NAME
FUNCTION
1
1
V
CC
Supply Voltage Input, +3V to +5.5V. Bypass to GND with a 0.1礔 capacitor. A 200&
series resistor is recommended but not required for additional noise filtering. See
Typical Operating Circuit.
2
3
DXP
Combined Remote-Diode Current Source and A/D Positive Input for Remote-Diode
Channel. DO NOT LEAVE DXP UNCONNECTED; connect DXP to DXN if no remote
diode is used. Place a 2200pF capacitor between DXP and DXN for noise filtering.
3
4
DXN
Combined Remote-Diode Current Sink and A/D Negative Input. DXN is internally
biased to one diode drop above ground.
4
6
OVERT1
Overtemperature Active-Low Output, Open-Drain. Output is logic low only when
temperature is above the software programmed threshold.
5
7, 8
GND
Ground
6
9
ALERT
SMBus Alert (Interrupt) Active-Low Output, Open-Drain. Asserts when temperature
exceeds user-set limits (high or low temperature). Stays asserted until acknowledged
by either reading the Status register or by successfully responding to an Alert
Response address. See ALERT Interrupts.
7
12
SMBDATA
SMBus Serial-Data Input/Output, Open-Drain
8
14
SMBCLK
SMBus Serial-Clock Input
5
ADD
SMBus Address-Select Pin. The MAX6659 is set to one of three available addresses
(connect to V
CC
, GND, or leave open). See Slave Addresses section.
10
OVERT2
Overtemperature Active-Low Output, Open-Drain. Output is logic low only when
temperature is above the software programmed threshold.
15
STBY
Hardware Standby Input. Temperature and comparison threshold data are retained in
standby mode. If STBY is low, the IC is put into standby mode.
2, 11, 13, 16
N.C.
Not internally connected. Do not make connections to these pins.
