Electrical Characteristics (continued)
Unless otherwise stated in a specific test condition the following conditions apply: –40°C ≤ T_J ≤ 125°C; 3 ≤ VDD ≤ 5.5 V, 4.65
V ≤ VPWR ≤ 25 V; HIPWR = GND, PSEL = GND, GD = VAUX, PCTRL = VAUX, AGND = GND; VAUX, VTX, bypassed with
0.1 µF, DVDD bypassed with 0.22 µF, EN12V = GND and EN9V = GND; all other pins open (unless otherwise noted)

(10) Common mode minimum aligns to VBUS UVLO. VBUS must be above its UVLO for the OCP function to be active.
(11) When T_J1 trips a hard reset is transmitted and discharge is disabled, but the bleed discharge is not disabled.
(12) T_J2 trips only when some external heat source drives the temperature up. When it trips the DVDD, and VAUX power outputs are turned
off.
