5 / 22 page Analog Integrated Circuit Device Data Freescale Semiconductor 5 34673 ELECTRICAL CHARACTERISTICS STATIC ELECTRICAL CHARACTERISTICS STATIC ELECTRICAL CHARACTERISTICS Table 3. Static Electrical Characteristics Characteristics noted under conditions VIN = 5.0V, -40°C ≤ TA ≤ 85°C, CIN =1µF, COUT = 2.2µF (see Figure 1), unless otherwise noted. Typical values noted reflect the approximate parameter means at VIN = 5.0V and TA = 25°C under nominal conditions, unless otherwise noted. Characteristic Symbol Min Typ Max Unit POWER INPUT Input Voltage Range(5) VIN 2.6 - 6.6 V VIN Pin Supply Current Charger enabled(6) Charger disabled IIN - - 1400 - - 350 µA Regulated Output Voltage VIN = 5.0V; IBAT = 10mA; TA = 25°C VIN = 5.0V; IBAT = 10mA; TA = -20 to 70°C VIN = 5.0V; IBAT = 10mA; TA = -40 to 85°C VBAT 4.185 4.170 4.158 4.20 4.20 4.20 4.215 4.230 4.230 V Power MOSFET On Resistance VBAT = 4.0V; IBAT = 500mA; ICHG = 600mA RDS(ON) - 330 475 m Ω BAT Pin Standby Current VIN not powered or charger disabled ISTDBY - - 1.0 µA Power On Reset Rising VIN threshold Falling VIN threshold VPOR 3.0 - - 2.4 3.9 2.6 V VIN-BAT Offset Voltage Rising threshold Falling threshold VOS - 1.0 - - 60 22 mV Over-voltage Protection Rising Threshold VOVP 6.6 6.8 7.0 V Over-voltage Protection-Threshold Hysteresis VOVPHYS - 400 - mV CHARGE CURRENT Constant-current Mode Charge Current Range(7) ICHG 0.05 - 1.2 A ICHG Accuracy For ICHG between 300mA to 1200mA (Tested at 450mA) For ICHG between 50mA to 300mA(7) ICHG 94 90 100 100 106 110 % Trickle-Mode Charge Current ITRKL 16 20 24 % ICHG End-of-Charge (EOC) Threshold When ICHG is set to 450mA IEOC 35 45 55 mA ISET Pin Voltage for ICHG Reference(7) VISET - 1.0 - V Notes 5. Refer to the Power-on-Reset parameter for VIN turn on and turn off values. 6. Supply current does not include the current delivered to the battery through the BAT pin. 7. Not tested. Guaranteed by design. |
