This output may be used to activate a cooling fan, send
a warning or trigger a system shutdown. To further enhance system
reliability, the SA56004X employs an SMBus time-out protocol. The
SA56004X has a unique device architecture which is patented (U.S.
patent #6542020).

The SA56004X is available in the SO8 and TSSOP8 packages.SA56004X has 8
factory-programmed, device address options.The SA56004X is
pin-compatible with the LM86, MAX6657/8, and ADM1032.
