Notes

94.

This parameter is production tested up to TA = 125°C and guaranteed by process monitoring up to TJ = 150°C.

95.

When over-current occurs, the high side stays ON with limited current capability and the HS1CL flag is set in the HSSR

96.

When open-load occurs, the flag (HS1OP) is set in the HSSR

97.

When short circuit occurs and if HVSE flag is enabled, HS1 automatic shutdown.

98.

When over-temperature shutdown occurs, both high sides are turned off. All flags in HSSR are set.

99.

Guaranteed by characterization but, not production tested

100.

Analog multiplexer input disconnected from L1 input pin.

101.

Analog multiplexer input connected to L1 input pin.

Table 33. Static Electrical Characteristics (continued)

Characteristics noted under conditions 5.5 V

≤ VSUP ≤ 18 V, -40°C ≤ TA ≤ 125°C for the 33910 and -40°C ≤ TA ≤ 85°C for the

34910, unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal

conditions, unless otherwise noted.
