POWER-DOWN/POWER-UP CONDITION

DS1259

NOTES:

1. All voltages are referenced to ground.

2. Load capacity is 50 pF.

3. Measured with Pins 11, 12, 13, and 3 open.

4. VTP is the point that PF is driven low.

5. ICCO2 may be limited by the capability of the battery.

6. Trip point voltage for power-fail detect:

VTP = 1.26 x VBAT ± 250 mV

For 5% operation: VBAT = 3.7V max.

For 10% operation: VBAT = 3.5V max.

7. VBATF is the point that BF is driven low. These limits are for 0°C to 70°C operation.

8. Battery leakage is the internal energy consumed by the DS1259.

9. VCC = +5 volts, tA = 25°C.
