SC32300B

Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters

specified in the Electrical Characteristics section is not recommended.

NOTES:

(1) The transient negative voltage specification for the LX pin is -6V for 100ns.

(2) Tested according to JEDEC standard JS-001-2012. BST-VDD passed 1.5kV.

(3) Calculated from package in still air, mounted to 3” x 4.5”, 4 layer FR4 PCB with thermal vias under the exposed pad per JESD51 standards.
