Protection and Diagnostic Functions
9.2
Electrical Characteristics
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
V
IN = 6V to 40V; 4.5V ≤ VFBH ≤ 40V, 4.5V ≤ VFBL ≤ 40V, Tj = -40 °C to +150 °C, all voltages with respect to ground,
positive current flowing into pin; (unless otherwise specified)
