DS1259 Datasheet, PDF (5/5 Pages) Dallas Semiconductor – Battery Manager Chip

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. V_TP is the point that PF is driven low.
5. I_CCO2 may be limited by the capability of the battery.
6. Trip point voltage for power-fail detect:
V_TP = 1.26 x V_BAT ± 250 mV
For 5% operation: V_BAT = 3.7V max.
For 10% operation: V_BAT = 3.5V max.
7. V_BATF 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. V_CC = +5 volts, t_A = 25°C.
