ten to the Serial Address Register. This code overwrites
the code set by connection of the ADD pin, until the
MAX6683 is taken through a POR cycle.
ADC and Multiplexer
The ADC integrates over a 66ms period, an integral
multiple of the line period with excellent noise rejection.
The internal oscillator is trimmed to produce a 66ms
conversion time for temperature and 33ms for each
voltage. This is equivalent to 4 and 2 cycles of 60Hz,
respectively, and provides protection against noise
pickup from the main supply. The internal oscillator fre-
quency can be changed to provide the same protection
against 50Hz by setting bit 7 in the Configuration
Register to 1 (Table 4). The multiplexer automatically
sequences through the inputs, measuring voltages and
temperature.
Low-Power Shutdown Mode
Setting bit 0 in the Configuration Register to zero stops
the monitoring loop and puts the MAX6683 into low-
power shutdown mode. In this mode, the SMBus/I
2C
interface remains active, and the supply current drops
to 10A or less.
Power-On Reset
The MAX6683 POR supply voltage is typically 2V.
Below this supply voltage, all registers are reset, the
device is put into shutdown mode, and the SMBus/I
2C
interface is inactive.
Alarm Threshold Registers
Two registers, a hot temperature limit (THOT) at 39h and
a hot temperature hysteresis (THYST) at 3Ah, store
alarm threshold data (Table 1). If a measured tempera-
ture exceeds the value of THOT, an ALERT is asserted.
Alerts are cleared and reasserted depending on
the interrupt mode selected in the Temperature
Configuration Register (see ALERT Interrupts).
