3 / 12 page LTC1730-4/LTC1730-4.2 3 sn1730 1730fs Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: The LTC1730-4/LTC1730-4.2 are guaranteed to meet performance specifications from 0 °C to 70°C. Specifications over the –40°C to 85°C SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS ICHRG CHRG Pin Pull-Down Current VCHRG = 1V, C/10 Mode 10 40 70 µA TTIMER TIMER Accuracy CTIMER = 0.1µF10 % VGATE GATE Pin Voltage VBAT = 3V 7.5 V VBAT = 4V 10 V TSHDN Thermal Shutdown Temperature 140 °C ∆TSHDN Thermal Shutdown Hysteresis 5 °C ∆VRECHRG Recharge Battery Voltage Offset from VBAT(Full Charged) – VRECHRG (Note 3) 150 mV Full Charged Battery Voltage VNTC_HOT NTC/SHDN Pin Threshold Voltage (Hot) High to Low; VCC = 4V q 1.95 2 2.05 V Hysteresis 50 mV VNTC_COLD NTC/SHDN Pin Threshold Voltage (Cold) Low to High; VCC = 4V q 3.4 3.5 3.6 V Hysteresis 45 mV VSEL SEL Pin Threshold LTC173ECGN-4 0.7 V VACPR ACPR Pin Output Low Voltage LTC1730EGN-4, IACPR = 5mA 0.6 V VFAULT FAULT Pin Output Low Voltage LTC1730EGN-4, IFAULT = 3mA 1.2 V VCHRG CHRG Pin Output Low Voltage ICHRG = 5mA, Charging Mode 0.9 V The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VCC = 6V unless otherwise noted. DC ELECTRICAL CHARACTERISTICS operating temperature range are assured by design, characterization and correlation with statistical process controls. Note 3: For the LTC1730-4 version, the full charged VBAT value is typically 4.1V. |
