Note 1. Absolute maximum ratings indicate limits which, when exceeded, may result in damage to the component. Electrical specifi-

cations do not apply when operating the device outside its rated operating conditions.

Note 2. Specified min/max limits are production tested or guaranteed through correlation based on statistical control methods.

Measurements are taken at constant junction temperature as close to ambient as possible using low duty pulse testing.

Note 4. Guaranteed by design.

Note 5. In order to get a valid low-battery-output (LBO) signal, the input voltage must be lower than the low-battery-input (LBI) thresh-

the battery terminal.
