PRODUCTION DATA
The device is designed to operate in a 12V automotive system. The device works with two power supply inputs – a typically 12V battery input and a low voltage supply input (5V or 3.3V) typically generated with a DC-DC converter (recommended to reduce quiescent current draw from the battery) or LDO external to the IC from the battery.
The nominal supply voltage range is 6V to 18V as measured at the VBB pin with respect to the GND pin of the device. In this range the device meets full parametric specifications as listed in the Electrical Characteristics table. The device is also designed to withstand voltage transients beyond this range like load dump. When operating outside of the nominal voltage range but within the operating voltage range, the device will exhibit normal functional behavior.
| 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 sense accuracy, over-current thresholds and timing parameters can deviate from specifications. Check the individual specifications in the Electrical Characteristics to confirm the voltage range it is applicable for. |
| 6V to 18V | Nominal supply voltage, all parametric specifications apply. |
| 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 sense accuracy, over-current thresholds, and timing parameters can deviate from specifications. Check the individual specifications in the Electrical Characteristics to confirm the voltage range it is applicable for. The device is short-circuit protected up to 125°C. |
| 24V to 35V | Load dump voltage. Device is operational and lets the pulse pass through without being damaged but does not protect against short circuits. |
