MAX6683
The MAX6683 system supervisor monitors multiple
power-supply voltages, including its own, and also fea-
tures an on-board temperature sensor. The MAX6683
converts voltages to an 8-bit code and temperatures to
an 11-bit (10-bit-plus-sign) code using an analog-to-
digital converter (ADC). A multiplexer automatically
sequences through the voltage and temperature mea-
surements. The digitized signals are then stored in reg-
isters and compared to the over/underthreshold limits
programmed over the SMBus™/I
2
C™-compatible 2-
wire serial interface.
When a temperature measurement exceeds the pro-
grammed threshold, or when an input voltage falls out-
side the programmed voltage limits, the MAX6683
generates a latched interrupt output
ALERT.
Three
interrupt modes are available for temperature excur-
sions. These are default mode, one-time interrupt
mode, and comparator mode. The
ALERT
output is
cleared, except for temperature interrupts generated in
comparator mode, by reading the Interrupt Status reg-
ister (Table 5). The
ALERT
output can also be masked
by writing to the appropriate bits in the Interrupt Mask
register (Table 6) or by setting bit 1 of the Configuration
register (Table 4) to zero. The MAX6683 SMBus/I
2
C-
compatible interface also responds to the SMB alert
response address.
