ALARM COMPARATORS AND INTERRUPT THRESHOLDS

Alarm interrupt threshold values can be programmed by the user in the designated SRAM memory registers in the
formats and locations found in Figure 11. Since these thresholds are located in SRAM memory, they must be
reprogrammed if a loss of power to the DS2756 occurs. The DS2756 generates an alarm interrupt to indicate that
one of the following events has occurred:

§ Accumulated Current ³ Current Accumulator Interrupt High Threshold

§ Accumulated Current £ Current Accumulator Interrupt Low Threshold

§ Temperature ³ Temperature Interrupt High Threshold

§ Temperature £ Temperature Interrupt Low Threshold


The host may then poll the DS2756 to determine which threshold has been met or exceeded.
