STTS751 register summary
STTS751
Doc ID 16483 Rev 4
4.9
Therm limit
The Therm limit is a read/write register located at address 20h. The power-on default value
is 85 °C (55h). The format is 8-bit, two's complement integer. This is the same format as
the upper byte of the temperature register (Section 4.2: Temperature register format).
Whenever the temperature exceeds the value of the therm limit, the Addr/Therm output will
be asserted (low). See Section 6 for more information.
4.10
Therm hysteresis
The Therm hysteresis values controls the hysteresis for Addr/Therm output. Once Therm
output has asserted, it will not de-assert until the temperature has fallen below the
respective therm limit minus the therm hysteresis value. See Section 5 for more
information.
The therm hysteresis register is read/write and is located at address 21h. The power-up
default value is 10 °C (0Ah). The format is 8-bit, two's complement integer.
4.11
SMBus timeout register
At power-up, the STTS751 is configured with an SMBus timeout of 25 to 35 milliseconds
TIMEOUT: [bit 7]
1: SMBus timeout is enabled. Default condition.
0: SMBus timeout is disabled.
[bits 6:0] Not used - reserved.
