Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2: The BL9110 is guaranteed to meet performance specifications from 0°C to 70°C. Specifications over the –40°C to
85°C operating temperature range are assured by design, characterization and correlation with statistical
process controls.
Note 3: Y: Year of assembly manufacturing
W: Week of assembly manufacturing
SS: Lot ID (the 7th and 8th number of Lot numbers)
VVV: Voltage code (for example 100 stands for 1.0V)
Note 4: Thermal Resistance is specified with approximately 1 square of 1 oz copper.
