Figure 17. Power Down/Up Mode AC Waveforms
Table 9. Power Down/Up AC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 2.0 to 5.5V (except where noted).
2. VCC fall time should not exceed 5mV/s.
Table 10. Power Down/Up Trip Points DC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 2.0 to 5.5V (except where noted).
2. All voltages referenced to VSS.
3. In 3.3V application, if initial battery voltage is
≥ 3.4V, it may be necessary to reduce battery voltage (i.e., through wave soldering
the battery) in order to avoid inadvertent switchover/deselection for VCC – 10% operation.
4. Switch-over and deselect point.
