Electrical Characteristics IN_SET pin and Load Diagnosis (cont’d)
Unless otherwise specified: V_S = 5.5 V to 40 V, T_j = -40 °C to +150 °C, R_SET = 12 kΩ, all voltages with respect to
ground, positive current flowing into pin for input pins (I), positive currents flowing out of the I/O and output pins
(O) (unless otherwise specified)
