Notes:

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

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

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 temperature as possible using low duty cycle

pulse testing.

3. Guaranteed by design.

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

threshold for a duration greater than the low battery hold time (tHOLD(LBI)). This feature eliminates false triggering due to

voltage transients at the battery terminal.
