SA56004X
Digital temperature sensor with overtemperature alarms
8.2 Power sequencing considerations
8.2.1 Power supply slew rate
When powering-up the SA56004X, ensure that the slew rate of V
DD
is less than 18 mV/ms.
A slew rate larger than this may cause power-on reset issues and yield unpredictable
results.
8.2.2 Application circuit
Figure 11
shows a typical application circuit for the SA56004X, using a discrete sensor
transistor connected via a shielded, twisted-pair cable. The pull-ups on SCLK, SDATA,
and ALERT
are required only if they are not already provided elsewhere in the system.
The SCLK and SDATA pins of the SA56004X can be interfaced directly to the SMBus of
an I/O controller, such as the Intel 820 chip set.
8.3 Timing and firmware consideration
It is important not to violate the conversion timing on this part.
Regardless of timing, the device could report an erroneous reading, but NXP, nor
reporting customers have not encountered two subsequent erroneous readings in its
product reviews or evaluations. Masking of single or two sequential erroneous readings is
recommended by comparing several reads should there be a large prompt change in the
temperature reading before taking protective action.
