UNIT LBI Input Current VLBI = 1.4V 1 50 nA CLSEL Input Current SS6622 , CLSEL = OUT 1.4 3 µA SHDN Input Current V SHDN = 0 or VOUT 0.07 50 nA LBO Low Output Voltage VLBI = 0, ISINK = 1mA 0.2 0.4 µA LBO Off Leakage Current VLBO = 5.5V, VLBI = 5.5V 0.07 1 LBI Hystereisis 50 mV Damping Switch Resistance SS6622, VBATT = 2V 50 100 Ω 0.2VOUT SHDN Input Voltage 0.8VOUT V 0.2VOUT CLSEL Input Voltage 0.8VOUT V Note 1: Start-up voltage operation is guaranteed without the addition of an external Schottky diode between the in- put and output. Note 2: Steady-state output current indicates that the device maintains output voltage regulation under load. Note 3: Device is bootstrapped (power to the IC comes from OUT). This correlates directly with the actual battery supply. n TYPICAL PERFORMANCE CHARACTERISTICS 0.01 0.1 1 10 100 1000 0 10 20 30 40 50 60 70 80 90 100 Fig. 1 V OUT=3.3V CLSEL=OUT (0.8A) VIN=2.4V VIN=1.2V Loading (mA) 0.0 0.5 1.0 1.5 2.0 2.5 3.0 0 20 40 60 80 100 120 140 160 I_limit=0.45A , VOUT=3.3V Input battery voltage (V) Fig. 2 No-Load Battery Current vs. Input Battery Voltage I_limit=0.8A , VOUT=3.3V Rev.2.01 6/06/2003 |
