The LT3796I and LT3796I-1 may cause permanent damage to the device. Exposure to any Absolute are guaranteed to meet performance specifications over the –40°C to Maximum Rating condition for extended periods may affect device 125°C operating temperature range. The LT3796H and LT3796H-1 are reliability and lifetime. guaranteed over the full –40°C to 150° C operating junction temperature Note 2: Do not apply a positive or negative voltage source to TG and GATE range. High junction temperatures degrade operating lifetimes. Operating pins, otherwise permanent damage may occur. lifetime is derated at junction temperatures greater than 125°C. Note 3: Operating maximum for INTV Note 5: Measured in servo. See Figure 9 for details. CC is 8V.
