(1) Tested both under input low condition and high condition.
(2) The pulse 2-A voltage is 54-V maximum from VBB with respect to ground. A voltage suppressing mechanism must be used to pass
Level III. This test was run with an 2-μF capacitor from VBB to ground.
(3) GND pin network is a 1-kΩresistor in parallel with a diode BAS21-7-F.
(4) Status II: The function does not perform as designed during the test, but returns automatically to normal operation after the test.

(1) Tested both under input low condition and high condition (DIAG_EN, EN, and VBB are all classified as inputs).
(2) Considering the worst test condition, the device is tested without any filter capacitors on VBB and VOUT.
(3) The GND pin network is a 1-kΩresistor in parallel with a diode BAS21-7-F.
(4) Status II: The function does not perform as designed during the test, but returns automatically to normal operation after the test.
(5) Select a 36-V external suppressor.
9.3 Power Supply Recommendations
The device is qualified for both automotive and industrial applications. The normal power supply connection is a
12-V automotive system. The supply voltage must be within the range specified in the Recommended Operating
Conditions.
表9-4. Voltage Operating Ranges
VBB Voltage Range
Note
Extended lower 12-V automotive battery operation such as cold crank and start-stop. Device
is fully functional and protected but some parametrics such as RON, current sense accuracy,
current limit accuracy and timing parameters can deviate from specifications. Check the
individual specifications in the Electrical Characteristics to confirm the voltage range it is
applicable for.
3 V to 6 V
Nominal 12-V automotive battery voltage range. All parametric specifications apply and the
device is fully functional and protected.
6 V to 18 V
18 V to 24 V
35 V
Extended upper 12-V automotive battery operation such as double battery. Device is fully
functional and protected but some parametrics such as RON, current sense accuracy, current
limit accuracy, and timing parameters can deviate from specifications. Check the individual
specifications in the Electrical Characteristics to confirm the voltage range it is applicable for.
Load dump voltage. Device is operational and lets the pulse pass through without being
damaged but does not protect against short circuits.
