ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
Table 35. Static Electrical Characteristics (continued)
Characteristics noted under conditions 5.5 V ≤ V_SUP ≤ 18 V, -40°C ≤ T_A ≤ 125°C for the 33912 and -40°C ≤ T_A ≤ 85°C for the
34912, unless otherwise noted. Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal
conditions, unless otherwise noted.

Notes
98. This parameter is production tested up to T_A = 125°C and guaranteed by process monitoring up to T_J = 150°C.
99. When over-current occurs, the corresponding high side stays ON with limited current capability and the HSxCL flag is set in the HSSR.
100. When open load occurs, the flag (HSxOP) is set in the HSSR.
101. When short-circuit occurs and if HVSE flag is enabled, both HS automatic shutdown.
102. When over-temperature shutdown occurs, both high sides are turned off. All flags in HSSR are set.
103. When over-current occurs, the corresponding low side stays ON with limited current capability and the LSxCL flag is set in the LSSR.
104. When open load occurs, the flag (LSxOP) is set in the LSSR.
105. When short-circuit occurs and if HVSE Flag is enabled, both LS automatic shutdown
106. When over-temperature shutdown occurs, both low sides are turned off. All flags in LSSR are set.
107. Guaranteed by characterization but not production tested
