8.3 Power Supply Recommendations

The device is qualified for both automotive and industrial applications. The normal power supply connection is a 24V/48V automotive system. The supply voltage must be within the range specified in the Recommended Operating Conditions.

Table 8-3 Voltage Operating Ranges
VBB VOLTAGE RANGENOTE
6V to 58V

Nominal 24V/48V automotive battery voltage range. All parametric specifications apply and the device is fully functional and protected.

58V to 70V for unidirectional clamp version

Extended upper 48V automotive battery operation. 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 Section 6.5 to confirm the voltage range it is applicable for.

58V to 65V for bidirectional clamp version

Extended upper 48V automotive battery operation. 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 Section 6.5 to confirm the voltage range it is applicable for.

65V to 80V for bidirectional clamp version

Max of 100μs duration is allowed in this voltage range. . Device is operational and lets the pulse pass through without being damaged but does not protect against short circuits.
