5 / 56 page  TPS2482 TPS2483 www.ti.com SLUSAW1 A – DECEMBER 2012 – REVISED MARCH 2013 ELECTRICAL CHARACTERISTICS (Hotswap Section) (continued) Unless otherwise noted, minimum and maximum limits apply across the recommended operating junction temperature and voltage ranges, typical specifications are at TJ = 25°C, VVCC = 48 V, VPROG = 2 V, VTIMER = 0 V, all outputs unloaded. Voltages are with respect to GND and positive currents are into pins. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Power-Good Output (PG) VOUT = 0 V, IPG = 2 mA 0.1 0.25 Output voltage (sinking), PG VPG_OL = false VOUT = 0 V, IPG = 4 mA 0.25 0.5 VSENSE = VVCC, VOUT rising, V(SENSE-OUT) VPGTL PG = true threshold voltage 0.8 1.25 1.7 decreasing V VSENSE = VVCC, VOUT falling, V(SENSE-OUT) VPGTH PG = false threshold voltage 2.2 2.7 3.2 increasing VHYST_PG PG threshold hysteresis VSENSE = VVCC 1.4 PG deglitch delay, detection tDPG to output, rising and falling VSENSE = VVCC 5 9 15 ms edges Output leakage current, PG = VPG = VVCC 10 μA true Output Voltage Feedback Input (OUT) VOUT = VVCC, VEN = Hi; (sinking) 8 20 IOUT Input bias current μA VOUT = 0 V, VEN = Lo; (sourcing) 18 40 Enable Input (EN) VEN_H Threshold VEN rising 1.32 1.35 1.38 V VEN_L Threshold VEN falling 1.20 1.25 1.30 EN threshold hysteresis 100 mV IEN Input bias current VEN = 30 V 1 μA ELECTRICAL CHARACTERISTICS (Monitor Section) Boldface limits apply over the recommended junction temperature range, otherwise limits apply at TA = 25°C. Unless otherwise noted, VS = 3.3 V, VINP = 12 V, VSHUNT = (VINP – VINM) = 0 mV, default power-on mode. Voltages are with respect to GND and positive currents are into pins. PARAMETER CONDITIONS MIN TYP MAX UNIT Monitor Supply (VS) Operating supply range 2.7 5.5 V Quiescent current, default operating mode No SCL clock 330 420 μA Quiescent current, power-down mode No SCL clock 0.5 2 μA Monitor Sense Inputs (VINP, VINM) Shunt voltage input range -81.9175 81.9175 mV Bus voltage input range(1) 0 36 V Common-mode rejection CMRR VVINP = 0 V to 36 V 126 140 dB Shunt offset voltage, RTI(2) VOS ±2.5 ±10 μV vs Temperature 0.1 0.4 μV/°C vs Power supply PSRR VS = 2.7 V to 5.5 V 2.5 μV/V Bus offset voltage, RTI(2) VOS ±1.25 ±7.5 mV vs Temperature 10 40 μV/°C vs Power supply PSRR VS = 2.7 V to 5.5 V 0.5 mV/V Input bias current IVINP 10 μA Input bias current, plus parallel IVINM + 10 μA || resistance RVINM 830k Ω (1) While the input range is limited to 36 V, the full-scale range of the ADC scaling is 40.96 V. See the Basic ADC Functions section. Do not apply more than 36 V. (2) RTI = Referred-to-input.
