Detailed Description
The MAX6602 is a precision multichannel temperature
monitor that features one local and four remote temper-
ature-sensing channels with a programmable alert
threshold for each temperature channel and a program-
mable overtemperature threshold for channels 1 and 4
(see Figure 1). Communication with the MAX6602 is
achieved through the SMBus serial interface and a
dedicated alert output. The alarm outputs, OVERT and
ALERT, assert if the software-programmed temperature
thresholds are exceeded. ALERT typically serves as an
interrupt, while OVERT can be connected to a fan, sys-
tem shutdown, or other thermal-management circuitry.
ADC Conversion Sequence
In the default conversion mode, the MAX6602 starts the
conversion sequence by measuring the temperature on
channel 1, followed by 2, 3, local channel, and 4. The
conversion result for each active channel is stored in
the corresponding temperature data register.
In some systems, one of the remote thermal diodes may
be monitoring a location that experiences temperature
changes that occur much more rapidly than in the other
channels. If faster temperature changes must be moni-
tored in one of the temperature channels, the MAX6602
allows channel 1 to be monitored at a faster rate than
the other channels. In this mode (set by writing a 1 to
bit 4 of the configuration 1 register), measurements of
channel 1 alternate with measurements of the other
channels. The sequence becomes channel 1, channel
2, channel 1, channel 3, channel 1, etc. Note that the
time required to measure all five channels is consider-
ably greater in this mode than in the default mode.
Low-Power Standby Mode
Enter software standby mode by setting the STOP bit to
1 in the configuration 1 register. Enter hardware stand-
by by pulling STBY low. Software standby mode dis-
ables the ADC and reduces the supply current to
approximately 30礎. Hardware standby mode halts the
ADC clock, but the supply current is approximately
350礎. During either software or hardware standby,
data is retained in memory. During hardware standby,
the SMBus interface is inactive. During software stand-
by, the SMBus interface is active and listening for
SMBus commands. The timeout is enabled if a start
condition is recognized on SMBus. Activity on the
SMBus causes the supply current to increase. If a
standby command is received while a conversion is in
progress, the conversion cycle is interrupted, and the
temperature registers are not updated. The previous
data is not changed and remains available.

NAME
FUNCTION
7
DXP4
Combined Current Source and A/D Positive Input for Channel 4 Remote Diode. Connect to the anode
of a remote-diode-connected temperature-sensing transistor. Leave floating or connect to V
CC
if no
remote diode is used. Place a 2200pF capacitor between DXP4 and DXN4 for noise filtering.
8
DXN4
Cathode Input for Channel 4 Remote Diode. Connect the cathode of the channel 4 remote-diode-
connected transistor to DXN4.
9
STBY
Standby Input. Drive STBY logic-low to place the MAX6602 in hardware standby mode, or logic-high
for normal operation. Temperature and threshold data are retained in standby mode.
10
N.C.
No Connection. Must be connected to ground.
11
OVERT
Overtemperature Active-Low, Open-Drain Output. OVERT asserts low when the temperature of
channels 1 and 4 exceed the programmed threshold limit.
12
V
CC
Supply Voltage Input. Bypass to GND with a 0.1礔 capacitor.
13
ALERT
SMBus Alert (Interrupt), Active-Low, Open-Drain Output. ALERT asserts low when the temperature of
any channel exceeds the programmed ALERT threshold.
14
SMBDATA SMBus Serial-Data Input/Output. Connect to a pullup resistor.
15
SMBCLK
SMBus Serial-Clock Input. Connect to a pullup resistor.
