8.3 Power Supply Recommendations

The device is qualified for both automotive and industrial applications. The normal power supply connection is a 12V automotive system. The supply voltage should be within the range specified in the Recommended Operating Conditions.

Table 8-6 Voltage Operating Ranges
VBB VOLTAGE RANGE NOTE
3V to 6V

Extended lower 12V automotive battery operation such as cold crank and start-stop. Device is fully functional and protected but some parametrics such as RON, current limit accuracy and timing parameters can deviate from specifications. Check the individual specifications in Electrical Characteristics to confirm the voltage range it is applicable for.
6V to 18V

Nominal 12V automotive battery voltage range. All parametric specifications apply and the device is fully functional and protected.
18V to 24V

Extended upper 12V automotive battery operation such as double battery. Device is fully functional and protected but some parametrics such as RON, current limit accuracy, and timing parameters can deviate from specifications. Check the individual specifications in Electrical Characteristics to confirm the voltage range it is applicable for.
35V

Load dump voltage. Device is operational and lets the pulse pass through without being damaged but does not protect against short circuits.
