DS1682

4 of 13

ALARM# (Alarm Output) - When there is a non-zero number programmed into the Alarm Trip Point

register and a zero in the AoR bit of the Configuration register, the Alarm# output will be enabled and the

DS1682 will begin to monitor the values in the ETC for the programmed value in the Alarm Trip Point

register. When the Polarity bit in the Configuration register is set to a zero the Alarm# output will

become active when the Alarm Trip Point is exceeded. When the Polarity bit is set to a one, the Alarm#

output will be inactive until the Alarm Trip Point is exceeded. With the AoR bit in the Configuration

register set to a one, the Reset Enable input will be mapped to the Alarm# pin.

N/C (No Connect) – This pin is not connected internally.
