Set EN = 0 V, load D+ to 45 Ω, VD+ = 3.3 V. Set VPWR = 3.5 V, and step up VPWR until 90% of VD+ appears on D+ 3.7 3.95 4.2 V VUVLO_HYST_V PWR VPWR UVLO hysteresis Use standard mode 0 set up. Set EN = 0 V, load D+ to 45 Ω, VD+ = 3.3 V. Set VPWR = 4.3 V, and step down VPWR until D+ falls to 10% of VD+. This gives VUVLO_FALLING_VPWR. VUVLO_RISING_VPWR – VUVLO_FALLING_VPWR = VUVLO_HYST_VPWR for this unit 250 300 400 mV VUVLO_RISING_ VREF VREF rising UVLO threshold in mode 0 Use standard mode 0 set up. Set EN = 0V, load D+ to 45 Ω, VD+ = 3.3 V. Set VREF = 2.5 V, and step up VREF until 90% of VD+ appears on D+ 2.6 2.7 2.9 V VUVLO_HYST_V REF VREF UVLO hysteresis Use standard mode 0 set up. Set EN = 0 V, load D+ to 45 Ω, VD+ = 3.3 V. Set VREF = 3 V, and step down VREF until D+ falls to 10% of VD+. This gives VUVLO_FALLING_VREF. VUVLO_RISING_VREF –VUVLO_FALLING_VREF = VUVLO_HYST_VREF for this unit 75 125 200 mV IVPWR_DISABLE D_MODE0 VPWR disabled current consumption Use standard mode 0. EN = 5 V . Measure current into VPWR 110 µA IVPWR_DISABLE D_MODE1 VPWR disabled current consumption Use standard mode 1. EN = 5 V. Measure current into VPWR 110 µA IVREF_DISABLE D VREF disabled current consumption mode 0 Use standard mode 0. EN = 5 V. Measure current into VREF 10 µA IVPWR_MODE0 VPWR pperating current consumption Use standard mode 0. EN = 0 V. Measure current into VPWR 250 µA IVPWR_MODE1 VPWR operating current consumption Use standard mode 1. EN = 0 V. Measure current into VPWR 350 µA IVREF VREF operating current consumption mode 0 Use standard mode 0. EN = 0 V. Measure current into VREF 12 20 µA ICHG_VREF VREF fast charge current Standard mode 1. 0.1 µF < CVREF < 3 µF. Set-up for charging to 3.3 V. Use a high voltage capacitor that does not derate capacitance up the 3.3 V. Measure slope to calculate the current when CVREF cap is being charged. Test to check this OPEN LOOP method 22 mA ID_OFF_LEAK_S TB Mode 0. Measured flowing into D+ or D– supply, VPWR = 0 V, VD+ or VD– = 18 V, EN = 0 V, VREF = 0 V, D± = 0 V –1 1 µA ID_ON_LEAK_ST B Mode 0. Measured flowing into D+ or D– supply, VPWR = 5 V, VD+ or VD– = 18 V, EN = 0 V, VREF = 3.3 V, D± = 0 V –1 1 µA IVD_OFF_LEAK_ STB Mode 0. Measured flowing out of VD+ or VD– supply, VPWR = 0 V, VD+ or VD– = 18 V, EN = 0 V, VREF = 0 V, D± = 0 V 120 IVD_ON_LEAK_S TB Mode 0. Measured flowing out of VD+ or VD– supply, VPWR = 5 V, VD+ or VD– = 18 V, EN = 0 V, VREF = 3.3 V, D± = 0 V 120 µA IVPWR_TO_VRE F_LEAK Leakage from VPWR to VREF Use standard mode 0. Set VREF = 0 V. Measured current flowing out of VREF pin 1 µA IVREF_TO_VPW R_LEAK Leakage from VREF to VPWR Use standard mode 0. Set VPWR = 0 V. Measured as current flowing out of VPWR pin 1 µA 6.9 Timing Requirements over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT ENABLE PIN AND VREF FAST CHARGE TVREF_CHG VREF fast charge time Time between when 5 V is applied to VPWR, and VREF reaches VVREF_FAST_CHG.
