ELECTRICAL CHARACTERISTICS (1) Common conditions (unless otherwise noted) are: [3 V ≤ ( V(A), V(C) ) ≤ 18 V ] , C(BYP) = 2200 pF, R(RSET) = open, EN = 2 V, GATE = open, –40°C ≤ TJ ≤ 125°C, positive currents into pins, typical values are at 25°C, all voltages with respect to GND. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT A, C V(C) rising 2.25 2.5 Supply UVLO V Hysteresis 0.25 | I(A) |, Gate in active region 0.66 1 A current mA | I(A) |, Gate saturated high 0.1 Worst case, gate in active region, V(AC) ≤ 0.1 V 4.25 6 C current mA Gate saturated high, V(AC) ≤ 0.1 V 1.2 EN Threshold voltage V(EN) rising 1.25 1.3 1.35 V Hysteresis 29 mV V(AC) = 0.1 V, V(EN)↑ : 1.1 V → 1.4 V, measure 0.65 1 period to V(GATE) = 0.25 V Response time ms V(AC) = 0.1 V, V(EN)↓: 1.4 V → 1.1 V, measure 0.3 0.6 period to V(GATE) = V(ON) - 0.25 V Leakage current (source or sink) V(EN) = 0.5 V 1 mA TURN ON Forward turn-on voltage - VON V(A-C) 58 65 71 mV TURN OFF Gate sinks > 10 mA at V(GATE-A) = 2 V V(A-C) falling, R(RSET) = open 1 3 5 Turn-off threshold voltage mV V(A-C) falling, R(RSET) = 28.7 kΩ -17 -13.25 -10 V(A-C) falling, R(RSET) = 3.24 kΩ -170 -142 -114 V(A) = 12 V, V(A-C): 20 mV → –20 mV, Turn-off delay 70 ns V(GATE-A) begins to decrease V(A) = 12 V, C(GATE-GND) = 0.01 mF, V(A-C): Turn-off time 20 mV → –20 mV, measure the period to 130 ns V(GATE) = V(A) (1) Parameters with only typical values are provided for reference only, and do not constitute part of TI's published device specifications for purposes of TI's product warranty.
