Forward Battery SLIC and Ringing Relay for TR-57 Applications
State Definitions
Special States
Battery Out of Range
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Note: The IC can be damaged unless all ground connections are applied before, and removed after, all other connections. Furthermore, when

This mode is caused by a battery out of range; that is, the battery voltage rising above or below a specified
threshold.
Upon reaching the specified high or low battery voltage, the device will enter an all-off mode.
Upon the battery returning to the specified normal operating range, the device will re-enter the state it was in
prior to the low battery shutdown.
Hysteresis is built in to prevent oscillation. In this mode, supervision output NSTAT is forced low (off-hook)
regardless of loop status or if the disconnect logic state is selected.
powering the device, the user must guarantee that no external potential creates a voltage on any pin of the device that exceeds the
device ratings. For example, inductance in a supply lead could resonate with the supply filter capacitor to cause a destructive overvoltage.
