Over-Limit-Signal Temperature Register (T
OS
)
The T
OS
Register is a two-byte (16-bit) read/write register
that stores the user-programmable upper trip-point
temperature for the thermal alarm in two’s-complement
format. At power-up this register defaults to 80°C
(i.e., 0101 0000 0000 0000).
The format of the TOS register is identical to that of the
Temperature Register (see Figure 6). The 4 LSBs of the T
OS
Register are hardwired to zero, so data written to these
register bits will be ignored. The MSB position of the T
OS
Register contains the sign bit for the digital temperature and
bit 14 contains the temperature MSB.
The resolution setting for the T-to-D conversion determines
how many bits of the T
OS
Register are used by the thermal
alarm. For example, for 9-bit conversions the trip-point
temperature is defined by the 9 MSBs of the T
OS
register,
and all remaining bits are “don’t cares.”
Hysteresis Temperature Register (T
HYST
)
The T
HYST
Register is a two-byte (16-bit) read/write
register that stores the user programmable lower trip-point
temperature for the thermal alarm in two’s-complement
format. At power-up this register defaults to 75°C (i.e., 0100
1011 0000 0000).
The T
HYST
register is illustrated in Figure 6. The format of
this register is the same as that of the Temperature Register.
The 4 LSBs of the T
HYST
register are hardwired to zero, so
data written to these bits is ignored.
The resolution setting for the T-to-D conversion determines
how many bits of the T
HYST
Register are used by the thermal
alarm. For example, for 9-bit conversions the hysteresis
temperature is defined by the 9 MSBs of the T
HYST
Register,
and all remaining bits are “don’t cares.”
