Global Configuration Register (04h)
The global configuration register controls the shutdown
mode, power-on reset, SMBus timeout, and tempera-
ture channel 2 source select:
D7: Run/Standby. Normal operation is run (0).
Setting this bit to 1 suspends conversions and puts
the MAX6639 into low-power sleep mode.
D6: Software POR. Writing a 1 resets all registers to
their default values.
D5: SMBus Timeout Disable. Writing a zero
enables SMBus timeout for prevention of bus lockup.
When the timeout function is enabled, the SMBus
interface is reset if SDA or SCL remains low for more
than 74ms (typ).
D4: Temperature Channel 2 Source. Selects either
local or remote 2 as the source for temperature
channel 2 register data. Writing a zero to this bit
selects remote 2 for temperature channel 2.
D3: PWM Output Frequency Range. Selects either
the 20Hz to 100Hz range or the 5kHz to 25kHz range
for the PWM outputs (see Table 9).
Extended Temperature Registers (05h and 06h)
These registers contain the extended temperature data
from channels 1 and 2. Bits D[7:5] contain the 3 LSBs
of the temperature data. The bit values are 0.5
°C,
0.25
°C, and 0.125°C. When bit 0 is set to 1, a diode
fault has been detected.
Channel 1 and Channel 2
ALERT, OT, and THERM
Limits (08h Through 0Dh)
These registers contain the temperatures above which
the ALERT, THERM, and OT status bits set and outputs
assert (for the temperature channels that are not
masked). The data format is the same as that of the
channel 1 and channel 2 temperature registers: the
LSB weight is +1
°C and the MSB is +128°C.
