PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Voltage Sense Comparator Section (VSC) Threshold Voltage STAT0 = 0, STAT1 = 0, Function of VREF 0.945 0.95 0.955 V/V STAT0 = 1, STAT1 = 0, Function of VREF 0.895 0.9 0.905 V/V Over Charge Taper Current Comparator Section (OCTIC) Threshold Voltage Function of 2.3V REF, CA- = CAO 0.99 1 1.01 V/V Input Bias Current OVCTAP = 2.3V –0.5 –0.1 µA Logic 5V Reference Section (VLOGIC) VLOGIC VCC = 15V 4.875 5.0 5.125 V Line Regulation 8.8V < VCC < 35V 3 15 mV Load Regulation 0 < IO < 10mA 3 15 mV Reference Comparator Turn-on Threshold 4.3 4.8 V Short Circuit Current VREF = 0V 30 50 80 mA Output Stage Section ISINK Continuous 50 mA IPEAK 100 mA VOL IO=50mA 1 1.3 V Leakage Current VOUT=35V 25 µA STAT0 & STAT1 Open Collector Outputs Section Maximum Sink Current VOUT = 8.8V 6 10 mA Saturation Voltage IOUT = 5mA 0.1 0.45 V Leakage Current VOUT = 35V 25 µA STATLV Open Collector Outputs Section Maximum Sink Current VOUT = 5V 2.5 5 mA Saturation Voltage IOUT = 2mA 0.1 0.45 V Leakage current VOUT = 5V 3 µA UVLO Section Turn-on Threshold 6.8 7.8 8.8 V Hysteresis 100 300 500 mV ICC Section ICC (run) (See Fig. 1) 13 19 mA ICC (off) VCC = 6.5V 2 mA Note 2: VIO is measured prior to packaging with internal probe pad. Note 3: Thermistor initial accuracy is measured and trimmed with respect to VAO; VAO = VA–. CA–: The inverting input to the current error amplifier. CAO: The output of the current error amplifier which is internally clamped to approximately 4V. It is internally connected to the inverting input of the PWM comparator. CS–, CS+: The inverting and non-inverting inputs to the current sense amplifier. This amplifier has a fixed gain of five and a common-mode voltage range of from –250mV to +VCC. CSO: The output of the current sense amplifier which is internally clamped to approximately 5.7V. CHGENB: The input to a comparator that detects when battery voltage is low and places the charger in a trickle charge state. The charge enable comparator makes the output of the voltage error amplifier a high impedance while forcing a fixed 10 µA into CA– to set the trickle charge current. PIN DESCRIPTIONS |
