NAME
FUNCTION
1
1
PWM_OUT
Digital Output (Open Drain). Pulse-width modulated output to external power transistor.
Requires a pullup resistor (10k& typ).
2
2
TACH/AIN
Digital/Analog Input. Fan tachometer input. May be reprogrammed as an analog input to
measure speed of a 2-wire fan. See Figure 5.
3
CRIT0
Input. Used in conjunction with CRIT1 to set THERM and SHUTDOWN default set points
(see Table 1).
4
CRIT1
Input. Used in conjunction with CRIT0 to set THERM and SHUTDOWN default set points
(see Table 1).
3, 4
N.C.
No Connection. Not internally connected.
5
5
GND
Ground
6
6
V
CC
Power Supply. Bypass with a 0.01礔 capacitor to GND.
7
7
THERM
Digital I/O (Open Drain). An active-low thermal-overload output to indicate that the
overtemperature set point has been exceeded. Also acts as an input to provide external
fan control. When this pin is pulled low by an external signal, a status bit is set and the
fan speed is forced full-on. Requires a pullup resistor (10k& typ).
8
8
FAN_FAULT
Digital Output (Active Low, Open Drain). Signals a fan fault. Requires a pullup resistor
(10k& typ).
9
9
DXN
Combined Current Sink and A/D Negative Input. DXN is internally biased to a diode
voltage above ground.
10
10
DXP
Combined Current Source and A/D Positive Input for the Remote-Diode Channel. Do not
leave DXP floating; connect DXP to DXN if no remote diode is used. Place a 2200pF
capacitor between DXP and DXN for noise filtering.
11
SDL
An Active-Low Open-Drain Output. It indicates that local temperature is above the
shutdown set point. Normally used to directly deactivate the CPU power supply.
12
SDR
An Active-Low Open-Drain Output. It indicates that remote temperature is above the
shutdown set point. Normally used to directly deactivate the CPU power supply.
11, 12
N.C.
Internal Connection. Leave floating or connect to GND.
13
13
ADD
Three-State Logic Input. Sets the 2 lower bits of the device SMBus address (Table 2).
ADD is not an ordinary logic input pin; ADD should be connected to V
CC
, GND, or float.
14
14
INT
Digital Output (Open Drain). Can be programmed as an interrupt output for
temperature/fan speed interrupts. Requires a pullup resistor (10k& typ). For the
MAX6653/MAX6663, it can be used also as an input. If pulled low, fan speed is forced to
maximum unless masked.
15
15
SMBDATA
SMBus Serial-Data Input/Output (Open Drain). Requires a pullup resistor (10k& typ).
16
16
SMBCLK
SMBus Serial-Clock Input. Requires a pullup resistor (10k& typ).
12
N.C.
Internal Connection. Leave floating or connect to GND.
