General Description
The G751 is a temperature sensor, Delta-Sigma
analog-to-digital converter, and digital over- tem-
perature detector with SMBus
interface. The host
can query the G751 at any time to read temperature.
The open-drain Over temperature Shutdown (O.S.)
output becomes active when the temperature ex-
ceeds a programmable limit. This pin can operate in
either "Comparator" or "Interrupt" mode.
The host can program both the temperature alarm
threshold (T
OS
) and the temperature at which the
alarm condition goes away (T
HYST
). In addition, the
host can read back the contents of the G751's T
OS
and T
HYST
registers. The sensor powers up in Com-
parator mode with default thresholds of 50C T

45C T

Temperature-to-Digital Transfer Function (Non-linear scale for clarity)
Functional Description
The G751 temperature sensor incorporates a
band-gap type temperature sensor and 9-bit ADC
(Delta-Sigma Analog- to-Digital Converter). The
temperature data output of the G751 is available at
all times via the SMBus. If a conversion is in pro-
gress, it will be stopped and restarted after the read.
A digital comparator is also incorporated that com-
pares a series of readings, the number of which is
user-selectable, to user-programmable setpoint and
hysteresis values. The comparator trips the O.S.
output line, which is programmable for mode and
polarity.
O.S. Output, T
OS
and T
HYST
Limits
In Comparator mode the O.S. Output behaves like a
thermostat. The output becomes active when tem-
perature exceeds the T
OS
limit, and leaves the active
state when the temperature drops below the T
HYST
limit. In this mode the O.S. output can be used to
turn a cooling fan on, initiate an emergency system
shutdown, or reduce system clock speed. Shutdown
mode does not reset O.S. state in a comparator
mode.
In interrupt mode exceeding T
OS
also makes O.S.
active but O.S. will remain active indefinitely until
reset by reading any register via the SMBus inter-
face. Once O.S. has been activated by crossing T
OS
,
then reset, it can activated again only by Tempera-
ture going below T
HYST
. Again, it will remain active
indefinitely until being reset by a read. Placing the
G751 in shutdown mode also resets the O.S. output.
Default Modes
G751 always powers up in a known state. G751
power up default conditions are:
1. Comparator mode
2. T
OS
set to 50C for G751-1, to 80C for G751-2
3. T
HYST
set to 45C for G751-1, to 75C for G751-2
4. O.S. active low
5. Pointer set to "00"; Temperature Register
With these operating conditions G751 can act as a
stand-alone thermostat with the above temperature
settings. Connection to an SMBus is not required.
SMBus Interface
The G751 operates as a slave on the SMBus, so the
SMBCLK line is an input (no clock is generated by
the G751) and the SMBDATA line is a bi-directional
serial data path. According to SMBus specifications,
the G751 has a 7-bit slave address. The four most
significant bits of the slave address are hard wired
inside the G751 and are "1001". The three least sig-
nificant bits of the address are assigned to pins
A2-A0, and are set by connecting these pins to
ground for a low, (0); or to +Vs for a high, (1).
Therefore, the complete slave address is:
1 0 0 1 A2

Shutdown Mode
Shutdown mode is enabled by setting the shutdown
bit in the Configuration register via the SMBus. Shut-
down mode reduces power supply current to 1 A
typical. In interrupt mode O.S. is reset if previously
set and is undefined in Compatator mode during
shutdown. The SMBus interface remains active. Ac-
tivity on the clock and data lines of the SMBus may
slightly increase shutdown mode quiescent current.
T
OS
, T
HYST
, and Configuration registers can be read
from and written to in shutdown mode.
Fault Queue
A fault queue of up to 6 faults is provided to prevent
false tripping of O.S. when the G751 is used in noisy
environments. The number of faults set in the queue
must occur consecutively to set the O.S. output.
Comparator/Interrupt Mode
As indicated in the O.S. Output Temperature Re-
sponse Diagram, Figure 1, the events that trigger
O.S. are identical for either Comparator or Interrupt
mode. The most important difference is that in Inter-
rupt mode the O.S. will remain set indefinitely once it
has been set. To reset O.S. while in Interrupt mode,
perform a read from any register in the G751.
O.S. Output
The O.S. output is an open-drain output and does
not have an internal pull-up. A "high" level will not be
observed on this pin until pull-up current is provided
from some external source, typically a pull-up resis-
tor. Choice of resistor value depends on many sys-
tem factors but, in general, the pull-up resistor
should be as large as possible. This will minimize
any errors due to internal heating of the G751. The
maximum resistance of the pull up, based on G751
specification for High Level Output Current, to pro-
vide a 2V high level, is 30k
.
O.S. Polarity
The O.S. output can be programmed via the con-
figuration register to be either active low (default
mode), or active high. In active low mode the O.S.
output goes low when triggered exactly as shown on
the O.S. Output Temperature Response Diagram,
Figure 1. Active high simply inverts the polarity of the
O.S. output.

G751
Global Mixed-mode Technology Inc.
Internal Register Structure
There are four data registers in the G751, selected
by the Pointer register. At power-up the Pointer is set
to "00"; the location for the Temperature Register.
The Pointer register latches whatever the last loca-
tion it was set to. In Interrupt Mode, a read from the
G751, or placing the device in shutdown mode, re-
sets the O.S. output. All registers are read and write,
except the Temperature register which is read only.
A write to the G751 will always include the address
byte and the Pointer byte. A write to the Configura-
tion register requires one data byte, and the T
OS
and
T
HYST
registers require two data bytes.
Reading the G751 can take place either of two ways:
If the location latched in the Pointer is correct (most
of the time it is expected that the Pointer will point to
Temperature register because it will be the data
most frequently read from the G751), then the read
can simply consist of an address byte, followed by
retrieving the corresponding number of data bytes. If
the Pointer needs to be set, than an address byte,
pointer byte, repeat start, and another address byte
will accomplish a read.
The first data byte is the most significant byte with
most signification bit first, permitting only as much
data as necessary to be read to determine tempera-
ture condition. For instance, if the first four bits of the
temperature data indicates an overtemperature con-
dition, the host processor could immediately take
action to remedy the excessive temperatures. At the
end of a read, the G751 can accept either Acknowl-
edge or No Acknowledge from the Master (No Ac-
knowledge is typically used as a signal for the salve
that the Master has read its last byte).
An inadvertent 8-bit read from a 16-bit register, with
the D7 bit low, can cause the G751 to stop in a state
where the SDA line is held low as shown in Figure 2.
This can prevent any further bus communication until
at least 9 additional clock cycles have occurred. Al-
ternatively, the master can issue clock cycles until
SDA goes high, at which time issuing a "Stop" condi-
tion will reset the G751.
