Safety Regulatory Approvals The MAX22700 and the MAX22702 have a maximum UL According to UL1577 R of 1.25 for the low-side driver, and the DSON cUL According to CSA Bulletin 5A MAX22701 has an R of 2.5 for the low-side driver. DSON VDE 0884-11 Basic Insulation (Wide SOIC) (Pending) All devices have a maximum R of 4.5 for the high- DSON side driver.

The MAX22700MAX22702 are available either in an 8-pin wide-body SOIC package with 8mm creepage and clearance, or in a smaller 8-pin narrow-body SOIC pack- age with 4mm of creepage and clearance. The narrow SOIC package material has a minimum comparative track- ing index (CTI) of 600, which gives it a group I rating in creepage tables, while the wide SOIC package material has a minimum CTI of 400, which gives it a group II rating in creepage tables. All devices are rated for operation at ambient temperatures of -40C to +125C.
