STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 5.5V ≤ V_SUP ≤ 18V, -40°C ≤ T_A ≤ 125°C for the 33910 and -40°C ≤ T_A ≤ 85°C for the
34910, unless otherwise noted. Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal
conditions, unless otherwise noted.

Notes
27. This parameter is production tested up to T_A = 125°C and guaranteed by process monitoring up to T_J = 150°C.
28. When over-current occurs, the high side stays ON with limited current capability and the HS1CL flag is set in the HSSR.
29. When open-load occurs, the flag (HS1OP) is set in the HSSR.
30. When short circuit occurs and if HVSE flag is enabled, HS1 automatic shutdown.
31. When over-temperature shutdown occurs, both High Sides are turned off. All flags in HSSR are set.
32. Guaranteed by characterization but, not production tested
33. Analog multiplexer input disconnected from L1 input pin.
34. Analog multiplexer input connected to L1 input pin.
